Zero Original Data Stored

Redaction is one-way. Original sensitive values are replaced in-flight and never stored on our servers.
No token maps or reverse-mapping capability exists. Even we cannot reconstruct the original data.
Audit logs store the redacted version only - what was detected, which categories, when. Not the original content.
Non-AI network logs contain metadata only - URL, domain, method, status, timing. No request or response bodies.
DPDP Act-aligned by design. Even if our database were breached, there is no sensitive prompt content to leak - originals are redacted in-flight and never stored; only the redacted version is persisted.
