Cybersecurity Startup Legion Raises $38M Funding, Emerges From Stealth

Legion, a cybersecurity startup founded in 2024 by security veterans from Microsoft Sentinel and Cambridge AI research, has emerged from stealth mode after raising $38 million in seed and Series A funding led by Coatue, with participation from Accel, Picture Capital, and angel investors from major tech firms like Google and Crowdstrike. The company offers a browser-native AI Security Operations Center (SOC) platform that uses a lightweight browser extension to observe, learn, and automate cybersecurity investigation workflows, aiming to reduce burnout by triaging alerts faster and filtering false positives. Unlike traditional SOC solutions that require complex integrations, Legion's AI is fully trained within an organization's environment and can autonomously investigate and respond to threats across any browser-accessible platforms. The platform is already adopted by Fortune 500 companies in energy, finance, and healthcare, with reports of up to a 90% reduction in investigation and response times. Picture Capital, a newly public venture firm led by cybersecurity industry veterans, counts Legion among its first investments, highlighting strong confidence in the startup's innovative approach to cybersecurity. Legion CEO Ely Abramovitch emphasizes that the goal is to scale in-house expertise into AI-driven workflows, allowing security teams to focus on more critical tasks amid a growing landscape of sophisticated cyber threats.
