Executive Summary

Knostic is a Virginia startup that secures how enterprises use AI, from assistant answers to AI-written code. Its two most built-out lines are a knowledge platform that governs what assistants such as Copilot, Glean, and Gemini may answer and Kirin, an IDE guardrail that blocks unsafe AI coding-agent actions in real time. The portfolio reaches further, adding AgentMesh, an agent-supply-chain scanner announced as joining VirusTotal's program, plus OpenAnt and OpenClaw Detect. Founded by Gadi Evron and Sounil Yu, the company secured about $16 million in spring 2025. The durability question is that assistant and IDE vendors own the platforms these controls depend on and could absorb them, no cited rule mandates need-to-know AI governance, and no customer is named in the reviewed record.

Products

Product What it does
GenAI Knowledge Security Platform Detects and limits knowledge oversharing in enterprise AI assistants such as Microsoft 365 Copilot, Glean, and Gemini, so answers match each user's need-to-know boundaries.
Kirin Secures AI coding assistants such as Cursor, Claude Code, and GitHub Copilot by validating MCP servers and extensions, scanning dependencies, and blocking unsafe actions inside the IDE.
AgentMesh Threat intelligence that continuously scans AI agent skills, MCP servers, and IDE extensions for prompt injection and supply chain threats, and feeds VirusTotal's Crowdsourced AI program.
Shadow AI Spotlight Discovers unsanctioned shadow AI use across the enterprise, giving security teams visibility into which AI tools and assistants employees adopt and how they are used.
OpenAnt Open-source, LLM-powered vulnerability discovery tool that analyzes source and binaries to surface real security flaws, offered in open source and as a managed service.
OpenClaw Open-source security plugin for OpenClaw coding agents that prevents secret leaks, PII exposure, and destructive actions during agent runs.
