CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams managing post-breach containment and lateral movement at scale should choose Illumio Insights for its AI-driven microsegmentation that actually stops propagation, not just logs it. The platform maps continuous network traffic and enforces least-privilege policies across hybrid infrastructure, with documented strength in RS.MI (incident mitigation) and DE.CM (continuous monitoring) under NIST CSF 2.0. Skip this if you need EDR or endpoint visibility; Illumio operates at the network layer and assumes you already know what's moving across your segments.
Mid-market and enterprise teams replacing VPN will find Fortra ZTNA's strongest value in its hybrid deployment flexibility and granular access controls that actually enforce least-privilege without admin headaches. The platform covers all four critical NIST CSF 2.0 areas for identity and continuous monitoring, which matters because most ZTNA products punt on asset inventory or detection tuning. Skip this if your org needs deep integration with legacy on-premises identity systems or runs exclusively on-prem; Fortra's strength is in hybrid environments where cloud and datacenter access requirements overlap.
