Zero Trust through Verifiable Identity, for People and Workloads
See how Greymatter attests workloads, verifies people, carries the person across the hops the mesh controls, and records it without a credential anyone can replay.
Zero Trust starts with one question: who is this?
The answer has two halves. The workload must prove what it is. The person behind the request must stay known on later hops. Most programs solve only one half. Headers such as x-user-id fill the gap, and any caller can set them.
Greymatter closes the gap. SPIFFE and SPIRE give mesh workloads an identity that the platform attests and rotates. Greymatter verifies the person at the edge with the program’s own identity provider or smartcard infrastructure. The data planes then carry that person over mutual TLS.
Trust comes from cryptographically verifiable identity, not network location, for workloads and for people.
The central point
- Why a header such as x-user-id is where attribution fails.
- How SPIFFE and SPIRE attest and rotate workload identity.
- How Greymatter carries a verified person across the hops the mesh controls.
- How an auditor follows one session from sign-in to last use without seeing a replayable value.
