## Executive Summary

Legion Security sells a security operations tool that installs as a browser extension, watches analysts work inside whatever tools they open, and learns to replay it with no integrations. The payoff is fast deployment and reach into homegrown systems no API exposes. Two founders held senior roles on the Microsoft Sentinel team Legion now sells against, and Coatue led a $30 million Series A after an $8 million seed from Accel and Picture Capital, with angels who work at Google, CrowdStrike, and Wiz. The proof comes from Legion and the press: its Fortune 500 adoption across finance, healthcare, and energy is vendor-reported, and public sources document no independent benchmark of the extension in a SOC it has not learned.
