Let's talk about us >> Legion Security

AI has enabled cyber attackers to move faster and at greater scale than ever before. Defenders need a new kind of tool - powerful enough to keep them ahead.

This is Legion. We are building the world’s first AI security analyst, designed to see, think, and act like an expert human analyst. This is a new kind of AI-powered SOC automation - one that learns how your security team actually works and scales that capacity across the organization.

Legion is a Series A startup backed by top-tier investors, with early traction among financial services, healthcare, and manufacturing customers. The market opportunity is massive, our tech is differentiated, and we’re moving fast.

If you're excited to help some of the world’s most sophisticated security teams deploy AI that actually helps - and want to build something big from the beginning, we’d love to hear from you.
