The SARA-R5 series is a 5G-ready, software-configurable family of IoT devices that support LTE-M and NB-IoT communications over multiple radio bands. It includes a secure element, certified to the Common Criteria EAL5+ High security assurance standard, which also acts as a hardware root of trust (RoT) for processes such as authentication and encryption.

The GSMA launched the IoT SAFE recommendation in December 2019. It enables IoT device manufacturers and service providers to use a SIM as a robust and scalable hardware RoT to protect IoT data communications. This will make it easier to securely establish a (D)TLS session with an application cloud/server, simplifying the process of provisioning and managing millions of IoT devices.
