If you’re comparing FedRAMP, GovRAMP (formerly StateRAMP), and DISA Impact Levels (DoD IL2/IL4/IL5/IL6), you’re really trying to answer two practical questions:

Who is the customer? (Federal, state/local/education, or DoD)
What kind of data will live in the cloud? (Public, CUI, mission-critical, or classified)

All three approaches exist to reduce risk and standardize how government buyers evaluate cloud security, but they’re used in different procurement ecosystems and use different “signals” to indicate trust.

At a glance

FedRAMP: Federal cloud security authorization framework (Low/Moderate/High).
GovRAMP: Public-sector cybersecurity verification for state/local/tribal/education buyers; uses program statuses (Core/Ready/Provisionally Authorized/Authorized).
DISA: DoD’s cloud model (IL2/IL4/IL5/IL6) that matches cloud environments to DoD data sensitivity; IL4/5/6 typically require a DoD Provisional Authorization.

FedRAMP: The federal “baseline” system (Low, Moderate, High)

FedRAMP (Federal Risk and Authorization Management Program) is the U.S. federal government’s standardized approach for assessing cloud service offerings (CSOs). If your buyer is a federal agency, FedRAMP language is often what you’ll see in solicitations, security reviews, and procurement gates.

A key FedRAMP concept is impact categorization: CSOs are categorized into Low, Moderate, or High impact levels (across confidentiality, integrity, and availability).

FedRAMP also has Marketplace designations that show where a cloud offering sits in the process — commonly FedRAMP Ready, In Process, or Authorized — and the Marketplace is designed to support reuse of security authorization packages across agencies.

Why it matters: If the customer is federal, FedRAMP is usually the most important “security shorthand” for whether a cloud service can be adopted quickly and reused across agencies.

GovRAMP (formerly StateRAMP): Public-sector verification for SLTT and education

GovRAMP is widely used by state, local, tribal, and education (SLTT/Ed) organizations that want a consistent way to evaluate cloud vendor security, without each agency reinventing the wheel.

You’ll still hear “StateRAMP” in the market because GovRAMP operates as StateRAMP (dba GovRAMP), reflecting its origins and evolution.

GovRAMP publishes an Authorized Product List (APL) that is updated regularly and includes offerings at different verification stages. On the APL, verified security statuses include Core, Ready, Provisionally Authorized, and Authorized (the highest level).

Why it matters: If you sell to state agencies, counties/cities, public universities, or school systems, GovRAMP is increasingly used as the “common language” to speed up vendor trust and reduce duplicative security assessments.

DISA Impact Levels (DoD IL2, IL4, IL5, IL6): How the DoD matches cloud to data sensitivity

DISA Impact Levels come from the DoD Cloud Computing Security Requirements Guide (DoD CC SRG) and are used to align cloud environments to the type and sensitivity of DoD information. The DoD CC SRG follows a FedRAMP+ concept, leveraging FedRAMP assessment work and adding DoD-specific controls and requirements.

At a high level, DoD impact levels are commonly summarized as:

IL2: Public or non-critical mission information (often tied to reciprocity when a CSO has a FedRAMP Moderate authorization).
IL4: Controlled Unclassified Information (CUI) and unclassified mission data for non–National Security Systems.
IL5: Higher-sensitivity CUI, mission-critical information, and National Security Systems (still unclassified, but stricter).
IL6: Classified SECRET and National Security Systems.

One of the biggest practical differences vs. FedRAMP: the DoD expects the right Impact Level for the specific DoD use case, and the onboarding path can include additional DoD connectivity/registration steps.

For mission owners selecting a cloud service offering, DoD guidance commonly points them to:

Review the FedRAMP Marketplace for an approved IL2 CSO, and
For IL4/IL5/IL6, ensure the CSO has an appropriate DoD Provisional Authorization (DoD PA) and is authorized/registered in the relevant DoD systems.

Why it matters: If your customer is DoD (or a DoD mission partner), the requirement is often not “Are you FedRAMP?” but “Which Impact Level can you support?”

A common point of confusion: “Is FedRAMP Moderate the same as a DoD Impact Level?”

Not exactly.

FedRAMP uses Low/Moderate/High impact levels for federal cloud offerings, while the DoD uses IL2/IL4/IL5/IL6 to match cloud environments to DoD information types and mission needs. In practice, there is a relationship — IL2 is often associated with reciprocity when a cloud service has a FedRAMP Moderate authorization — but higher impact levels (IL4/5/6) generally require additional DoD-specific requirements and authorization steps.

Which one do you need? A simple guide

You can usually choose the right path by answering two questions: Who is buying? and What data is involved?

You likely need FedRAMP if…

Your buyer is a U.S. federal agency and procurement language references FedRAMP requirements or Marketplace designations.

You likely need GovRAMP if…

Your buyers are state/local/tribal governments or education organizations that want a recognized public-sector verification status to streamline vendor review.

You likely need DISA if…

Your buyer is DoD (or a DoD mission partner) and the system must handle DoD data that requires hosting in an environment aligned to IL2, IL4, IL5, or IL6, with IL4/5/6 commonly requiring a DoD PA.
