What counts as a significant change requiring FedRAMP re-assessment?

A significant change requiring FedRAMP re-assessment is any modification to a Cloud Service Offering (CSO) that materially impacts its security posture, scope, or risk profile. This includes major architectural overhauls, the introduction of new services, changes in data processing locations, or substantial modifications to security controls. Such changes necessitate notification to the FedRAMP Program Management Office (PMO) and the authorising agency, triggering a re-assessment to ensure continued compliance with FedRAMP requirements.

Practitioners must understand that "significant change" extends beyond mere technical updates. Examples include adding new cloud services or features, changing the underlying infrastructure provider, relocating data centres, or altering the organisational structure that impacts security responsibilities. Even a change in ownership of the Cloud Service Provider (CSP) can be deemed significant. The FedRAMP Continuous Monitoring (ConMon) process mandates that CSPs proactively identify and report these changes to their authorising agency and the FedRAMP PMO within thirty (30) days to determine the scope of the required re-assessment.

Failure to accurately identify or promptly report significant changes can lead to severe consequences, including the potential revocation of an Authority to Operate (ATO) or a delay in its renewal. The scope of the re-assessment, which could range from a targeted review of affected controls to a full security assessment, depends directly on the nature and magnitude of the change. Therefore, robust internal change management processes, integrated with continuous monitoring activities, are critical to maintaining FedRAMP compliance and ensuring the ongoing security of the Cloud Service Offering. Proactive engagement with the authorising agency is paramount.
