The Best Zero Trust Platforms in 2026

Zero trust is a badly abused phrase. Stripped of the marketing it means one thing: no device or user is trusted because of where it sits on the network.

Every request is authenticated and authorised on its own merits, every time.

In practice that translates into a product category, zero trust network access, that does the job the corporate VPN used to do and does it per application instead of per network.

The difference matters on the day something goes wrong. A VPN puts an attacker who steals one laptop on the same flat network as your finance systems. A zero trust platform puts them in front of the same login prompt as everyone else, for the one application that laptop was allowed to reach.

A zero trust network access platform sits between your people and your internal applications.

Instead of granting network access, it brokers each connection: it checks identity against your directory, checks the device against a posture policy, then proxies the single application the policy allows, and logs the whole thing.

The connector model is what makes it deployable.

A lightweight agent inside your network dials out to the provider, so nothing has to be exposed to the internet and you can retire inbound firewall rules rather than add to them.

The VPN model fails in a specific and repeatable way. It authenticates once, at the perimeter, and then trusts everything behind it.

That is why a single set of stolen credentials so often turns into lateral movement across an entire estate, and why breach write-ups keep describing the same shape of incident.

There is also a duller reason, and it is the one that usually funds the project: auditors ask who reached which system and when.

A VPN can tell you someone connected. A zero trust platform can tell you which application they opened, from which device, and whether that device was patched at the time.

Four of the five publish a per-user list price. Cloudflare One is free up to 50 users, then Pay-as-you-go at $7/user/mo. Tailscale Personal is free for up to 6 users, then Standard costs the same per seat as NordLayer Lite. Twingate Starter is free for up to 5 users, and Teams is $5/user/mo billed yearly or $12 month to month.

NordLayer has no free tier: Lite is $8/user/mo, Core $11/user/mo and Premium $14/user/mo. Check Point SASE, formerly Perimeter 81, is quote-only. Those tiers share a 5-user minimum and 6 devices per licence, yearly billing discounts the monthly rate, and a $40-a-month dedicated IP server is required on Core and Premium.

Costs jump from Lite to Premium, at the 5-user minimum for a smaller team, and when gateway fees sit on top of a seat price.
