Overview

BigID discovers where sensitive data actually lives, classifies it, and then governs it. The hard part of data security has never been writing the policy, it is knowing what you hold and where, which is the question most organisations cannot answer about their own systems.

It covers cloud and on-premise stores alongside AI systems, which matters now that copies of company data end up inside model context and vector stores that sit outside the databases security teams already watch. AskBigID lets a team query their risk posture in plain language rather than through a console.

It is enterprise software sold to large organisations, with Fortune 500 customers and no published pricing. The breadth that makes it useful also makes it a real deployment rather than something a small team turns on in an afternoon.
