Knostic

Knostic is a cybersecurity company focused on AI security for enterprise environments, specifically on controlling what information large language models (LLMs) can surface to users within organizations. Detailed public information about the company — including founding year, funding, headcount, and exact headquarters — is limited.

Knostic's product addresses a specific problem that has emerged with enterprise adoption of generative AI tools: employees using organization-connected LLMs (such as Microsoft Copilot) can inadvertently access sensitive information they are not authorized to see, or extract data that should not leave the organization. Knostic provides a need-to-know access control layer that governs what each user is permitted to receive as an answer from enterprise AI systems — not merely what files they can open, but what the AI is allowed to reveal in response to their queries.
