Array ZTAG Series Zero Trust vs Firezone: Side-by-Side Comparison (2026)

Array ZTAG Series Zero Trust

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.

Firezone

Teams standardizing on WireGuard for faster VPN performance while enforcing zero-trust access controls should start with Firezone; the open-source foundation means you're not locked into a vendor's encryption implementation, and the hole-punching architecture actually hides resources from the internet rather than just gating them. WireGuard's 3-4x speed advantage over OpenVPN matters in practice for developers and remote workers who won't tolerate latency, and the policy engine handles conditional access (location, time of day, device posture via IdP) without the complexity of legacy ZTNA appliances. Skip this if you need deep integration with on-premises Active Directory forests or require vendor-backed compliance attestations; a 10-person startup selling to enterprises will struggle with the latter.
