Active Directory Permissions Analyzer vs Ory Keto: Side-by-Side Comparison (2026)

Short answer

Security teams managing Active Directory at mid-market to enterprise scale should pick Active Directory Permissions Analyzer when permission creep and orphaned access rights are eating your audit time. It runs agentless and requires no admin rights to surface domain-wide ACL visibility across custom schema classes and extended rights, meaning you audit without operational friction. Skip this if your organization hasn't standardized on Active Directory as your primary identity store or if you need real-time enforcement alongside analysis; this tool is audit-first, not remediation-focused. 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.
