About Bedrock Data

Bedrock Data (formerly Bedrock Security) builds a continuously updated metadata graph of sensitivity, lineage, and access without shipping customer data off-prem. Serverless scanners are meant to cover multi-petabyte lakes that brute-force DSPM skips for cost.

ArgusAI lets teams ask what a model or agent actually saw, then write policies in natural language against that same graph.
