FedRAMP-regulated cloud migration is structurally more expensive than any other compliance overlay. The premium over equivalent commercial cloud migration is typically 40 to 80 percent across one-time migration and ongoing run-rate, materially larger than the 15 to 25 percent HIPAA premium. The cost is driven by the GovCloud or Government region pricing, the multi-million-dollar 3PAO assessment cost, the multi-year authorisation timeline, and the continuous monitoring requirements. This page is the 2026 cost reference for FedRAMP cloud migration.
FedRAMP (Federal Risk and Authorization Management Program) is the US government's standardised approach to security assessment and authorisation for cloud services. Agencies that procure cloud services must use FedRAMP-authorised services for any system processing federal information. The framework has three impact levels: Low, Moderate, and High, with control counts of 125, 325, and 421 respectively. The control requirements are based on NIST SP 800-53 with FedRAMP-specific implementation guidance.
The FedRAMP marketplace at marketplace.fedramp.gov lists authorised cloud service offerings with their current authorisation status. As of May 2026 the marketplace lists approximately 350 authorised cloud service offerings, with the majority at Moderate level. The hyperscaler-foundation services (AWS GovCloud, Azure Government, Google Cloud Government) are authorised at High level and underpin the majority of agency-deployed third-party services.
The three major hyperscalers operate dedicated government regions. AWS GovCloud (US-East and US-West), Azure Government (multiple US regions including Azure Government Secret and Top Secret), and Google Cloud Government. These regions are physically separated from commercial regions and operated by US citizen personnel. The pricing premium varies by service:
Government cloud region pricing premium versus commercial (May 2026)
| Service category | AWS GovCloud premium | Azure Government premium | Google Cloud Government premium |
|---|---|---|---|
| Compute (EC2 / VMs / Compute Engine) | +15 to +25% | +10 to +20% | +15 to +25% |
| Storage (S3 / Blob / Cloud Storage) | +10 to +20% | +10 to +15% | +15 to +20% |
| Database (RDS / SQL / Cloud SQL) | +15 to +25% | +10 to +20% | +15 to +25% |
| Network (data transfer, NAT, load balancer) | +5 to +15% | +5 to +15% | +5 to +15% |
| Support plans | Same as commercial | Same as commercial | Same as commercial |
| Premium / specialised services | +20 to +50% | +15 to +40% | +20 to +50% |
The premium reflects the additional operational overhead of running dedicated government infrastructure with US-citizen-only personnel, the smaller scale economies versus commercial regions, and the additional compliance overhead in the operating model. For most FedRAMP workloads the premium is unavoidable; the workload must run in an authorised region.
A Third Party Assessment Organisation (3PAO) is an accredited firm that performs the FedRAMP security assessment. The 3PAO produces the Security Assessment Report (SAR) that the sponsor agency reviews to grant Authority to Operate. 3PAO accreditation is granted by the American Association for Laboratory Accreditation (A2LA) and the market is concentrated in roughly 50 firms.
Typical 3PAO assessment cost by FedRAMP impact level
| Impact level | Initial assessment | Annual reassessment | Continuous monitoring per year | Notes |
|---|---|---|---|---|
| FedRAMP Low | $120K to $400K | $60K to $200K | $50K to $150K | Smallest scope, fastest |
| FedRAMP Moderate | $300K to $900K | $150K to $450K | $100K to $300K | Most common impact level |
| FedRAMP High | $700K to $1,500K | $350K to $750K | $200K to $600K | Largest scope, longest |
| DoD IL4 (Moderate equivalent) | $400K to $1,000K | $200K to $500K | $120K to $350K | Department of Defense-specific |
| DoD IL5 (High equivalent) | $800K to $1,800K | $400K to $900K | $250K to $700K | DoD controlled unclassified information |
The 3PAO market is small, with limited capacity. Engaging a 3PAO often involves a 3 to 6 month wait before the assessment can start. Initial assessment work typically takes 4 to 8 months from kickoff to SAR completion. The agency review and ATO process adds another 3 to 6 months. The total path from 3PAO engagement to ATO is typically 12 to 18 months.
The FedRAMP authorisation timeline
FedRAMP authorisation requires either a JAB (Joint Authorization Board) provisional authorisation or an agency-sponsored authorisation. JAB authorisations are highly limited (FedRAMP issues approximately 12 to 20 JAB authorisations per year across all impact levels). Most cloud service offerings pursue agency-sponsored authorisations.
The sponsor agency is a specific federal agency that sponsors the cloud service offering's authorisation in exchange for the right to use it. The sponsor agency must have a genuine need for the service and must commit resources to review the SAR and grant ATO. The sponsor relationship is typically established before formal authorisation work begins, often through existing contract vehicles (GSA Schedule, SEWP, ITES-3S) that pre- qualify the cloud service provider for federal procurement.
The cost of establishing the sponsor relationship is rarely a direct cost but involves substantial business development effort: identifying agency targets, securing the sponsorship commitment, navigating the agency's specific authorisation requirements. Many cloud service offerings invest 12 to 24 months and $300K to $1.5M in business development before formal authorisation work begins.
The 325 controls in FedRAMP Moderate (and 421 in FedRAMP High) include a number of requirements that drive specific cost overhead beyond standard cloud security best practice:
A representative cost build for a FedRAMP Moderate cloud migration: cloud service offering targeting federal agency procurement, 50 servers (smaller than commercial baseline because FedRAMP workloads typically scope tightly), AWS GovCloud destination, 24-month programme from migration kickoff to ATO, sponsor agency identified.

The typical-column number, $7.9M for a 50-server FedRAMP Moderate migration over 24 months, works out at $158K per workload all-in. That is roughly 5 to 6 times the per-workload cost of equivalent commercial cloud migration. The premium decomposes into: one-time 3PAO and authorisation cost ($1.1M, $22K per workload), GovCloud pricing premium over commercial ($580K, $11.6K per workload), FedRAMP-specific labour ($1.5M, $30K per workload), and the broader compliance overhead applied across all line items.
FedRAMP authorisation is not one-time. Continuous monitoring, annual reassessments, and ATO maintenance continue indefinitely. Typical annual ongoing cost for a 50-server FedRAMP Moderate system:
Annual ongoing FedRAMP Moderate cost
| Cost line | Annual cost (typical) |
|---|---|
| GovCloud premium versus commercial (steady state) | $200,000 |
| Annual 3PAO reassessment | $200,000 |
| Continuous monitoring (ConMon) operations | $220,000 |
| Annual penetration testing | $160,000 |
| US-citizen-only personnel premium | $210,000 |
| ATO maintenance and documentation | $130,000 |
| FedRAMP-specific monitoring tooling | $100,000 |
| Annual ongoing total | $1,220,000 |
FedRAMP cloud migration is the most expensive compliance overlay in commercial cloud migration. The premium is real, the timeline is long, and the ongoing cost is permanent. Organisations pursue FedRAMP because the federal cloud services market is large ($20B+ annually) and the authorisation provides defensible market access. The cost discipline is in scoping the FedRAMP boundary tightly, choosing the lowest impact level that meets the data classification, and engaging the sponsor agency early enough to make the multi-year authorisation timeline workable.
A. FedRAMP migrations carry a much larger premium than HIPAA: typically 40 to 80 percent above equivalent commercial cloud cost across one-time migration and ongoing run-rate. The premium covers the GovCloud or Government region pricing (typically 10 to 30 percent above commercial), the 3PAO assessment ($300K to $1.5M one-time), the sponsor agency engagement model, continuous monitoring requirements, and US-citizen-only personnel requirements for FedRAMP High workloads.
A. FedRAMP Low covers non-sensitive federal data (FIPS 199 Low impact). FedRAMP Moderate covers most federal information including sensitive but unclassified data. FedRAMP High covers data where unauthorised disclosure would cause severe harm, including law enforcement, emergency services, and financial systems. The control count escalates significantly: Low has 125 controls, Moderate has 325 controls, High has 421 controls. The cost premium escalates correspondingly.
A. Not always. FedRAMP authorisation applies to specific cloud regions and services. AWS GovCloud (US) is required for ITAR and certain DoD workloads but FedRAMP Moderate workloads can often run on AWS commercial regions that have FedRAMP Moderate authorisation. Azure has similar separation with Azure Government and Azure commercial both having FedRAMP authorisations for specific scopes. The destination region decision depends on the data classification and the specific regulatory regime (FedRAMP, FISMA, ITAR, DoD CC SRG, IL5/IL6).
A. A Third Party Assessment Organisation (3PAO) is an accredited firm that performs the FedRAMP security assessment. The 3PAO produces a Security Assessment Report (SAR) that the sponsor agency reviews to grant Authority to Operate (ATO). 3PAO assessment costs typically run $300K to $1.5M depending on system scope and impact level. Annual assessments and continuous monitoring continue at $150K to $600K per year. The 3PAO market is concentrated in a small number of firms accredited by the American Association for Laboratory Accreditation (A2LA).
A. FedRAMP authorisation requires either a JAB (Joint Authorization Board) provisional authorisation or an agency-sponsored authorisation. JAB authorisations are highly limited (FedRAMP issues a small number per year). Most cloud service offerings pursue agency-sponsored authorisations, where a specific federal agency sponsors the cloud service offering's authorisation in exchange for the right to use it. The sponsor relationship is typically established before formal authorisation work begins and continues through the multi-month assessment process.
A. The total path from initial preparation to FedRAMP ATO typically takes 18 to 36 months. The path: 6 to 12 months of preparation (control implementation, documentation), 4 to 8 months of 3PAO assessment, 3 to 6 months of agency review and ATO process, with continuous monitoring after. Cloud service offerings already operating in FedRAMP-authorised regions can leverage existing authorisations at the platform level but still need to authorise their own offering. The timeline is rarely under 18 months even for experienced organisations.
