The FedRAMP High Baseline Screen is not just a checklist—it is the gatekeeper for handling the most sensitive federal data. If your cloud service works with Controlled Unclassified Information (CUI), law enforcement data, or healthcare records tied to federal agencies, you need to meet the High Baseline standards. Anything less will block you from deployment.
The High Baseline defines stricter security controls than the Moderate or Low levels. Under NIST SP 800-53, it includes over 400 requirements covering access control, incident response, system integrity, data protection, and continuous monitoring. The FedRAMP High Baseline Screen is the moment you verify your environment meets these standards before authorization.
To pass, your system must implement encryption at rest and in transit with FIPS 140-2 validated modules. You need multi-factor authentication across all privileged accounts. Logging must be centralized, immutable, and retained according to federal guidance. Vulnerability scanning has to run continuously, with automation in place to remediate findings fast.
