What is FedRAMP
The Federal Risk and Authorization Management Program (FedRAMP) is a government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services. This is a process by which government agencies can determine if services provided by a Cloud Services Provider (CSP) are secure enough to be used by the federal government. FedRAMP is mandatory for federal agency cloud deployments.
The Federal Government provides in-depth materials to companies and a process by which they may get FedRAMP authorized. The FedRAMP site is a good resource for companies looking to get certified.
