Security incident on record — Thanksgiving 2023 — nation-state actor used stolen Okta tokens to access internal Atlassian/Jira; no customer data affected
▪ Editorial verdict
Cloudflare Zero Trust consistently receives the best end-user experience ratings in the ZTNA category. The lightweight WARP client, Cloudflare's 300 plus PoP global edge for minimal latency, and the free tier for up to 50 users make it the most accessible enterprise ZTNA available. The Thanksgiving 2023 nation-state attack on Cloudflare's own systems, contained through their own Zero Trust implementation, demonstrated the product in practice under real adversarial conditions.
The device posture integration breadth is less than Zscaler, and the legacy thick-client application support for complex on-premises apps is less mature. The 2023 incident also highlighted dependency risk on the identity provider credential chain.
The verdict: Cloudflare Zero Trust is right for organisations of any size wanting the best user experience, the lowest deployment friction, and transparent pricing with a free tier. Large enterprises with complex legacy application estates or the most demanding device posture requirements should evaluate Zscaler ZPA.

PROTECTIONStrong
App-level access control
4 / 5
Cloudflare Tunnel exposes specific applications via the Cloudflare edge — origin servers are never directly reachable. Scored 4 because the model is excellent for web/HTTP apps but TCP/UDP application support is more complex.

4 / 5
WARP client collects device posture signals. Scored 4 because posture signal depth is good but less comprehensive than Zscaler for enterprise MDM/EDR integration scenarios.
