FedRAMP High

FedRAMP High is the most stringent authorization baseline within the Federal Risk and Authorization Management Program, designed for cloud services where a security breach would cause severe or catastrophic adverse effects on agency operations, assets, or individuals. Calibrated to NIST FIPS 199 High impact levels, this baseline covers the most sensitive categories of unclassified federal data, including law enforcement records, protected health information, financial systems, and data integral to national security operations.

What is FedRAMP High?

FedRAMP High was introduced to address the needs of federal agencies whose mission systems handle data that demands the highest level of protection short of classified systems. The baseline requires approximately 421 security controls drawn from NIST SP 800-53, substantially more than the roughly 325 controls required for FedRAMP Moderate. The additional controls address areas such as advanced configuration management, stricter personnel security, enhanced physical and environmental protections, and more comprehensive incident response and recovery requirements.

Agencies with significant FedRAMP High requirements include the Department of Defense, the Department of Homeland Security, the Department of Justice, and the Department of Health and Human Services. For DoD specifically, FedRAMP High aligns with Impact Level 4 (IL4) in the DoD Cloud Computing Security Requirements Guide (CC SRG), which covers Controlled Unclassified Information. The assessment and authorization process for FedRAMP High follows the same structure as Moderate, requiring an accredited 3PAO assessment and either JAB or agency ATO review, but the scope of the assessment is considerably larger and more rigorous.

Because fewer cloud offerings hold FedRAMP High authorization compared to Moderate, the FedRAMP Marketplace for High-authorized services is more limited. This scarcity creates both a barrier to entry and a competitive opportunity for providers willing to make the investment.

Why it matters for contractors

Contractors targeting high-stakes federal programs in defense, law enforcement, healthcare, and financial regulation must ensure their cloud infrastructure holds or is actively pursuing FedRAMP High authorization. Agencies operating systems at the High impact level are not permitted to use cloud services authorized only at the Moderate level, meaning Moderate authorization is insufficient for these procurements. The cost and timeline for achieving FedRAMP High authorization are significantly greater than for Moderate, often requiring 18 to 24 months and substantial investment in engineering and compliance resources.

The limited supply of FedRAMP High-authorized offerings means that providers who obtain authorization gain access to a market segment with less competition and higher contract values. For contractors building cloud platforms aimed at DoD or law enforcement customers, pursuing FedRAMP High is often a prerequisite for meaningful market participation.

Example

A cloud infrastructure provider offers a platform optimized for database management and analytics. The provider identifies an opportunity to support an FBI program managing criminal investigative records. Because a compromise of law enforcement data would have catastrophic consequences for public safety and ongoing investigations, the FBI requires FedRAMP High authorization as a mandatory eligibility requirement in the solicitation. The provider engages a 3PAO, completes the High-baseline security assessment, and submits its authorization package to a sponsoring agency. After receiving the High ATO, the provider is listed on the FedRAMP Marketplace and qualifies for award. Other law enforcement agencies subsequently reuse the existing authorization, accelerating their own procurement timelines.
