Best ZTNA Tools in 2026: 6 Zero Trust Network Access Platforms
Open an application by identity, then expire the session. Dumping a user onto 10.0.0.0/8 rebuilds a VPN.
Expertise: Network Security · Level: Intermediate · 6 min read
The client still dumps the user on 10.0.0.0/8. That is a subnet, not zero trust network access. The VPN the team already runs is green: people connect, tickets drop.
Green on a tunnel is false confidence. ZTNA is an application you open, with a policy on the identity and the device, then a session that expires. Skip expire and you rebuilt a VPN with a new logo.
What happens in production is a contractor who reaches every printer VLAN because the group mapped to a CIDR. Privileged admin expiry is a different clock. This shortlist is the app-level path.
Cloud ZTNA brokers, self-hosted access proxies, and the identity platform that already issues the device claim split the buy. Pick the one that never hands out the whole network.
How we evaluated
We read first-party docs, source, licenses, and release notes, and we treat a marketing page as a claim, not as proof that two products do the same work.
We cared about whether the product opens an app rather than a subnet, whether you operate the connector, whether identity is the policy, and whether the docs name an application you can put in front of a host you own.
We read first-party docs, licenses, and release notes. Unless a write-up says otherwise, we did not run a paid tenant.
| Tool | Best for | What to check |
|---|---|---|
| Pomerium | Identity-aware proxy you host | Policy on the route · Apache-2.0 · you host the proxy |
| Tailscale | WireGuard mesh with identity | WireGuard plus identity · BSD clients / commercial control · ACLs are the control |
| Cloudflare Access | Known identity-aware edge | IdP policies · Cloudflare Zero Trust plans · same edge as Cloudflare |
| Twingate | Commercial connector ZTNA | Connectors · commercial · IdP in front |
| Zscaler Private Access | Known enterprise ZTNA | Brokered app access · commercial · enterprise IdP |
| Teleport | Cert plane that can replace a jump box | Short certs · AGPL-3.0 / commercial · SSH and Kubernetes path |
Pomerium
Best for identity-aware proxy you host
Pomerium is also on the PAM list as a web-admin proxy. Here it is the ZTNA-shaped path.
Policy sits on the route. The identity provider sits in front. You host it. Apache-2.0 is the license. It is not a global SASE point-of-presence story.
Key features
- Policy on the route
- IdP in front
- Self-host
- Apache-2.0
Why we like it
A proxy you already would have run, with identity on the URL, is the open path to one app.
Limits
You operate it. Not a global SASE PoP story.
Tailscale
Best for WireGuard mesh with identity
Tailscale is a WireGuard mesh. Identity from your IdP. People run it because it works. The control plane is their SaaS unless you self-host Headscale.
Treat ACLs as the ZTNA, not the happy LAN. A mesh can still be too flat if ACLs are allow-all. Headscale is a different ops job.
Key features
- WireGuard
- IdP-based nodes
- ACLs
- Headscale as a self-host cousin
Why we like it
The mesh already in the building is the starting point. The buy is whether ACLs name the app.
Limits
Allow-all ACLs are a LAN. Headscale is a different ops job.
Cloudflare Access
Best for known identity-aware edge
Access puts an IdP in front of an origin. Same edge as the WAF list.
If DNS is already Cloudflare, start here. Plan SKUs apply. It is not a PAM vault. If the job is the filter, open WAF.
Key features
- IdP policies
- Same edge as Cloudflare
- Tunnel option
- Plan-gated
Why we like it
Identity on the edge you already use for DNS is the no-new-PoP row.
Limits
Plan SKUs. Not a PAM vault. If the job is the filter, open WAF.
Twingate
Best for commercial connector ZTNA
Twingate deploys connectors next to the app. Users get the app, not the subnet, if you configure it that way.
Commercial option when you will not host Pomerium. Configuration still decides whether the path is flat.
Key features
- Connectors
- IdP
- Split access on the public docs
- Commercial
Why we like it
A connector next to the app is the commercial shape of one name, not a /16.
Limits
Commercial. You still configure split access.
Zscaler Private Access
Best for known enterprise ZTNA
Zscaler Private Access is the known enterprise name. Often bought with the Zscaler stack.
Steering-committee option. It is not Tailscale. Same family as their internet access product.
Key features
- Brokered app access
- Enterprise IdP
- Same family as ZIA
- Sales-led
Why we like it
The broker a steering committee already wrote down is the known enterprise path.
Limits
Commercial. Not a mesh you host.
Teleport
Best for cert plane that can replace a jump box
Teleport is on the PAM list. Here it is the path to SSH and Kubernetes without a standing VPN.
If the app is SSH, this is ZTNA with a privileged flavor. Overlap is declared. AGPL on the core. Enterprise is paid. You still need an IdP.
Key features
- Short certs
- App and K8s access
- Audit
- Self-host or cloud
Why we like it
A cert to the name you meant is the path when the old answer was a jump box on a flat net.
Limits
AGPL core. Enterprise paid. Still need an IdP.
What we left out
- Google BeyondCorp Enterprise. Teams already on Google Workspace want the first-party path. Cloudflare Access already covers the known identity-aware edge, and this page is not a second cloud console.
- Netskope Private Access. SASE RFPs already print a second enterprise broker. Zscaler Private Access already covers that enterprise ZTNA option.
Tailscale threads treat identity on the mesh as the reason to drop a flat VPN. Read the ACL warnings in those threads too.
Questions before you buy
If procurement cannot get written answers, you are still buying a brochure.
- Can this user reach only the app I named, or do they land on a subnet?
- Do we operate the proxy, or are we buying a global broker we cannot dump?
- Are we buying a path, a privileged session, or both, and which one is already paid for?
Open the app. If the product is still a tunnel to a flat network, call it a VPN.
FAQs
Does ZTNA replace PAM?
No. ZTNA is the path. PAM expires the admin. Some products do both. The job is still two questions.
Is Tailscale ZTNA if ACLs are open?
No. That is a mesh LAN. The control is the ACL.
Does this replace the WAF?
No. WAF filters the public edge. ZTNA hides the app.
Is this a scored bake-off?
No. Order is editorial.
