TrustKernel

PlugOS is an Android-based secure and private operating system that runs entirely inside PlugMate — a USB-powered, thumb-sized device with its own processor, memory, and fully encrypted storage.With true plug-and-play simplicity, PlugMate instantly provides a physically isolated, hardware-enforced private workspace on any iPhone, Android device, Mac, or Windows PC — a trusted environment designed for confidential work, private communication, and digital-asset security.
All sensitive tasks, identities, keys, and communications stay inside PlugOS under hardware-level isolation, encryption, and zero-trust protection, completely separated from the host device.
Private activity stays in PlugOS; your phone or laptop stays your everyday device — with no tracking, no exposure, and no data leaks.
