SIM & eSIM Security
Service Overview
SIM and eSIM security depends on layers that rarely get scrutinized together: the physical card, the OTA provisioning channel, and the subscription management platform behind it. Rutters Solutions assesses all three, stress-testing cryptographic keys, Java Card applets, and SM-DP+/SM-SR servers against cloning, tampering, and unauthorized profile switching.
A named senior consultant owns each engagement from scoping through remediation review, so you always have a single, accountable point of contact with real hands-on telecom security experience.
