Legion, a NYC-based browser-native AI Security Operations Center (SOC) platform, emerged from stealth with $38M in Seed and Series A funding.

​The round was led by Coatue, with participation from Accel and Picture Capital (co-leads on the earlier seed round), along with angel investors from leading tech companies, including Google, Crowdstrike, and Wiz.

Founded in 2024 by security veterans Ely Abramovitch (CEO), Michael Gladishev (VP R&D), alumni of Microsoft, and Eyal Fisher (CTO), AI founder and expert, Legion introduces a browser extension AI SOC companion that turns in-house expertise into scalable automation. It trains within the organization, observing the team’s investigations, learns their patterns, and helping the system improve them. Then, it automates them at their own pace, at any scale, and without requiring any integrations or APIs.

​The platform uses vision models and a lightweight browser extension to record analyst workflows, capturing both light and complex investigation patterns and the decision-making processes of top-performing analysts. It then shows teams the workflows it learned and helps optimize them. With permission, Legion investigates and responds to threats 24/7 using existing tools, either with human-in-the-loop or completely autonomously.

It scales a team’s expertise without adding headcount. The platform doesn’t require APIs, no custom playbooks, no disruptive integrations, and it can be up in minutes. It works with any browser-accessible platform, including SIEMs, threat intel tools, email platforms, and internal, homegrown systems.

Legion is already driving security operations for Fortune 500 enterprises across finance, healthcare, and energy.
