What role can SPIFFE or SVIDs play in agent workload identity?

SPIFFE provides a standard way to identify software workloads, and SVIDs are the verifiable identity documents used in that model. In an AI agent architecture, this can give each agent, service, or tool a distinct workload identity instead of relying on shared credentials. That identity can then be used for mTLS, authorization policy, and audit logs. For enterprises, the value is consistency: agents can be treated as production workloads with identities that can be issued, validated, and rotated. Diagrid positions SPIFFE-based identity as part of Catalyst's zero-trust approach for agents and MCP servers.
