OPTIGA™ connect IoT OC2321


Turnkey eSIM solution for cellular-connected IoT devices

Infineon´s OPTIGA™ Connect IoT OC2321 takes cellular IoT connectivity to the next level: Based on certified best-in-class Infineon security hardware, this turnkey solution allows the fast and easy deployment and management of IoT devices.

OPTIGA™ Connect IoT is based on Infineon’s best-in-class Common Criteria EAL5+ certified eSIM hardware, which is designed to exceed the security standards typically required by industry today. This adds an additional level of tamper resistance to these solutions, hardening them against physical attacks – which is especially important for devices that remain in the field for long periods of time.
