About Simbian
Simbian sells an AI security operations platform built around autonomous agents. The company says its agents investigate alerts, run threat hunts and carry out penetration tests, then act inside the tools a customer already runs, such as SIEM, EDR, XDR and identity systems. It sells to enterprise security teams and to managed security service providers and MDR providers, and states its platform is in production across more than 300 enterprise environments. The platform reads from over 100 sources and writes back into existing controls, so customers do not replace their stack. A shared Context Lake holds assets, identities and past verdicts, and each agent learns from analyst feedback. Simbian says 95% of proposed actions are approved by the customer's own team, and that responses average under four minutes. It also offers a maturity model for grading resilience to AI attacks.
