Agent identity & access

SPIRE (SPIFFE Runtime Environment)

A CNCF graduated open-source toolchain that attests running workloads and issues them short-lived SPIFFE identities (X.509 and JWT SVIDs) through the Workload API, enabling mutual TLS and authentication to secret stores, databases and cloud services. It provides identity plumbing, not agent inventory or governance workflows.

Ask for a demonstration

Demonstrate a Kubernetes workload attesting to SPIRE, receiving a rotating X.509 SVID, and using it for mTLS to another service across a federated trust domain.

Capabilities and evidence

Support labels reflect the supplied research. Documentation and vendor claims are not independent product tests. “Not established” means the researcher did not find support; it does not prove a capability is absent.

Documented by provider

SPIRE exposes the SPIFFE Workload API to attest running software systems and issue them SPIFFE IDs and SVIDs, enabling mTLS or signed JWT authentication between workloads.

Limit: Repository README does not address AI-agent-specific governance, inventory or approval workflows.

Documented by provider

SPIRE is maintained by the SPIFFE community and is a graduated project of the Cloud Native Computing Foundation.

Limit: Graduation status does not imply enterprise support or SLAs.

Documented by provider

SPIFFE specifications define short-lived cryptographic identity documents (SVIDs) issued via a simple API across heterogeneous environments and organizational boundaries.

Limit: Specification-level description; implementation coverage varies by SPIFFE implementation.
