Other controls in SC - System and Communications Protection

You are reading one control. How much of FedRAMP High have you already done?

FedRAMP High SC-23 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of FedRAMP High your existing evidence covers. Hold C5 (Germany) and 119 of 410 FedRAMP High controls already carry evidence.

Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 6 were rejected on the C5 (Germany) pair alone.
