Suprbox

About

Suprbox is a policy-enforced vault system for the data your AI agents access. Instead of handling an agent your keys, you give it a scoped Suprbox key that is checked against rules you set for sensitivity, time-of-day, rate limits, and human approval, and is signed into an immutable audit log. Unlike prompt guardrails, Suprbox protects the data itself, so even a jailbroken or misconfigured agent cannot exfiltrate what your policy denies. Built for teams running real agents on sensitive documents.
