PlainID Identity Security vs Silverfort AI Agent Security: Side-by-Side Comparison (2026)

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.

Silverfort AI Agent Security

Mid-market and enterprise security teams drowning in unmanaged AI agents across their identity stack should start here; Silverfort AI Agent Security finds and controls what you don't know exists, which is the only real problem in this category. The platform maps agents to human owners through visual workflows and enforces least privilege through real-time MCP gateway inspection, covering NIST ID.AM and PR.AA where most identity tools go silent. Skip this if your organization has fewer than 50 employees or hasn't yet standardized on a single IdP; the discovery value collapses without scale and integration breadth.
