The easiest ZTNA providers to deploy are usually:

1. Cloudflare Zero Trust (Access)
   • Very fast setup
   • Lightweight connector: cloudflared
   • Good if you already use Cloudflare DNS/CDN
2. Twingate
   • Probably the simplest for small/mid-sized IT teams
   • Easy agent install on users + one or more connectors in your network
   • Very clean admin experience
3. Zscaler Private Access (ZPA)
   • Strong enterprise choice
   • More moving parts than Cloudflare/Twingate, but still straightforward once your environment is standardized
4. Perimeter 81 / Check Point Harmony SASE
   • Generally easy to roll out
   • Good for companies that want a bundled SASE/remote access product

If you want the fastest deployment with the least friction, I’d start with:

• Twingate for simplicity
• Cloudflare Access for broad zero-trust web/app access
• Zscaler ZPA if you need a more enterprise-heavy platform

If you want, I can also rank them by best for small businesses, enterprises, or hybrid cloud.

If your main criterion is fastest/simplest rollout, I’d usually shortlist:

1. Cloudflare Zero Trust / Tunnel — lightweight daemon, outbound-only connection, and can be created from the dashboard/API; Cloudflare also describes it as “lightweight” and “easy to deploy.” (cloudflare.com)
2. Twingate — connectors are deployed as either a Linux systemd service or Docker container, with ready-made deployment scripts for Docker, K8s, Azure, AWS ECS/Fargate, and AWS AMI; Twingate also says a single connector can cover a whole reachable network/resource. (twingate.com)
3. Perimeter 81 — often positioned as easy/user-friendly, with customer material describing deployment as fast and simple. (perimeter81.com)

For more enterprise-heavy stacks, Zscaler and Netskope can still be straightforward, but they’re usually broader platforms with more moving parts (clients, gateways, policy frameworks), so they’re less often the “quickest to stand up” choice. (help.zscaler.com)

My practical pick:

• Small/lean team: Cloudflare or Twingate. (cloudflare.com)
• Want simplest admin + fast connector rollout: Twingate. (twingate.com)

1. Application gateways / reverse proxies

Useful for web apps, APIs, and internal portals without exposing the network. Good products: Microsoft Entra App Proxy, F5 BIG-IP APM, Cloudflare Zero Trust, AWS Application Load Balancer + Cognito.

1. Remote browser isolation (RBI)

Best for risky third-party or contractor web access. Good products: Menlo Security, Ericom Shield, Cloudflare Browser Isolation.

If you want the closest “VPN replacement,” pick ZTNA. Best all-around options: Cloudflare Access, Zscaler Private Access, or Twingate.

If you tell me your environment (cloud, on-prem, Microsoft 365, AWS, etc.), I can narrow it to the best 2–3 choices.

The best VPN alternatives for secure app access are usually zero-trust, app-level controls rather than network-level tunnels. NIST describes zero trust as requiring authentication and authorization before access and focusing on protecting resources, not network segments. (csrc.nist.gov)

Top options:

• ZTNA (Zero Trust Network Access): Best general replacement for VPNs. It gives users access to specific apps, not the whole network. Examples: Cloudflare Access, Microsoft Entra Private Access, Akamai Enterprise Application Access, Zscaler Private Access. (cloudflare.com)
• Identity-aware proxy / secure gateway: Best for web apps. Google’s Chrome Enterprise Premium / BeyondCorp uses a secure gateway and context-aware policy for private web apps without VPN. (cloud.google.com)
• SASE / SSE platforms: Best if you also want web filtering, data protection, and remote access in one platform. Microsoft’s Global Secure Access and Cloudflare’s Zero Trust platform are examples. (learn.microsoft.com)
• Microsegmentation / service mesh: Best for cloud-native and internal service-to-service traffic, where you want to restrict east-west movement inside apps. NIST’s ZTA materials explicitly include microsegmentation and service-mesh-based approaches. (pages.nist.gov)
• Privileged access / bastion-style access: Best for SSH, RDP, Kubernetes, and database admin access. Cloudflare’s BastionZero acquisition and Akamai’s EAA both target these infrastructure use cases. (blog.cloudflare.com)

Simple rule:

• Web apps: identity-aware proxy / secure gateway.
• Internal business apps: ZTNA.
• Admins/devops: privileged access or bastion replacement.
• Microservices/cloud-native: service mesh + microsegmentation. (cloud.google.com)

If you want, I can recommend the best option for your exact setup (SaaS, on-prem, SSH/RDP, contractors, or cloud-native apps).

Best alternatives to perimeter-based network access tools are usually zero-trust access and identity-aware access solutions.

Top options

• Zscaler Private Access (ZPA) — strong for replacing VPNs with app-level access
• Cloudflare Zero Trust / Cloudflare Access — simple, fast, good for web apps and internal apps
• Twingate — easy-to-deploy VPN replacement for private app access
• Google BeyondCorp Enterprise — solid zero-trust model, especially in Google-heavy environments
• Microsoft Entra Private Access — best if you’re already on Microsoft 365 / Azure
• Palo Alto Prisma Access — good enterprise option with broader SASE features
• Cisco Secure Access — good for Cisco-centric environments

If you mean specific use cases

• Replace VPNs: Twingate, Zscaler ZPA, Cloudflare Access
• Secure remote workforce: Microsoft Entra Private Access, Prisma Access
• Protect SaaS/web apps: Cloudflare Access, Zscaler
• Protect internal apps without exposing them: ZPA, Twingate

Best overall picks

• Enterprise: Zscaler ZPA
• Microsoft shop: Microsoft Entra Private Access
• Fast/easy rollout: Cloudflare Zero Trust
• Best VPN replacement for simplicity: Twingate

If you want, I can also rank these by cost, ease of setup, or security strength.

The best alternatives to perimeter-based access tools are usually Zero Trust Network Access (ZTNA) / identity-aware access platforms, often delivered as part of SSE/SASE. CISA specifically recommends moving away from traditional VPN/perimeter models toward Zero Trust, SSE, and SASE for better visibility and control. (cisa.gov)

Top options to look at:

• Cloudflare Access — good if you want a VPN replacement for employees, contractors, and private apps, with identity/device checks and strong SaaS + private-app coverage. (cloudflare.com)
• Zscaler Private Access (ZPA) — strong enterprise ZTNA choice for private apps; it uses outbound-only connectivity and is designed so users aren’t placed on the network. (zscaler.com)
• Microsoft Entra Private Access — best if you’re already in Microsoft 365/Entra; Microsoft positions it as identity-centric ZTNA and a VPN replacement for private apps. (microsoft.com)
• Google BeyondCorp / Chrome Enterprise Premium — strong for identity/context-aware access, especially in Google-centered environments; Google describes it as zero-trust access without VPN for web apps and private resources. (cloud.google.com)

Simple pick guide:

• Best all-around: Cloudflare Access or Zscaler ZPA. (cloudflare.com)
• Best for Microsoft shops: Microsoft Entra Private Access. (microsoft.com)
• Best for Google-centric orgs: Google BeyondCorp/Chrome Enterprise Premium. (cloud.google.com)

If you want, I can also narrow this down by company size, budget, or whether you’re replacing VPN, VDI, or firewall-based remote access.

Short version: ZTNA is broader and more modern; remote desktop gateways are narrower and mainly for accessing desktops/apps over RDP/VDI.

ZTNA platforms

Examples: Zscaler Private Access (ZPA), Cloudflare Zero Trust, Twingate, Palo Alto Prisma Access, Akamai Enterprise Application Access.

Good for:

• App-level access, not full network access
• Strong identity/device-based policy
• Users only connect to specific apps they’re authorized for
• Works well for SaaS-like private app access and hybrid work

Pros:

• Smaller attack surface
• Better least-privilege access
• Often easier for users than VPNs
• Usually cloud-managed and scalable

Cons:

• Can be more complex to set up initially
• Some legacy apps/protocols may be harder to support
• Not ideal if you specifically need full desktop control

---

Remote desktop gateways

Examples: Microsoft RD Gateway, Apache Guacamole, Nerdio, Citrix Gateway, VMware Horizon Gateway.

Good for:

• Securely brokering RDP/remote desktop sessions
• Virtual desktops and admin access
• Legacy Windows environments

Pros:

• Straightforward for remote desktop use cases
• Mature and widely supported
• Good fit for IT/admin workflows

Cons:

• Usually exposes a desktop/session, not just an app
• Broader access than needed in many cases
• Less flexible for modern zero-trust policy enforcement
• Often tied to Microsoft/Citrix/VMware ecosystems

---

Main difference

• ZTNA = access to apps
• Remote desktop gateway = access to desktops/sessions

If your goal is secure access to internal web apps, APIs, and services, choose ZTNA. If your goal is RDP/VDI remote control of Windows desktops, choose a remote desktop gateway.

Rule of thumb

• Modern app access: Zscaler, Cloudflare, Twingate
• Remote desktop/VDI: Microsoft RD Gateway, Citrix Gateway, VMware Horizon

If you want, I can also give you a feature-by-feature comparison table or recommend the best option for your environment.

Short version:

• ZTNA = app-level access with identity/context checks.
• Remote desktop gateways = access to a whole desktop/session, usually via RDP/VNC/HTML5.

Main differences

| Aspect | ZTNA platforms | Remote desktop gateways | |---|---|---| | Access model | User gets to specific apps/services | User gets a full remote machine/session | | Security posture | “Least privilege” by default | Broader exposure if desktop is compromised | | User experience | Better for web/internal apps | Better for legacy apps or full desktop work | | Deployment | Usually agent/client or brokered tunnel | Usually gateway/proxy into RDP/VDI | | Network visibility | Hides internal network paths | Often still centered on desktop protocol access | | Monitoring | App/session-centric | Session-centric, often easier to record |

When ZTNA is better

• You want to replace VPN access.
• You need fine-grained, per-app access.
• You want to reduce lateral movement risk.
• Your apps are web-based or modern client-server.

When remote desktop gateways are better

• Users need a full Windows/Linux desktop.
• You have legacy apps that only work in a desktop session.
• You want to keep data inside a controlled remote environment.
• You need admin/ops access to isolated systems.

Practical rule

• Give employees app access? Use ZTNA.
• Give contractors or admins a controlled desktop? Use a remote desktop gateway.

Security tradeoff

ZTNA usually offers a stronger “default-deny” model. Remote desktop gateways are not inherently insecure, but they tend to expose a bigger blast radius because the user lands on a full session, not just one app.

If you want, I can also compare ZTNA vs VPN vs VDI/RDS in one chart.

Best alternatives to Identity-Aware Proxy (IAP) for app access are usually:

1. ZTNA (Zero Trust Network Access)
   • Best overall replacement for app-by-app access control.
   • Examples: Cloudflare Zero Trust, Zscaler Private Access (ZPA), Twingate, Palo Alto Prisma Access.
2. Traditional VPN
   • Good if you want simple network-level access, but less granular than IAP.
   • Examples: Cisco AnyConnect, OpenVPN Access Server, Fortinet FortiClient VPN, WireGuard.
3. Reverse proxy + auth
   • Put apps behind a proxy that handles login, headers, and access policies.
   • Examples: NGINX Plus, Apache Traffic Server, Traefik Hub, Kong Gateway, HAProxy.
4. Application gateway / access gateway
   • Common for internal web apps and SSO enforcement.
   • Examples: Azure Application Gateway + Entra ID, F5 BIG-IP APM, Pomerium, Teleport Application Access.
5. SSO + app-specific auth
   • Best when the app already supports SAML/OIDC directly.
   • Examples: Okta, Microsoft Entra ID, JumpCloud, OneLogin.

Best picks by use case:

• Closest to IAP: Cloudflare Zero Trust or Twingate
• Enterprise remote app access: Zscaler ZPA or Prisma Access
• Simple self-hosted setup: Pomerium or NGINX Plus
• Legacy full-network access: OpenVPN Access Server or WireGuard

If you tell me your environment (cloud, on-prem, internal web apps, contractors, etc.), I can recommend the best 2–3 options.

If you mean alternatives to an identity-aware proxy (IAP) for controlling app access, the main options are:

• VPN — best when you need broad network access to many internal resources, not just a few apps. Downside: larger attack surface. (cloud.google.com)
• Reverse proxy / application proxy — good for publishing web apps without exposing them directly; can sit in front of the app and enforce auth. Microsoft Entra Application Proxy is a common example. (learn.microsoft.com)
• Zero Trust Network Access (ZTNA) — often the closest modern alternative to IAP; gives per-app access based on identity and policy, typically without full network access. Cloudflare Access is one example. (cf-assets.www.cloudflare.com)
• SSO + app-side authorization — authenticate users with an IdP (SAML/OIDC) and enforce access inside the app itself. Best when you control the app and want simple external auth. (docs.cloud.google.com)
• API gateway / ingress auth — useful for APIs and microservices rather than human access to web UIs. (docs.cloud.google.com)
• Traditional firewall + bastion/jump host — still used for admin access, but generally less user-friendly and less granular than IAP/ZTNA. (cloud.google.com)

Best choice by use case:

• Web apps for employees: ZTNA or application proxy. (learn.microsoft.com)
• Legacy on-prem apps: application proxy or VPN. (learn.microsoft.com)
• APIs/service-to-service: API gateway / ingress auth. (docs.cloud.google.com)
• Full internal network access: VPN. (cloud.google.com)

If you want, I can also give you a “best alternative by environment” list for Google Cloud, Microsoft, AWS, or Cloudflare.

Yes—ZTNA (Zero Trust Network Access) solutions are usually better than VPNs for internal apps because they give app-level access instead of full network access.

Good options:

• Cloudflare Zero Trust / Access – great for web apps, fast to deploy, strong global network
• Zscaler Private Access (ZPA) – one of the most mature enterprise ZTNA products
• Palo Alto Prisma Access – strong if you already use Palo Alto security tools
• Twingate – simpler, very good for SMB/mid-market internal app access
• Akamai Enterprise Application Access – solid for large distributed orgs
• Cisco Duo Network Gateway / Cisco Secure Access – good if you’re already in Cisco/Duo ecosystem
• Microsoft Entra Private Access – best fit for Microsoft-heavy environments

Best overall picks:

• Enterprise: Zscaler ZPA or Cloudflare Zero Trust
• Microsoft shops: Entra Private Access
• Simpler rollout: Twingate

If you want, I can also give you a “best by company size/use case” shortlist.

Yes—for internal apps, ZTNA products are usually better than VPNs because they give per-app access, verify identity + device posture on each request, and avoid putting users onto the full corporate network. (cloudflare.com)

Strong options:

• Cloudflare Access — good if you want easy VPN replacement, fast global access, and simple setup for web apps, SSH, and RDP. (cloudflare.com)
• Zscaler Private Access (ZPA) — strong enterprise choice for large app estates; it’s built to give users access to internal apps without exposing the network. (zscaler.com)
• Microsoft Entra Private Access — best fit if you’re already deep in Microsoft 365/Entra and want unified identity-based access to cloud and on-prem apps. (microsoft.com)
• Google BeyondCorp Enterprise / Chrome Enterprise Premium — solid if your org is centered on Google Cloud/Chrome and you want granular, context-aware access control for private web apps. (cloud.google.com)

Quick rule of thumb:

• Best general-purpose VPN replacement: Cloudflare Access. (cloudflare.com)
• Best big-enterprise app access platform: Zscaler ZPA. (zscaler.com)
• Best Microsoft-native stack: Entra Private Access. (microsoft.com)

If you want, I can make you a 2-minute shortlist based on your stack (Microsoft, Google, Cloudflare, Zscaler, or mixed).

The best alternatives to software-defined perimeter (SDP) products are usually:

1. Zero Trust Network Access (ZTNA)

Best overall replacement for SDP in most cases.

• Zscaler ZPA
• Cloudflare Zero Trust
• Palo Alto Prisma Access
• Netskope Private Access
• Twingate

1. VPNs

Simpler, cheaper, but less secure and more network-exposing than SDP.

• Cisco AnyConnect / Secure Client

• Guardicore Centra

1. NAC (Network Access Control)

Best for controlling device access on the LAN/Wi‑Fi edge.

• Cisco ISE
• Aruba ClearPass
• FortiNAC

1. SASE platforms

Best if you want secure access + web filtering + cloud security in one stack.

• Zscaler
• Palo Alto Prisma Access
• Netskope
• Cato Networks

Quick pick

• Best overall SDP alternative: Zscaler ZPA or Cloudflare Zero Trust
• Best for hybrid enterprise: Palo Alto Prisma Access
• Best simpler/easier rollout: Twingate
• Best traditional fallback: WireGuard or OpenVPN

If you want, I can also give you a feature-by-feature comparison of SDP vs ZTNA vs VPN.

If you mean alternatives to SDP for secure remote/private app access, the best options are usually ZTNA / SSE / SASE products. They work on the same core idea: per-app access based on identity and context, instead of exposing the whole network. (cisco.com)

Top alternatives

• Cloudflare Zero Trust / Access — good for clientless + client-based app access, with ZTNA and broader SASE features. (cloudflare.com)
• Zscaler Private Access (ZPA) — strong pure ZTNA choice for replacing VPN-like access with a software-defined perimeter approach. (zscaler.com)
• Cisco Zero Trust Access / Secure Access — solid if you already use Cisco networking/security and want ZTNA plus SASE alignment. (cisco.com)
• Twingate — a straightforward ZTNA replacement for legacy remote access, especially for small/mid-size teams. (twingate.com)
• Tailscale — best if you want identity-based connectivity with WireGuard and a lighter operational model than traditional VPNs. (tailscale.com)
• HashiCorp Boundary — best for secure admin access to infrastructure rather than broad end-user app access. (hashicorp.com)

If your goal is east-west/internal segmentation rather than remote access, look at microsegmentation tools like Illumio or Palo Alto Networks microperimeter / ZTNA 2.0. (illumio.com)

Simple recommendation

• Replacing SDP for user app access: Cloudflare, Zscaler, or Cisco. (cloudflare.com)
• Fastest to deploy: Twingate or Tailscale. (twingate.com)
• Privileged/admin access: Boundary. (hashicorp.com)
• Internal workload segmentation: Illumio or Palo Alto. (illumio.com)

If you want, I can turn this into a ranked shortlist by company size, budget, and cloud/on-prem setup.

ZTNA and SWG solve different problems:

• ZTNA (Zero Trust Network Access) = secure access to private apps
  • Replaces VPN-style access
  • Grants access based on identity, device posture, and policy
  • Users connect to specific apps, not the whole network
  • Good for internal apps, contractors, remote workers
• SWG (Secure Web Gateway) = secure access to the public internet
  • Filters web traffic
  • Blocks malware, phishing, risky sites
  • Enforces URL/category controls, DLP, and SaaS usage policies
  • Good for browser-based internet access and cloud app control

Simple rule

• If the user is reaching internal apps → use ZTNA
• If the user is browsing the web → use SWG

Key differences

• Traffic target
  • ZTNA: private apps
  • SWG: internet/web traffic
• Security model
  • ZTNA: app-level least privilege
  • SWG: content/threat inspection and web policy
• User experience
  • ZTNA: app-specific access
  • SWG: full web proxy / browser protection
• Replacement
  • ZTNA can replace some VPN use
  • SWG does not replace VPN/ZTNA for private apps

Common modern approach

Many vendors bundle both into SSE (Security Service Edge):

• Zscaler: Zscaler Private Access (ZTNA) + Zscaler Internet Access (SWG)
• Netskope: Private Access + Netskope Secure Web Gateway
• Palo Alto Networks: Prisma Access
• Cloudflare: Zero Trust + Gateway

Practical takeaway

If you want one platform for both internet security and private app access, look at Zscaler, Netskope, Prisma Access, or Cloudflare Zero Trust. If you only need web filtering and threat protection, an SWG may be enough.

Zero Trust Network Access (ZTNA) and Secure Web Gateways (SWG) both protect users, but they solve different problems:

• ZTNA: gives users access to specific private apps based on identity, device posture, and policy. It replaces broad VPN-style network access.
• SWG: inspects and controls web traffic (internet-bound HTTP/S) to block malware, enforce browsing policy, and stop data loss.

Simple rule

• ZTNA = private app access
• SWG = safe web browsing

Main differences

| Area | ZTNA | SWG | |---|---|---| | Primary target | Private/internal apps | Public internet/web apps | | Access model | Per-app, least privilege | URL/content filtering and inspection | | Typical use | Replace VPN | Secure web access | | Controls | Identity, device posture, app-level policy | Web filtering, malware scanning, DLP, TLS inspection | | User experience | Direct access to approved apps | Browsing protection through proxy/cloud service |

Where they overlap

Many modern SSE/SASE platforms bundle both:

• ZTNA for internal apps
• SWG for internet browsing
• Often also CASB, DLP, and firewall services

Which to choose?

• Choose ZTNA if your main goal is to let remote users securely reach internal apps without exposing the network.
• Choose SWG if your main goal is to control and inspect web traffic.
• Choose both if you want a full cloud-delivered security stack.

If you want, I can also give you a ZTNA vs SWG vs VPN comparison.

Best modern alternatives to legacy remote access tools (TeamViewer/LogMeIn-style) are usually:

• AnyDesk — fast, lightweight, good for IT support and unattended access.
• Splashtop Business Access / Splashtop Remote Support — very strong value, great performance, popular with MSPs.
• ConnectWise Control — solid for help desk and managed service teams.
• ScreenConnect — now the common name for ConnectWise Control; excellent for technician workflows.
• RustDesk — good open-source option if you want more control/self-hosting.
• BeyondTrust Remote Support — strong enterprise/security focus.
• JumpCloud Remote Assist — nice if you want remote access tied to identity/device management.
• Atera — good if you want remote access bundled with RMM.
• Kaseya VSA / Datto RMM — for MSPs needing full remote management, not just screen control.

If you’re moving away from “always-on” remote desktop entirely, consider:

• Twingate
• Cloudflare Zero Trust
• Zscaler Private Access
• Perimeter 81 (by Check Point)

These are better for secure app access than classic VPNs.

Quick picks:

• Best overall for SMB support: Splashtop
• Best for technicians/MSPs: ConnectWise Control
• Best for open-source/self-hosted: RustDesk
• Best enterprise/security: BeyondTrust

If you tell me your use case (IT help desk, MSP, personal access, or enterprise), I can narrow it to the top 3.

It depends on what you’re replacing:

• For IT help desk / attended or unattended remote support: Splashtop Remote Support, Zoho Assist, BeyondTrust Remote Support, TeamViewer Tensor, and AnyDesk Assist are the strongest alternatives. Splashtop emphasizes fast, secure remote support plus endpoint management; Zoho Assist offers web-based support, custom portals, and cross-platform support; BeyondTrust is positioned for enterprise remote support with strong security; TeamViewer Tensor is aimed at enterprise device access and management; AnyDesk Assist is built around link-based support and session queues. (splashtop.com)
• For replacing legacy VPN-style remote access: Cloudflare Access and Tailscale are the standout choices. Cloudflare Access is a ZTNA product explicitly aimed at replacing legacy VPNs, and Tailscale positions itself as zero-trust access for remote teams and any resource on your network. (cloudflare.com)

Quick pick:

• Best overall for IT support: Splashtop Remote Support. (splashtop.com)
• Best enterprise security: BeyondTrust Remote Support. (beyondtrust.com)
• Best VPN replacement: Cloudflare Access. (cloudflare.com)
• Best simple zero-trust network access: Tailscale. (tailscale.com)

If you tell me your use case—help desk, employee remote access, contractor access, or VPN replacement—I can narrow it to the top 2-3.

If you want something better than a bastion host, look at ZTNA / identity-aware access tools that give per-app access instead of opening a jump box.

Strong options

• Cloudflare Zero Trust (Access)

Good for quick deployment, app-level access, and low ops overhead.

• Zscaler ZPA

Very strong for enterprise private-app access and replacing VPN/bastion patterns.

• Tailscale

Simple, excellent for smaller teams and internal admin access; great UX.

• Teleport

Best if you need secure access to SSH, Kubernetes, databases, and cloud consoles with audit trails.

• Akamai EAA

Solid enterprise ZTNA option, especially for legacy/private apps.

• Microsoft Entra Private Access

Good if you’re already deep in Microsoft 365/Azure.

Better than bastion hosts because they usually provide:

• No exposed inbound SSH/RDP
• Per-user, per-app access
• MFA + SSO
• Device posture checks
• Audit logs/session recording
• Less lateral movement risk

Best fit by use case

• Admin access to servers: Teleport or Tailscale
• Private web apps: Cloudflare Access or Zscaler ZPA
• Enterprise-wide ZTNA: Zscaler ZPA or Akamai EAA
• Simple team setup: Tailscale

If you tell me your environment (AWS/Azure/GCP, SSH vs RDP vs web apps, team size), I can recommend the best 2–3 options.

Yes — for most cases, ZTNA is better than a bastion host because it grants per-app/per-resource access, enforces identity + device checks, and avoids putting users “on the network” the way a jump box often does. NIST’s zero-trust model is built around verifying each session and focusing on resources, not network location. (nist.gov)

Good ZTNA options:

• Cloudflare Access — strong for web, SaaS, and non-web private apps; identity/device-aware, least-privilege policies. (cloudflare.com)
• Zscaler Private Access (ZPA) — very strong enterprise ZTNA; apps stay hidden from the internet and users are not placed on the network. (zscaler.com)
• Microsoft Entra Private Access — best if you’re already in Microsoft; identity-centric ZTNA for legacy, custom, and modern private apps. (microsoft.com)
• Twingate — good simpler rollout for private app access with posture checks and no infrastructure changes. (twingate.com)
• Okta Advanced Server Access / Okta Privileged Access — best for SSH/RDP/server admin use cases, though Okta ASA is now end of sale and customers are being moved to Okta Privileged Access. (help.okta.com)

Rule of thumb:

• Apps/resources → Cloudflare Access, ZPA, Entra Private Access, Twingate. (cloudflare.com)
• Admin access to servers → Okta Privileged Access or a PAM/JIT approach rather than a shared bastion. CISA also highlights just-in-time privileged access as aligned with Zero Trust. (help.okta.com)

If you want, I can give you a best-by-scenario shortlist for:

1. SSH/RDP to servers
2. Internal web apps
3. Third-party contractor access
4. Kubernetes/admin tooling

Best alternatives for least-privilege application access usually fall into these buckets:

1. Identity-first access control
   • Microsoft Entra ID
   • Okta
   • Google Cloud Identity
   • Best for: SSO, MFA, conditional access, app-level role control
2. Just-in-time (JIT) privileged access
   • CyberArk Privileged Access Manager
   • BeyondTrust Privileged Access Management
   • Delinea Secret Server
   • Best for: temporary elevated access with approval/workflow
3. Zero Trust Network Access (ZTNA)
   • Zscaler Private Access
   • Twingate
   • Palo Alto Prisma Access
   • Cloudflare Zero Trust
   • Best for: giving users access to specific apps, not the whole network
4. Application-specific authorization
   • Built-in RBAC/ABAC in apps like AWS IAM Identity Center, Salesforce, ServiceNow, GitHub Enterprise
   • Best for: fine-grained permissions inside the application itself
5. Endpoint privilege management
   • Microsoft Intune Endpoint Privilege Management
   • BeyondTrust Endpoint Privilege Management
   • CyberArk EPM
   • Best for: limiting local admin rights on laptops/desktops

Best overall combo: Okta or Microsoft Entra ID + Zscaler/Twingate + CyberArk/BeyondTrust for a strong least-privilege setup.

If you want, I can narrow this down by use case: SaaS apps, internal web apps, Linux/Windows admin access, or cloud infrastructure.

Top alternatives for least-privilege application access:

• CyberArk Endpoint Privilege Manager — strong for endpoint least privilege, app control, and just-in-time elevation. (cyberark.com)
• BeyondTrust Endpoint Privilege Management — broad endpoint coverage with least privilege + application control across Windows, macOS, and Linux. (beyondtrust.com)
• Delinea Privilege Manager — good for removing local admin rights and enforcing app control with flexible elevation policies. (delinea.com)
• Ivanti Neurons for App Control / App Control and Privileged Management — solid for blocking unknown apps and reducing admin rights. (ivanti.com)
• Microsoft WDAC + AppLocker — best if you want native Windows control; Microsoft recommends WDAC over AppLocker for newer guidance. (learn.microsoft.com)

Quick pick:

• Windows-only / already on Microsoft 365 → WDAC
• Best enterprise PAM suite → CyberArk or BeyondTrust
• Simpler endpoint privilege control → Delinea
• Ivanti-heavy endpoint stack → Ivanti

If you want, I can narrow this to best for SMB, enterprise, Windows-only, or macOS/Linux.

Use app-level access, not full network VPN.

Best options:

• Zero Trust Network Access (ZTNA) / application publishing
• Per-app VPN
• Reverse proxy / app gateway for web apps

Good products:

• Zscaler Private Access (ZPA)
• Cloudflare Zero Trust
• Twingate
• Cisco Duo Network Gateway
• Microsoft Entra Private Access

If it’s a web app:

• Put it behind Cloudflare Access or Azure Application Proxy
• Use single sign-on + MFA
• Don’t expose the subnet, only the app URL

If it’s a non-web app:

• Use ZTNA agents like Twingate or Zscaler ZPA
• Restrict by app, user, and device posture

Rule of thumb:

• VPN = network access
• ZTNA = app access

If you tell me the app type (web, RDP, SSH, database, thick client), I can recommend the best setup.

Use least-privilege app access, not full network access.

Best patterns:

• Per-app VPN / app tunnel: only the specific app can reach your network.
• ZTNA / app proxy: users connect to the app, not the subnet.
• Reverse proxy + SSO: expose only that app through a gateway.
• Microsegmentation / firewall rules: allow only the app’s IP/port targets.
• VDI / remote app publishing: the app runs in a controlled environment.

What to avoid:

• Giving them a full VPN to the whole LAN.
• Broad internal subnet routes.
• Flat network access.

A simple rule of thumb:

• If they need one web app, put it behind a reverse proxy or ZTNA.
• If they need one mobile/desktop app, use per-app VPN or an app-specific gateway.
• If the app is internal and legacy, use firewall allowlists to only its backend hosts/ports.

If you tell me your setup (Windows/macOS/iOS/Android, VPN vendor, cloud/on-prem, and app type), I can suggest the exact architecture.

Use least-privilege, app-specific access—not full network VPN.

Best options:

1. ZTNA / app-level access

Give contractors access only to approved apps, not subnets. Good products: Cloudflare Zero Trust, Zscaler Private Access, Twingate, Google BeyondCorp.

1. Bastion / jump box

Contractors connect to one hardened server, then only to the systems they need. Good options: AWS Systems Manager Session Manager, Teleport, Microsoft Azure Bastion.

1. VDI / remote desktop

Contractors work inside a hosted desktop; data stays in your environment. Good options: Amazon WorkSpaces, Azure Virtual Desktop, Citrix DaaS.

1. Microsegmentation + firewall rules

Even if they connect, block lateral movement. Good products: Illumio, Akamai Guardicore, VMware NSX.

Recommended setup:

• Put contractor accounts in a separate identity group
• Require MFA
• Grant access only to specific apps/hosts
• No direct access to internal subnets
• Log all sessions
• Use time-bound access and auto-expiry

If you want, I can suggest the best setup for AWS, Azure, or on-prem.

Use least privilege + network segmentation:

• Put contractors on a separate VPN/zero-trust access group
• Give access only to specific apps/servers, not the whole LAN
• Put anything they need in a DMZ / isolated subnet
• Use SSO + MFA and per-user accounts
• Restrict by device posture if possible (managed laptop, disk encryption, EDR)
• Log access and time-limit accounts
• Avoid broad firewall rules like “allow all from contractor VPN”

Good patterns:

1. ZTNA / app-based access (best)
2. VPN to a restricted subnet
3. Jump box / bastion host for admin work
4. VDI / remote desktop if they need internal tools

Products often used:

• Cloudflare Zero Trust
• Zscaler ZPA
• Tailscale
• Cisco Duo + VPN
• OpenVPN / WireGuard with tight firewall rules

If you want, I can sketch a simple secure contractor setup for a small business or enterprise network.

Replace VPN with a Zero Trust Network Access (ZTNA) setup.

Better model

Instead of giving users access to the whole network, give them access only to specific apps after verifying:

• identity
• device health
• location/risk
• MFA

Good options

• Cloudflare Zero Trust / WARP
• Zscaler Private Access (ZPA)
• Netskope Private Access
• Palo Alto Prisma Access
• Twingate
• For smaller teams: Perimeter 81 or Teleport

Typical replacement architecture

1. SSO + MFA

Use Okta, Microsoft Entra ID, or Ping Identity.

1. Device posture checks

Require managed devices with Microsoft Intune, Jamf, or Workspace ONE.

1. ZTNA connector

Install a lightweight connector inside your network or cloud.

1. App-level access only

Users reach only approved apps, not the whole subnet.

1. Logging + conditional access

Centralize logs in Splunk, Microsoft Sentinel, or Elastic.

If you need broader network replacement

Use SASE:

• Cloudflare One
• Zscaler Zero Trust Exchange
• Netskope SASE

Migration tip

Start with one internal app, move users off VPN in phases, and keep VPN only for edge cases during transition.

If you tell me your environment (Microsoft/Google, on-prem/cloud, team size), I can suggest the best exact stack.

Use a Zero Trust Network Access (ZTNA) / identity-aware access model instead of a broad VPN.

Better pattern:

• SSO + MFA for every app
• Device posture checks (managed device, disk encryption, EDR, OS version)
• Per-app access instead of full network access
• Least privilege and just-in-time access
• Microsegmentation inside the network
• Conditional access based on user, device, location, risk

Common replacements:

• Cloudflare Zero Trust
• Zscaler Private Access (ZPA)
• Twingate
• Google BeyondCorp / IAP
• Microsoft Entra Private Access

Typical setup:

1. Put apps behind an access proxy / connector.
2. Authenticate users with SSO + MFA.
3. Allow only specific apps, not the whole subnet.
4. Enforce device compliance before access.
5. Log every request.

If you still need remote admin access:

• Use bastion hosts, short-lived credentials, and SSH certificates.
• Avoid exposing internal networks directly.

If you want, I can sketch a VPN replacement architecture for your company size (startup, SMB, or enterprise).

Use a zero-trust, role-based model and make access just-in-time.

Core steps

• Centralize identity with SSO + MFA

Use Okta, Microsoft Entra ID, or JumpCloud.

• Enforce conditional access

Require compliant device, strong MFA, geography/risk checks, and block unknown devices.

• Use least-privilege roles

Give employees only the apps, files, and admin rights needed for their job. Review quarterly.

• Separate admin accounts

Keep a normal user account and a separate privileged account for IT/admin work.

• Use PAM for elevated access

Products like CyberArk, BeyondTrust, or Delinea can grant time-limited admin access.

• Deploy device management

Use Microsoft Intune, Jamf (Mac), or Kandji to enforce encryption, patching, screen lock, and app control.

• Restrict network access

Prefer ZTNA over full VPN with Zscaler ZPA, Cloudflare Zero Trust, or Twingate.

• Limit data exposure

Use file permissions, DLP, and app-level access; avoid shared drives with broad write access.

• Log and review

Send auth and access logs to Splunk, Microsoft Sentinel, or Datadog and alert on privilege changes.

• Automate offboarding

Deprovision access immediately when roles change or employees leave.

Quick policy checklist

• MFA required everywhere
• No shared accounts
• No local admin by default
• Device must be managed and encrypted
• Access granted by role, not request
• Privileged access expires automatically

If you want, I can turn this into a remote-work least-privilege policy template or a recommended stack for small vs. enterprise teams.

Use zero trust + role-based access:

• Define roles first: map each job to only the apps, data, and systems it truly needs.
• Use SSO + MFA everywhere: one identity provider, strong authentication, no shared accounts.
• Grant just-in-time access: elevate permissions only when needed, with approval and expiration.
• Separate admin accounts: keep daily-use accounts non-admin; use privileged accounts only for admin tasks.
• Use device trust: only allow compliant devices (patched, encrypted, managed by MDM).
• Network segment access: don’t give broad VPN access; use app-specific access or ZTNA.
• Apply conditional access: restrict by location, device posture, risk score, and time.
• Review permissions regularly: run quarterly access reviews and auto-remove stale access.
• Log everything: monitor auth, file access, and privilege changes; alert on anomalies.
• Use least-privilege tooling: cloud IAM, PAM, MDM, and DLP to enforce policies.

If you want, I can turn this into a policy template or a step-by-step implementation plan for your company size.

Use a Zero Trust Access model instead of “everyone on the VPN.”

What to do

1. Put an identity layer in front of every app
   • Centralize login with Microsoft Entra ID, Okta, or Google Cloud Identity.
   • Require MFA everywhere; best with phishing-resistant methods like YubiKey or Microsoft Authenticator number matching.
2. Enforce device trust
   • Only allow managed, healthy devices.
   • Use Microsoft Intune, Jamf Pro (Mac), or VMware Workspace ONE.
   • Block access if the device is jailbroken, unencrypted, out of date, or missing EDR.
3. Replace broad VPN with ZTNA
   • Give users access only to specific internal apps, not the whole network.
   • Strong options: Cloudflare Zero Trust, Zscaler Private Access, Palo Alto Prisma Access, or Twingate.
4. Use conditional access
   • Restrict by user, device, location, risk, and app sensitivity.
   • Example: finance apps require managed laptop + MFA + compliant device.
5. Add app-layer protections
   • Put web apps behind a secure access proxy.
   • Use Cloudflare Access, Entra Private Access, or Okta Identity Engine.
   • For legacy apps, publish them through a connector rather than exposing them publicly.
6. Log and monitor everything
   • Send access logs to Microsoft Sentinel, Splunk, or Datadog.
   • Alert on impossible travel, repeated MFA prompts, and unusual geographies.

Simple stack examples

• Microsoft shop: Entra ID + Intune + Defender for Endpoint + Entra Private Access
• Cross-platform SMB: Okta + Jamf/Intune + Twingate
• Enterprise edge focus: Zscaler + Entra/Okta + CrowdStrike

Best-practice rule

If a user, device, or session isn’t trusted, deny by default and grant access only to the exact app needed.

If you want, I can suggest a setup based on your environment (Microsoft, Google, AWS, or mixed).

Use a zero trust approach: don’t trust the network location, trust only verified user + device + app requests. NIST says ZTA is designed for remote users and hybrid work, and CISA recommends using its Zero Trust Maturity Model to plan implementation. (csrc.nist.gov)

Best-practice pattern

1. Put apps behind identity-aware access, not broad network VPN access. CISA’s guidance on modern secure network access favors zero trust / SASE / ZTNA-style access to apps and services. (cisa.gov)
2. Require phishing-resistant MFA for every app and admin account. CISA says businesses should aim for phishing-resistant MFA; NIST says verifiers should offer phishing-resistant options, and cryptographic authenticators with non-exportable keys provide phishing resistance. (cisa.gov)
3. Check device posture before granting access: managed device, patched OS, disk encryption, EDR present, no risky jailbreak/root, etc. NIST’s ZTA model explicitly uses subject and device authentication/authorization before a session is established. (csrc.nist.gov)
4. Grant least privilege per app and per request. NIST and CISA both describe zero trust as minimizing implicit trust and using granular, per-request access decisions. (nist.gov)
5. Segment by application, not by flat network. NIST’s guidance for cloud-native and hybrid environments emphasizes app/service identities and granular application-level policy enforcement. (csrc.nist.gov)
6. Log, monitor, and re-evaluate continuously so access can be revoked when risk changes. (nist.gov)

Simple rollout order

• Centralize identity in an IdP/SSO.
• Turn on phishing-resistant MFA.
• Inventory internal apps and classify sensitivity.
• Put the highest-risk apps behind ZTNA first.
• Add device compliance checks.
• Replace “network access” with “app access” wherever possible.
• Review logs and access grants continuously. (csrc.nist.gov)
