Array ZTAG Series Zero Trust is a commercial zero trust network access tool by Array Networks. Tailscale is a commercial zero trust network access tool by Tailscale. Compare features, ratings, integrations, and community reviews side by side to find the best zero trust network access fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams enforcing identity-first network access will benefit most from Array ZTAG Series Zero Trust because Single Packet Authorization eliminates the attack surface of traditional VPNs, requiring zero network visibility before authentication. The tool validates device posture, OS patches, and connection reputation continuously alongside MFA and SSO, addressing NIST PR.AA access control and PR.IR resilience in tandem. Skip this if your priority is detection and incident response rather than access prevention; ZTAG is built to shrink the perimeter, not hunt what gets inside it.
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.
