Simbian

Simbian is an AI security operations platform built around autonomous agents that investigate security alerts and act on them. Its main product, the AI SOC Agent, investigates each alert as it is detected, gathers evidence from the customer's environment, and returns a true or false positive verdict with a severity level and a confidence rating. The platform connects to more than 100 existing tools, including SIEM, EDR, XDR, cloud and identity systems, vulnerability feeds such as NVD and CVE, threat hunting and pentest reports, and the customer's own runbooks in an ITSM or PDF. It reasons across those signals together, then takes actions in the customer's EDR, cloud and Active Directory, writes detection rules in the SIEM's own query language, and files tickets. The vendor says no playbooks are needed, that customer data stays in the customer's own tenant, and that security teams approve actions before they run, citing 95 percent approval of proposed actions. It is aimed at enterprise security teams and SOC analysts. The company also publishes research such as an AI SOC LLM leaderboard covering MITRE ATT&CK coverage across models. Pricing is not published. The site directs buyers to book a demo or talk to a security engineer.
