WISeKey technology is in high demand in the U.S. and the Company is deploying large scale IoT applications based on standard and proven technologies (PKI, cryptographic Root of Trust, Digital certificates). The IoT will live up to its promise only if the connected devices, the data they generate, the business applications that control these devices and the services around them, can be fully trusted.  In today’s environment, where cyberattacks have become more common and increasingly sophisticated, there is an urgent need to fundamentally rethink the Security Stack for the IoT cloud.
