Legion, a cybersecurity startup specialising in AI-driven Security Operations Centre (SOC) technology, has emerged from stealth mode with $38m in funding.
The total capital raised includes a seed round and a Series A round. The Series A was led by Coatue, with earlier participation from Accel and Picture Capital, which co-led the seed round. The company also attracted backing from several angel investors affiliated with major technology firms such as Google, Crowdstrike, and Wiz.
Founded in 2024, Legion is developing a browser-native SOC automation platform powered by artificial intelligence. Its core product is a lightweight browser extension that observes and learns from in-house security investigations, turning those workflows into scalable automation. By integrating directly into the tools teams already use, the solution eliminates the need for APIs or complex integrations.
The funding will be used to accelerate product development and scale adoption of the platform across sectors such as finance, energy, and healthcare. Legion aims to address long-standing challenges in SOC teams, which are often understaffed and overwhelmed by security alerts. Its AI system promises to reduce investigation and response times by up to 90%, and in some cases has helped enterprises eliminate the need for external SOC resources altogether.
Legion’s co-founders—Ely Abramovitch (CEO), Michael Gladishev (VP of R&D), and Eyal Fisher (CTO)—bring deep expertise from prior roles at Microsoft Sentinel and Cambridge AI research. Their platform uses computer vision and machine learning to observe analyst behaviour, learning both simple and complex investigation flows. The AI then replicates and enhances these workflows, offering either human-in-the-loop or fully autonomous threat response.
Legion CEO Ely Abramovitch said, “Most AI-driven SOCs still require complex integrations, and even then, they fail to adapt to each organization’s unique environment, making them difficult for enterprise teams to fully trust. Legion is the first browser-based platform designed to scale your team’s best instincts into AI-driven workflows. It’s fully trained within your environment, by your team, for your team. Our goal is to turn your expertise into scalable automation, letting the security team focus on what’s really important.”
Coatue managing director Sri Viswanath said, “What sets Legion apart is its browser-native AI platform. It studies how security analysts work and instantly scales those workflows, cutting investigation and response times by up to 90 percent. No rigid playbooks, no messy integrations.”
