No proof, no access.
People, outside systems, and workloads each prove themselves differently. Greymatter holds all three to one standard.
One breach stays one breach.
Attackers who get in usually spread by posing as one of your own apps. With Greymatter, no app can pose as another. With enforcement on, a breached app reaches only the services that already expect it.
Every request knows who sent it.
Most apps trust a user name that any attacker can fake. Greymatter verifies the person and carries that proven identity along the request.
An agent is not exempt from the rules.
When AI acts under a person's login, its mistakes look like theirs. With Greymatter, AI agents have their own identity, separate from yours.
One identity layer for people, workloads, and AI agents.
A sign-in provider proves who a person is. SPIFFE and SPIRE prove what a workload is. Greymatter joins the two, enforces them on every connection, and carries the person to the last hop.
