CerbIA composes security gates around AI agents' inputs and outputs. A gate loads content, optionally preprocesses it, runs scanners, aggregates blocking risk, and returns a verdict. It requires Python 3.12 or later.
Scanner results are heuristic or model-based signals, not a security certification. Evaluate them for your threat model and retain defense-in-depth controls.
- Build configurable gates from loaders, preprocessors, scanners, and score aggregators.
- Scan inline text or files through the
cerbiacommand-line interface. - Select optional local ML, Presidio PII, and ProtectAI prompt-injection integrations.
