Protects sensitive conversations

Knostic enforces need-to-know boundaries before AI tools respond, preventing unintentional exposure of HR files, legal docs, or internal case details, without relying on manual reviews

Don’t promise

Prove that only the right people can see sensitive HR or legal knowledge.
