CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market security teams protecting critical infrastructure should buy Dispel Zero Trust Engine specifically for OT environments where traditional zero trust tools fail, because it speaks 65,000+ protocols including proprietary industrial systems that off-the-shelf PAM can't touch. The platform's hybrid deployment model and native support for IEC 62443 and NERC CIP mean you're not retrofitting generic access controls onto your OT network. Skip this if your priority is IT-only remote access or if you need a single pane of glass for both corporate and industrial assets; Dispel's OT focus means it won't be your answer for general workforce access management.
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.
