CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise and mid-market security teams deploying multi-agent AI systems need CloudMatos Aegis Gateway because it's the only runtime control point that actually stops agent actions before they happen, not after; parameter-level API access control and sub-20ms policy evaluation mean you can enforce governance at the speed agents operate. The tool covers all five NIST CSF 2.0 categories across access control, data protection, and continuous monitoring, with immutable audit logs that satisfy compliance requirements without friction. Skip this if your AI systems are still single-agent or if you're looking for a detection-only solution; Aegis Gateway is built for enforcement, not visibility.
Teams deploying AI coding agents at scale need visibility into what those models are actually doing, and Oso is built specifically for that job rather than retrofitting general security tools. It covers the full cycle: PR.AA controls around agent access, DE.CM continuous monitoring of agent behavior, and RS.AN incident analysis when things go wrong. Skip this if your AI footprint is experimental or single-use; Oso assumes you're running agents in production where audit trails and control enforcement matter.
