Principal Software Engineer
Exein exists to solve this. We build the security layer for a world where physical and digital threats are no longer separate problems, from kernel‐level runtime protection on embedded devices to cloud‐native platforms that analyze, protect, and prove compliance across entire device fleets. We're not patching the old model. We're building security from the core out.
