Suprbox

Suprbox is a policy-gated vault for the data your AI agents read. Instead of handing an agent your Drive or S3 key, you give it a scoped Suprbox key every read is checked against rules you set (sensitivity, time-of-day, rate limits, human approval) and signed into an immutable audit log. Unlike prompt guardrails, Suprbox protects the data itself, so even a jailbroken or misconfigured agent can't exfiltrate what your policy denies. Built for teams running real agents on sensitive documents.
