Zero Trust Agent Identity Pipeline
Zero-trust AI agent identity architecture with JWT validation, scoped OBO token exchange, SPIFFE/SVID workload identity, and MCP tool authorization.
Risk-Tiered Human-in-the-Loop
Human-in-the-loop approval architecture that scores agent actions by risk, routes high-risk requests for review, and writes immutable audit records.
