Amazon Web Services has introduced new preventive controls designed to automatically enforce compliance with the enhanced FedRAMP 20x certification requirements for US government agencies. The controls shift the security model from detective to preventive, blocking non-compliant configurations before deployment rather than flagging them afterwards. FedRAMP 20x represents a stricter baseline than the current FedRAMP High standard, requiring additional security measures for sensitive government workloads. The move could set a benchmark for other cloud providers serving public sector clients, particularly as governments worldwide tighten cloud security requirements.
