End-to-End solutions

SEALSQ is one of the very few semiconductor companies that can not only provide the secure chips, but also provision them from factory, over the air, or on-premises with a secure and universally trusted digital identity. This identity can be created and managed throughout the device’s lifecycle using our SaaS Certificate Management System. Very few players can offer today such a vertical value proposition covering security from root-of-trust to cloud and from birth to end for any connected device.

Throughout a quarter-century of operation, our company has filed over 130 patent applications. Our commitment to innovation, however, doesn't end there. Our dedicated research engineers are now designing and implementing post-quantum algorithms for our secure chips, to face the latest threats brought by Quantum Technology and Deep Learning together.
