Available on Google Cloud Marketplace
Pteri-Auth is available on Google Cloud Marketplace. Explore the listing or contact KAKR Labs to discuss your authentication and authorization requirements.
The authority gap
Credentials prove access. They do not always prove authority.
PTERI adds fresh, scoped proof when a login, automated request, transfer, approval, or administrative action carries real consequences.
Unclear agent authority
An AI agent may be authenticated while its permission for this specific action remains unclear.
Excessive permissions
Long-lived access can outlast the task, resource, value, or time window it was meant to serve.
Incomplete accountability
Conventional logs can show that something happened without preserving who approved what.
One verification model
Turn intent into verifiable action.
Keep the final policy decision inside your application while PTERI helps establish the actor, the requested scope, and the resulting evidence.
