FedRAMP's VDR and VER rules require cloud service providers to perform vulnerability scans at frequencies based on their certification class, ranging from every 14 days to daily. Remediation deadlines are tiered by vulnerability severity and exploitability, with the most critical vulnerabilities requiring fixes within 12 hours. Providers must assume exploits are automatable unless proven otherwise and must treat failures in their detection and response processes as vulnerabilities. The system producing evidence is itself in scope, requiring continuous, machine-readable validation of security controls. These requirements replace legacy monthly scans and POA&Ms with continuous validation and ongoing certification, emphasizing automation and real-time evidence over narrative documentation. The transition to FedRAMP 20x practices is underway, with full adoption expected by June 2027.

The new requirements increase the operational burden on FedRAMP-certified cloud service providers by demanding more frequent vulnerability scanning, faster remediation of critical vulnerabilities, and continuous automated evidence production. Providers must maintain robust detection pipelines and respond rapidly to findings, including during holidays. Process failures are treated as vulnerabilities, increasing accountability. The shift from periodic documentation to continuous validation changes compliance from a point-in-time activity to an ongoing engineering challenge. This may require significant investment in automation and monitoring infrastructure but aims to improve the accuracy and timeliness of security posture reporting.

The vendor advisory indicates these requirements are mandatory from December 7, 2026, with a grace period until March 7, 2027, for offerings under corrective action plans. Providers should implement automated, continuous vulnerability detection and evidence reporting systems aligned with their certification class. They must establish processes to meet tiered remediation deadlines based on vulnerability severity and exploitability, and ensure that detection pipeline failures are promptly addressed and treated as vulnerabilities. Building or acquiring modern Governance, Risk, and Compliance (GRC) capabilities that integrate real-world data and automation is essential. Since these are compliance-driven changes rather than new vulnerabilities, remediation involves operational and engineering adjustments rather than patching software flaws.
