Knostic is an AI security company that gives enterprises visibility and control over how copilots, large language models, and AI agents access and share internal knowledge. Its platform detects knowledge oversharing, enforces need-to-know access policies, and finds unsanctioned AI tools across coding assistants, MCP servers, and enterprise LLMs such as Microsoft 365 Copilot and Glean. Knostic was founded by Gadi Evron and Sounil Yu, creator of the Cyber Defense Matrix, and has raised roughly $11 million. It serves security, governance, and engineering teams in regulated sectors including finance, healthcare, and government.
