What SPIFFE Project does

SPIFFE Project (Secure Production Identity Framework for Everyone) is a CNCF-governed open-source project founded in 2016 that defines a vendor-neutral framework for issuing cryptographic identities to workloads running across heterogeneous infrastructure. The project specifies the SPIFFE ID (a URI-format identity), SVIDs (SPIFFE Verifiable Identity Documents — short-lived X.509 certificates or JWT tokens with automatic rotation), the Workload API (a gRPC interface for retrieving identities at runtime), Federation (cross-organization trust exchange), and the Broker API (for infrastructure components acting on behalf of workloads). SPIRE (SPIFFE Runtime Environment) is the project's reference implementation, providing node and workload attestation across Kubernetes, virtual machines, bare metal, and (experimentally) Windows and serverless environments. SPIFFE holds CNCF graduate status and is licensed under Apache 2.0; it generates no commercial revenue and is maintained by community contributors from organizations including Amazon, Google, IBM, Red Hat, and Uber. The project reports adoption by 23+ named enterprises spanning technology, financial services, healthcare, and energy — Amazon, Google, IBM, Netflix, Uber, Bloomberg, SAP, Cisco, VMware, Intel, HPE, Yahoo, Twilio, HashiCorp, Arm, Unity, Indeed, Wise, Anthem, and Duke Energy among them. Distribution is fully self-serve via GitHub releases, GitHub Container Registry, and hardened Helm charts; go-to-market is community-led through documentation, the "Solving the Bottom Turtle" book, semi-annual Community Days, Slack, and GitHub rather than through any commercial sales motion.

Revenue model

1. Open Source Software Distribution: SPIFFE and SPIRE are open-source projects distributed freely under Apache License 2.0. No revenue is generated directly from the software. Commercial vendors (Red Hat, Teleport, Greymatter.io, Venafi, AWS, GCP) build and sell commercial products that implement or are based on the SPIFFE standard.

Core offering

SPIFFE is an open-source specification and framework that provides strongly attested, short-lived cryptographic identities (SVIDs) to workloads across heterogeneous infrastructure including Kubernetes, VMs, bare metal, and serverless environments. SPIRE is the reference implementation toolchain that issues X.509-SVIDs and JWT-SVIDs via the SPIFFE Workload API and supports cross-organization trust through SPIFFE Federation. The project is distributed under Apache License 2.0 as a CNCF graduated project.

Product overview

SPIFFE (Secure Production Identity Framework for Everyone) is an open-source specification and CNCF graduated project providing a universal identity control plane for distributed systems. The portfolio consists of SPIFFE (the specification framework defining cryptographic identity standards including SPIFFE IDs, SVIDs, and trust domains), SPIRE (the reference implementation providing APIs and toolchain for establishing workload trust across Kubernetes, VMs, bare metal, and serverless), SPIFFE Workload API (gRPC-based API for workload identity retrieval), SPIFFE Broker API (for infrastructure components acting on behalf of workloads), and SPIFFE Federation (cross-organization trust establishment). The ecosystem includes hardened Helm charts for Kubernetes deployment and educational materials like the Solving the Bottom Turtle book.
