What is Legion Security?
Legion Security offers an agentic AI security operations platform that deploys through the analyst's browser rather than through API integrations. The system observes analyst investigations, playbooks and past cases in a learning mode, then executes workflows in the browser with human oversight (companion mode) or with reduced intervention (autonomous mode). Press coverage describes it as a browser extension AI SOC companion that works across tools such as Chrome, Edge and Island. The company was founded in 2024 by former Microsoft Sentinel team members and emerged from stealth in July 2025.
