What is Knostic?
Knostic is the world's first provider of need-to-know based access controls for LLM-based Enterprise AI, founded in 2023 by cybersecurity experts Gadi Evron and Sounil Yu. The platform enables organizations to accelerate LLM adoption and drive AI-powered innovation without compromising security or safety. It provides comprehensive visibility for Microsoft 365 Copilot, Glean, and other LLM-based Enterprise AI tools, helping enterprises identify potential oversharing, undersharing, and inference risks.
The platform's core capabilities include a Copilot Readiness Assessment (CRA) for discovery and remediation, a simulation engine that runs persona-based prompt patterns yielding a readiness score (0–100) with prioritized remediation, and need-to-know IAM for LLMs. It features a real-time AI firewall and DLP gateway (Prompt Gateway) that inspects prompts/responses, continuous surveillance for policy drift with audit trails and dashboards, and adversarial testing/red-team tooling including a free RAG Security Training Simulator. Knostic also discovers and secures AI agents and coding assistants, including supply chain risks like MCP servers, skills, IDE extensions, and rules, while detecting shadow AI and blocking data exfiltration.
Knostic is designed for enterprises adopting AI tools such as Microsoft 365 Copilot and Glean, particularly large organizations managing sensitive data. It targets CISOs and security professionals in Fortune 500 companies who need to prevent AI/LLM oversharing and knowledge-layer leaks. The platform helps organizations analyze existing permissions, derive appropriate need-to-know levels, and provide targeted guidance to remediate over-permissioned users and improperly secured content.
