Tailscale is a commercial zero trust network access tool by Tailscale. Cato Networks ZTNA is a commercial zero trust network access tool by Cato Networks. Compare features, ratings, integrations, and community reviews side by side to find the best zero trust network access fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams replacing bastion hosts and VPN infrastructure with zero trust network access should pick Tailscale for its WireGuard mesh that eliminates inbound firewall rules entirely, letting you enforce identity-based policies without managing jump servers or exposed infrastructure. The platform maps cleanly to NIST PR.AA and PR.IR, particularly for organizations building multi-cloud environments where traditional perimeter security becomes liability rather than asset. Skip this if you need granular application-layer inspection or deep packet analysis; Tailscale is network-layer connectivity, not a proxy or firewall replacement.
Mid-market and enterprise teams replacing legacy VPN with zero trust will prefer Cato Networks ZTNA for its cloud-native architecture that eliminates the need to manage on-premises infrastructure while enforcing identity-based access across hybrid IT. The platform covers both NIST PR.AA (identity and access control) and PR.IR (infrastructure resilience), meaning you get access policy enforcement without sacrificing visibility into whether your security perimeter actually holds under load. Skip this if your organization runs primarily on-premises and needs deep microsegmentation of internal networks; Cato shines at securing remote access to distributed resources, not re-architecting the datacenter.
