About Legion Security
Legion Security sells Legion, which turns a team's knowledge, tools and processes into agents that investigate alerts, carry out approved responses and continuously learn. Legion maps a team's knowledge, people and processes and grows with every investigation. Legion Security is building an AI security analyst designed to see, think and act like an expert human analyst. Legion Security built a companion that captures how a team actually works, and scales it.[2][3][4][5][6]
Legion learns a team's current processes, tools and context from the browser, past cases and more, and deploys agents for the team. Legion continuously learns from browser recordings, cases, tools and more. Legion starts from a browser recording, runbook or past case and turns it into an agent that the team reviews, refines and deploys. Agents in Legion reason where judgment matters and follow fixed steps where consistency does, in a single workflow. Legion lets teams build agents for the processes they run, in the tools they already use.[3][4]
Legion integrates with all of a team's tools, with or without APIs. Legion comes with prebuilt integrations for all common security tools. Legion integrates with anything accessed through the browser.[3][7]
Legion investigates everything, clearing false positives and benign activity, and escalates what matters and contains threats. Legion triages and investigates alerts with an organization's context and tunes detections from what it finds. Legion works across the teams that security depends on, including the SOC, identity and DLP. Legion is running in production across the SOC, DLP, identity, vulnerability management and GRC. Legion supports separating real exfiltration from false positives, establishing who did what and why, then revoking access, quarantining data or closing the exposure. Legion supports testing exploitability against an environment to prioritize real risk, then driving the fix with the teams that own it. Legion supports checking whether a threat is active against an organization's assets and feeding what is learned. Legion helps find which alerts, workflows and tasks take the most time and which are ready to become agents. Legion lets users ask one question across all their tools, hunt new threats and hand strong leads to the Investigator. Legion lets users describe a report or board summary, schedule it and ask what is behind the numbers.[3][4]
Legion runs agents beside analysts on live cases so the two can be compared decision for decision. Before agents gain authority, each is tested against the customer's benchmarks. Legion begins by observing, then supporting, and only takes on autonomous workflows when the customer's team decides it is ready. Every insight Legion captures, every suggestion it offers and every action it takes is visible, explainable and reversible.[3][4][8]
Legion operates through a browser extension, with the customer having full control over what data is collected and when. Legion operates directly in the browser without integrations or APIs. Customers decide when Legion records by starting and stopping it manually, set a browser-level allow list for where recording happens, and use masking rules that redact sensitive data. Legion does not train models on business data by default. Legion has a built-in DLP layer to help prevent unintended data exposure. Legion aligns with frameworks including SOC 2, ISO 27001 and HIPAA where applicable.[8]
CrowdStrike users can access Legion on the CrowdStrike Marketplace, with deeper access to Charlotte AI and CrowdStrike tools. Legion can be purchased on the AWS Marketplace. Legion is offered through GCP Marketplace and works natively across Google products from Chrome to GTI. Legion Security describes itself as a Series A startup with early traction among financial services, healthcare and manufacturing customers.[3][4][5][7]
