CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Engineering teams building microservices or API-first architectures need Ory Keto if they're tired of baking authorization logic into every service, since it decouples access control as a dedicated layer that enforces policies at sub-10ms latency across distributed systems. The Google Zanzibar architecture means you get strong consistency guarantees that most homegrown RBAC systems lack, and the gRPC API lets you call it directly from services without HTTP overhead. Skip this if you need a UI-driven identity governance platform for compliance audits or you're still running monoliths where pushing authorization calls across the network adds unacceptable latency; Keto is built for teams willing to shift left on policy architecture.
