What it is
GovRAMP provides a common framework and a published authorization status for cloud products sold to participating governments. A provider is assessed once against the program's control baseline (Low, Moderate, or High impact) and can then present that single authorization to many state and local buyers, instead of repeating a separate security review for each contract.
Who needs it
Cloud service providers (SaaS, PaaS, IaaS) that want to sell to participating state and local agencies. A growing number of jurisdictions either require or strongly prefer a GovRAMP authorization (or an equivalent like FedRAMP) before a cloud product can touch government data.
How it compares to FedRAMP
Both are built on NIST SP 800-53 control baselines and use independent assessors. FedRAMP governs federal agency cloud use and is run by the federal government; GovRAMP serves the SLED market and is run by a non-profit. Many providers pursue FedRAMP first and use a "reciprocity" path to satisfy GovRAMP, since the underlying controls overlap heavily.
The impact levels
GovRAMP authorizations are issued at Low, Moderate, or High impact, mirroring the data sensitivity tiers used by FedRAMP. The required level is driven by the type of government data the cloud product will store or process.
