Features, pricing, ratings, and pros and cons, compared head to head.
Allentis Network Diode (Tapics) is a commercial ot network segmentation tool by Allentis. Array ZTAG Series Zero Trust is a commercial zero trust network access tool by Array Networks. Compare features, ratings, integrations, and community reviews side by side to find the best ot network segmentation fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, 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.
