Koi (formerly Koi Security, now operating as koi.ai) is an endpoint security platform built for non-binary software — browser extensions, IDE and editor extensions, open-source packages, MCP servers, AI models, AI agents, and containers — the install surface that traditional EDR and MDM tooling was never designed to govern. The platform ships three products: Koi Endpoint (agentless discovery and governance of every binary and non-binary install across macOS, Windows, and Linux), Koi Wings (continuous risk evaluation of code, behavior, publisher ownership changes, and update channels), and Koi Gateway (a network-based gate in front of marketplaces, app stores, and registries). Koi is widely known for the security research it publishes on software supply-chain attacks including GlassWorm, Shai-Hulud, PhantomRaven, GreedyBear, and the first malicious MCP server found in the wild. Koi also operates ExtensionTotal, a free community risk-scoring service for Visual Studio Code extensions that exposes a public HTTP API and a first-party VS Code extension. Koi raised $48M and has been acquired by Palo Alto Networks.
