Definition

SPIFFE (Secure Production Identity Framework for Everyone) is an open standard that defines a framework for securely identifying and authenticating services in dynamic and heterogeneous environments. It provides a way to issue, manage, and validate cryptographic identities to services, enabling secure communication without relying on network-based security controls. SPIFFE is particularly useful in cloud-native environments where services are ephemeral and distributed across multiple platforms.
