Zymbit develops hardware and software security solutions for unattended Linux-based edge devices and Physical AI systems. The company's core offering is a "Resilience Stack" — an integrated set of tools designed to secure, update, and recover edge devices across their full lifecycle without requiring manual intervention. On the hardware side, Zymbit produces Hardware Security Modules (HSMs) and Secure Compute Nodes that provide cryptographic services, key management, physical tamper detection, power monitoring, self-destruct capabilities, and zero-trust provisioning. These modules are designed to function independently of a trusted human operator and support bare-metal recovery. On the software side, Zymbit offers "Bootware," a system that manages OS image deployment using A/B or A/S redundant partitions with automatic rollback, secure boot integration, and filesystem encryption. This enables over-the-air (OTA) updates without risk of bricking devices. The stack supports custom Linux images (e.g., Yocto, Buildroot) and is compute-platform agnostic, with stated support for Raspberry Pi, NVIDIA platforms, and custom AI hardware. Zymbit also addresses AI model security at the edge, providing mechanisms to encrypt and protect AI models during delivery, execution, and update cycles — including defenses against model poisoning and IP leakage. Target use cases include adaptive retail, drone infrastructure, autonomous vehicles, factory automation, on-premises key management, and medical diagnostic equipment. The company also offers engineering services for design, integration, and custom solutions. Its products are positioned to help organizations meet compliance standards such as NIS2 and the EU Cyber Resilience Act (CRA).
