AI is drastically scaling the number and novelty of threats, and security teams need to keep up.
Security teams are overwhelmed by repetitive workflows, distracting them from the more complex high-value threats.
Enterprises need accountability and predictability, but upkeeping playbooks is expensive and tribal knowledge is often siloed.
Teams hesitate to adopt externally trained models which can't follow the complexities inherent in a modern enterprise.
The only AI that learns to walk before it runs — and only runs when you say so. Legion lives in the browser, exactly where your analysts work, and builds its understanding from your team's recorded investigation sessions, the decisions they make, the paths they take, and the patterns that emerge across real cases in your environment.
Legion’s browser extension observes and learns from analyst activity in real time, capturing and structuring your organization’s tribal knowledge into dynamic playbooks.

Legion executes complete workflows directly through analysts’ browsers, maintaining full human oversight and control at every step.

When the time comes, Legion assumes its own operational workload—proactively automating investigations and engaging your team only when human input adds value.
