Product Overview

SPIFFE / SPIRE

SPIFFE (Secure Production Identity Framework For Everyone) is a CNCF-graduated open standard for workload identity, and SPIRE is the reference implementation. Instead of giving workloads shared secrets, SPIRE issues short-lived, cryptographically verifiable identities (SVIDs) to each service, using attestation (where is this workload running, what image, what namespace) to prove who it is. SPIFFE is the foundation for zero-trust service-to-service authentication at companies like Bloomberg, Uber, and Square.
