Permiso Identity Security vs PlainID Identity Security: Side-by-Side Comparison (2026)

Permiso Identity Security

Teams managing AI workloads across multiple cloud environments need Permiso Identity Security because it's the only platform that treats AI agents as first-class identity threats alongside human users and service accounts. The Universal Identity Graph spans IaaS, SaaS, and identity providers while flagging shadow AI activity and prompt manipulation attacks that traditional ITDR tools completely miss. This is less relevant for organizations still in early AI adoption or those wanting a lightweight identity governance tool; Permiso requires active threat hunting to justify its cost.

PlainID Identity Security

Mid-market and enterprise teams managing SaaS sprawl will get real value from PlainID Identity Security because it maps identity-to-asset connections across applications and APIs without requiring you to manually inventory access, then enforces policy dynamically based on risk. The platform covers PR.AA and ID.AM in NIST CSF 2.0, meaning it finds over-provisioned users and builds reusable policy blocks that actually stick across your tech stack instead of drifting. Skip this if you need forensic identity analytics or attack chain reconstruction; PlainID prioritizes discovery and ongoing hygiene over incident response depth.
