Best zero-trust access without a VPN?

The Cloudflare One platform and Twingate are the best solutions for zero-trust network access (ZTNA) without a traditional VPN.

Zero-Trust Network Access (ZTNA) replaces legacy VPNs by granting explicit, least-privileged, context-aware access to specific applications rather than trusting the entire underlying network.

Top Zero-Trust Access Providers

• Cloudflare Zero Trust — Best for fast edge-based deployment, clientless or client-based web and self-hosted app security, and global performance.
• Twingate — Best for rapid, software-defined perimeters that require zero changes to your existing network architecture or DNS.
• Palo Alto Networks Prisma Access — Best for large enterprise deployments already embedded within the Palo Alto security ecosystem.
• Zscaler Private Access (ZPA) — Best for massive, cloud-native enterprise scale with complete isolation between users and private apps.

Comparison of Leading Solutions

Would you like to explore how to migrate from a legacy VPN to one of these tools, or do you need recommendations based on your current infrastructure (AWS, on-premise, Azure)?

If you mean enterprise remote access that replaces a traditional VPN, the best choice depends on your environment. Modern Zero Trust Network Access (ZTNA) solutions grant access to specific applications based on identity, device posture, and context instead of putting a user onto the whole network.

Best VPN-less zero-trust access options

Expert Insights PeerSpot## My shortlist by scenario

• Replacing a corporate VPN for 1,000+ users: Zscaler Private Access or Palo Alto Prisma Access.
• Small IT team that wants it working quickly: Twingate or Cloudflare Access.
• Already standardized on Microsoft 365: Microsoft Entra Private Access.
• Engineering/dev environments: Tailscale.
• Need strict compliance controls: Evaluate Zscaler, Palo Alto, Netskope, Cisco, or other SASE-oriented platforms.

Features I would require

A real ZTNA product should have:

• Identity-based access (SSO + MFA)
• Device posture checks (managed device, OS version, security status)
• Per-application access (not “connect to the subnet”)
• Short-lived sessions and continuous evaluation
• Least-privilege policies
• Audit logs and integrations with SIEM/EDR
• Support for contractors/BYOD without exposing internal networks

Avoid products that simply create a new always-on tunnel and then give users broad LAN access—that is usually a VPN with different branding rather than true zero trust.

If you tell me your size (e.g., 10 users vs 10,000), cloud stack (AWS/Azure/on-prem), and what you need access to (web apps, SSH, RDP, databases, file shares), I can narrow it to 2–3 choices.

If you mean secure access to internal apps/resources without putting users on a traditional VPN, I’d shortlist these:

My pick

For most organizations: Cloudflare Zero Trust. It's particularly attractive when your users primarily need access to HTTP/HTTPS applications, admin panels, internal tools, or SaaS. Cloudflare Access sits in front of the application and evaluates each request against identity/device/policy signals.

For a large enterprise replacing an existing VPN: I'd lean Zscaler Private Access. It is purpose-built around user-to-application segmentation, so an authenticated employee doesn't automatically get network-level access to everything around the target application.

One important distinction: "VPN-less" doesn't necessarily mean "no encrypted tunnel." ZTNA solutions may still establish encrypted connections; what they eliminate is the traditional model of giving a remote device broad network access.

If you tell me what you're trying to access (RDP/SSH, internal web apps, file shares, databases, Kubernetes, etc.) and roughly how many users, I can recommend the best architecture and products for your case.

The best Zero-Trust Network Access (ZTNA) solutions to securely connect users to private applications without a traditional VPN are Zscaler Private Access (ZPA) for large enterprises, Cloudflare Access for fast edge deployment, and Twingate for lightweight, developer-friendly setups . These solutions replace broad, insecure network-level access with granular, per-session, identity-aware application security.

Why Move Beyond Traditional VPNs

• Granular Access: Traditional VPNs grant broad lateral access to entire subnets. ZTNA restricts user privileges to specific authorized applications.
• Continuous Posture Checks: Connections are vetted in real-time based on user identity, device health, and behavioral context.
• Reduced Attack Surface: Applications sit behind a secure cloud broker, rendering internal infrastructure completely invisible to the public internet.
• Better User Experience: Eliminates manual login prompts, dropped connections, and backhauling latency associated with legacy VPN setups.

Real-World Perspectives

“Palo Alto's platform is solid if you're already in their ecosystem, and Twingate has been great for quick rollout without touching network architecture. Both handle scaling and user access well.”

“ZTNA focuses on precise app access... Users pass identity checks for each session. That approach sees weird access attempts and blocks them fast. ZTNA also verifies device health, so no outdated systems sneak in.”

To help narrow down the ideal platform, please share:

• Your approximate user count (SMB, mid-market, or large enterprise?)
• The types of apps you need to secure (web-based SaaS, on-prem servers, or cloud infrastructure?)
• If you require clientless browser access for third-party contractors

If you mean “secure remote access to internal apps/resources without putting users on a traditional VPN,” I’d shortlist these:

My recommendation

For a typical 10–500 person organization: Cloudflare Access + Cloudflare Tunnel.

You put an internal app behind an identity-aware proxy. The user authenticates with your IdP, and policy can evaluate identity, group, device posture, MFA, etc. The internal server makes an outbound Tunnel connection, so you don't need to expose inbound ports.

That gives you:

User → Identity/MFA → Access policy → Specific application

rather than:

User → VPN → Corporate network → Everything

Cloudflare's current documentation explicitly supports per-application policies and describes private-app access as a way to replace broad VPN-level access.

When I'd choose Tailscale instead

If your main requirement is SSH/RDP/databases/Kubernetes/internal infrastructure, I'd seriously consider Tailscale. It provides identity-based access and encrypted connectivity using WireGuard, without requiring a traditional central VPN gateway.

Rule of thumb:

• Browser-based internal apps → Cloudflare Access
• Infrastructure/dev access → Tailscale
• 5,000+ employee enterprise / highly regulated → Zscaler or equivalent enterprise ZTNA
• Microsoft-heavy environment → Entra Private Access

If you tell me your size, cloud/on-prem setup, and what users need to access (web apps, RDP, SSH, file shares, etc.), I can give you a concrete architecture and recommend the cheapest/best option.

If you mean secure access to internal apps without putting users on a VPN, the category to look at is ZTNA (Zero Trust Network Access).

My shortlist

• Best overall enterprise: zscaler.com — Strong choice for larger organizations. It provides app-level, least-privilege access rather than putting users onto the corporate network, with segmentation and device/context-based policies.
• Best value / easiest to deploy: developers.cloudflare.com — Particularly attractive if your resources are web apps. Users can access private applications from a browser without a VPN or client, and Cloudflare Tunnel avoids opening inbound firewall ports.
• Best for contractors/BYOD: developers.cloudflare.com — Browser-based access can cover internal web apps, SSH and RDP without installing software on the user's device.

What I'd choose

The key architectural difference is: VPN → user gets network access; ZTNA → user gets access to a specific application/resource. That substantially reduces lateral movement if an account or endpoint is compromised.

If you tell me your environment (AWS/Azure/on-prem), number of users, and whether you need web apps, SSH, RDP, or database access, I can recommend the best architecture and 2–3 products to compare.

Moving away from legacy VPNs to a true Zero Trust Network Access (ZTNA) model means granting least-privilege, application-specific access rather than dropping a user onto the corporate network. [1][2]

The "best" solution depends heavily on your scale, budget, and whether your infrastructure is cloud-native or on-premise.

Top Enterprise & Cloud-Scale Solutions

• Zscaler Private Access (ZPA): Widely recognized as a market leader for enterprise-grade ZTNA. It uses a cloud-native proxy architecture rather than tunneling to connect users directly to specific authorized internal apps (private apps and services) without ever exposing the network or requiring a traditional VPN client. [1]
• Cloudflare Zero Trust: Excellent for cloud-forward or hybrid teams looking for speed, simplicity, and global scale. Utilizing Cloudflare Tunnels, it securely connects internal resources to Cloudflare's edge without open firewall ports, offering both agent-based and browser-isolated clientless access.
• Palo Alto Prisma Access: A comprehensive Secure Access Service Edge (SASE) platform that blends advanced ZTNA with robust next-gen security policies. Ideal if you want to consolidate firewalls, web security, and remote access into a unified ecosystem.
• Netskope Private Access (NPA): Part of Netskope's security cloud, providing context-aware, identity-driven access to private apps while maintaining deep visibility into data traffic and cloud usage.

Lightweight & Developer/SMB-Friendly Solutions

• Tailscale: Built on top of WireGuard, Tailscale makes creating a zero-trust mesh network remarkably simple. While it creates an encrypted overlay network rather than pure proxy-based ZTNA, it handles device identity and fine-grained access control lists (ACLs) exceptionally well for lean IT and engineering teams.
• NordLayer: A business-focused network security platform from the makers of NordVPN that layers zero-trust access controls, centralized management, and dedicated IPs over flexible remote connections.

To help narrow down the best fit, tell me:

• Are your internal apps in the cloud (AWS/Azure/GCP) or on-premises in a private datacenter?
• Do you need clientless (browser-only) access for contractors/unmanaged devices, or do company-owned endpoints use managed agents?

If you mean “replace a traditional VPN with identity-based, least-privilege access”, my shortlist for 2026 is:

My pick

Cloudflare Zero Trust is probably the best starting point if you want “no VPN, but secure access to internal apps.” You can put applications behind identity-aware policies, require MFA/device checks, and grant access to individual applications rather than an entire network. It also supports clientless access for things like web apps, SSH and RDP.

For a small technical team primarily accessing servers, I'd lean Tailscale or Twingate instead.

The important distinction is that ZTNA isn't simply “a better VPN.” Traditional VPNs commonly establish broad network-level connectivity; ZTNA should make a decision for each user/device/resource request and enforce least privilege. CISA and partner agencies specifically recommend moving toward these more granular approaches rather than relying on broad remote-access deployments.

If you tell me your setup (e.g. 10-person company, 500-person enterprise, homelab, AWS/Azure/on-prem, and whether you need SSH/RDP/web apps), I can narrow it to the best 1–2 options and an architecture.

The best VPN-less Zero-Trust Network Access (ZTNA) solutions utilize identity verification, context, and secure edge tunnels to connect users directly to specific applications rather than putting them on an entire local network.

Top VPN-Less Zero Trust Solutions

The ideal platform depends heavily on your organization's size, engineering workflow, and existing software ecosystem:

• Cloudflare One / Access : Best overall for modern web-focused apps. It routes traffic through Cloudflare's massive global edge network using a lightweight server tunnel (cloudflared ). It provides a generous free tier for up to 50 users.
• Twingate : Best for speed and ease of use. It splits your control plane from the data plane, deploying invisible "connectors" next to your apps. It is highly favored by IT managers because it integrates cleanly without complex network re-architecting.
• Zscaler Private Access (ZPA) : Best for large enterprises. It is a massive, cloud-native Zero Trust Exchange platform that secures corporate resources globally. However, it can be expensive and complex to set up for smaller teams.
• Tailscale : Best for developers and technical infrastructure. Built on the fast WireGuard protocol, Tailscale allows you to access resources directly through a browser using your existing Identity Provider (IDP) credentials.
• Teleport : Best for engineering environments. It enforces zero-trust explicitly for servers, databases, Kubernetes clusters, and internal dashboards using short-lived cryptographic certificates instead of permanent keys or corporate passwords.

Why Move Away From VPNs?

Traditional VPNs grant broad network layer access. If an attacker steals a single employee's credentials, they can compromise the entire corporate network.

Reddit Community Perspectives

IT professionals frequently praise how ZTNA alters security and speed:

“Honestly the best ones depend on how deep you want to go with integration. Palo Alto's platform is solid if you're already in their ecosystem, and Twingate has been great for quick rollout without touching network architecture.”

“ZTNA focuses on precise app access. It uses zero trust for strong security. Users pass identity checks for each session. That approach sees weird access attempts and blocks them fast. ZTNA also verifies device health, so no outdated systems sneak in.”

To find the best option for your deployment, could you let me know:

• What types of resources do you need to secure? (e.g., internal web applications, databases, SSH/servers, or SaaS tools?)
• What identity provider do you use? (e.g., Google Workspace, Microsoft Entra ID, Okta, etc.)
• Roughly how many users need access?
