Outlines the regulatory remediation SLAs for FedRAMP and identifies 'Reachability Analysis' as the primary mechanism for reducing the compliance labor burden.
FedRAMP mandates strict vulnerability remediation timelines for Cloud Service Providers: 30 days for High (CVSS 7.0+), 90 days for Medium, and 180 days for Low, while prohibiting the use of container images listed in CISA's Known Exploited Vulnerability (KEV) catalog. To meet these rigorous SLAs, CSPs are encouraged to use function-level reachability analysis to mark unexploitable risks as false positives, effectively removing them from scope. Research shows that fewer than 9.5% of vulnerabilities are actually reachable at the function level, and 80% of reachable flaws have an EPSS probability under 1%, allowing CSPs to justify 'risk level adjustments' to auditors and prioritize remediation efforts on the most immediate threats.
FedRAMP requires all exploitable vulnerabilities to be remediated within strict SLA windows (30 days for High, 90 for Medium, 180 for Low), making remediation velocity the critical compliance metric.
legal and financial penalties resulting from a failure to meet federal cybersecurity compliance standards
packages with historically slow remediation cycles are the primary risk to maintaining continuous FedRAMP authorization within mandated timelines.
FedRAMP allows for risk level adjustments... based on demonstrating the actual risk is lower than the CVSS score... such as with EPSS.
Risk Guard provides CVSS scores but does not currently incorporate EPSS (Exploit Prediction Scoring System) as a standard 'Risk Adjustment' signal.
Risk Guard would be better if it integrated EPSS scores to help users justify 'Risk Level Adjustments' for compliance-heavy audits like FedRAMP.
