Simbian

Simbian is a Mountain View, California-based AI security company building the industry's first self-improving, autonomous security operations (SecOps) platform. Founded by serial security entrepreneurs Ambuj Kumar (formerly CEO of Fortanix) and Alankrit Chona (formerly of Twitter, Afterpay, and Spotnana), Simbian uses a patent-pending hardened LLM system called TrustedLLM™ to allow every member of a security team — from CISOs to frontline practitioners — to automate investigations, threat response, and compliance workflows across heterogeneous IT environments. The platform continuously learns from user actions to perform increasingly sophisticated security tasks autonomously, reducing manual workload while improving coverage and resolution speed.
