Knostic offers need-to-know based access controls for large language models, adding a customizable safety layer to tools such as Microsoft 365 Copilot and Glean. The product reshapes LLM answers to fit a user's business context and aims to prevent oversharing of sensitive information like bonuses, revenue, and M&A data. Founded by Gadi Evron and Sounil Yu in 2023, the company emphasizes knowledge-centric policies that differ from traditional allow-or-deny access controls. Knostic plans to use the new funding to bolster its offering and support enterprises in their AI transformation. The company has earned industry recognition, winning Launch Pad at both the 2024 RSA Conference and the 2024 Black Hat Startup Spotlight Competition. Its advisory board and investor interest include senior cyber leaders such as Adm. Mike Rogers (Ret.) and experienced security entrepreneurs and CISOs. Knostic builds need-to-know based access-control technology for Large Language Models to shape responses so employees receive exactly what they need per organizational policy.
