FedRAMP Moderate vs High: how many controls do I actually have to implement?

Under Rev 5, Moderate needs 323 controls and High needs 410. That is 87 more controls, a 26.9 percent increase, spread across the same 17 control families. If you see 325 and 421 quoted, those numbers come from the Rev 4 baseline spreadsheets FedRAMP still publishes. Rev 5 removed 2 controls from Moderate and 11 from High. Low moved the other way, from 125 to 156 controls.

FedRAMP Moderate vs High: which level does a DoD IL5 workload need?

IL5 needs High, but High alone does not get you IL5. The DoD Cloud Computing SRG applies the FedRAMP Moderate baseline at all impact levels and treats High at some. An IL5 provisional authorization requires a FedRAMP High provisional authorization plus DoD FedRAMP+ controls. It also requires separation of DoD tenants from non-DoD tenants, and limits access to IL4 and IL5 data to US citizens, US nationals, or US persons.

Can a service start at Moderate and move to High later?

Yes, but it is a re-authorization rather than a toggle. The FIPS 199 high-watermark rule means that if any data in the boundary is rated High, the whole boundary is assessed at High. A move often means a new baseline, a new 3PAO assessment, evidence for the extra controls, and a new monitoring cadence for controls you already meet, such as 35-day account disable and monthly backup testing.

How much more does FedRAMP High cost than Moderate?

On 2026 published ranges, the 3PAO assessment runs $250,000 to $500,000 for High against $150,000 to $300,000 for Moderate. Readiness work runs $150,000 to $500,000 against $50,000 to $150,000. Annual continuous monitoring plus the annual assessment runs $100,000 to $300,000 against $75,000 to $200,000. Year one adds up to roughly $500,000 to $1,300,000 for High and $275,000 to $650,000 for Moderate.

What does the tailored LI-SaaS baseline mean for a small SaaS product?

The tailored LI-SaaS baseline tests 66 controls. That is far fewer than the 156 in Low and the 323 in Moderate. It is a Low Impact path for software as a service, so it does not settle the Moderate versus High question. The sources do not say which services qualify, so ask the agency and read the current FedRAMP rules before you scope the work.

Does FedRAMP 20x change the Moderate vs High decision in 2026?

The decision stays the same, but the label and the deadline change. Under 20x, Moderate becomes Class C and High becomes Class D. The Class D pilot is only planned for FY27 Q1-Q2, so today the 20x authorizations in flight sit at Moderate. New Rev 5 certifications cease on 11 June 2027. A 2026 build should target the 20x evidence and continuous monitoring model even if the authorization lands under Rev 5.

FedRAMP Moderate vs High - Which Level Do You Need?

Choosing between FedRAMP Moderate vs High depends on two things. The first is the data you hold. The second is the agency that wants to buy your service. The gap between the two levels is wider than the label suggests. Moderate needs 323 controls and High needs 410 in Rev 5, and High often costs 1.8 to 2.0 times as much in year one. Below you will find the control counts, ten tighter rules, and a price range for each level.

What actually differs between FedRAMP Moderate and High?

FedRAMP is the Federal Risk Management Authorization Program. It sets the rules for cloud services that hold federal data. A cloud provider earns an authorization from FedRAMP before a federal agency can buy the service.

FedRAMP splits those rules into impact levels. An impact level describes how sensitive the data is and what happens if it is lost. Most federal contracts cover CUI, controlled unclassified information. Moderate is the baseline for routine CUI. High is the baseline for data where a breach would cause severe or catastrophic harm.

Moderate is the reference level. Every High requirement sits on top of it. Nothing in the Moderate baseline disappears at High. The FedRAMP Moderate vs High question is about assurance depth, not about product features.

Moderate - the baseline for routine controlled unclassified information, or CUI
High - the baseline for the most sensitive CUI, with tighter rules on top
Tailored LI-SaaS - a Low Impact Software as a Service path that tests 66 controls
3PAO - a Third Party Assessment Organization that tests and certifies a provider

The Rev 5 transition overview presentation from FedRAMP lists the control counts for each level. Low needs 156 controls. Moderate needs 323. High needs 410. The tailored LI-SaaS baseline tests 66 controls. The same presentation says Rev 5 cut the total for High and Moderate. The Low baseline rose from 125 controls to 156.

Control and rule	Moderate	High
AC-1 and six others, policy review	Every 3 years and annually	Annually or after a significant change
AC-2(j) account manager review	At least annually	Monthly for privileged access, every six months otherwise
AC-2(3) disable inactive user accounts	90 days	35 days
AC-2(2) temporary and emergency accounts	Removed within 30 days	Disabled within 24 hours of last use
AC-7(b) lockout after failed logons	30 minutes	At least 3 hours
AU-11 audit record retention	At least 90 days	At least 1 year
AT-4(b) training record retention	At least 1 year	5 years
CP-9(1) backup testing	At least annually	At least monthly
CM-7(5) authorised software review	Annually or on change	Quarterly or on change
IA-4(e) identifier review	Every 90 days	Every 35 days

Each change asks for a shorter review cycle or a longer retention period.

What does FedRAMP Moderate vs High cost in 2026?

The 2026 price ranges come from one vendor guide, the Secureframe FedRAMP cost page. It lists three line items. A readiness or gap assessment comes first. A Third Party Assessment Organization, or 3PAO, charges for the assessment itself. Continuous monitoring with an annual assessment follows every year.

Add the three published ranges together and you get a first-year envelope. The inputs are readiness, the 3PAO assessment, and the first year of monitoring. Moderate lands near $275,000 to $650,000. High lands near $500,000 to $1,300,000. High therefore runs about 1.8 times to 2.0 times the Moderate figure.

Over three years, add two more years of monitoring to that first-year figure. Moderate lands near $425,000 to $1,050,000. High lands near $700,000 to $1,900,000. The widest single gap sits in readiness work. The High ceiling of $500,000 is 3.3 times the Moderate ceiling of $150,000. The 3PAO ceiling of $500,000 is 1.7 times the Moderate ceiling of $300,000.

Budget the envelope, not one number. Other 2026 vendor guides, such as the one in our FedRAMP compliance requirements guide, publish higher totals, so treat these ranges as one estimate. Compare the envelope with the FedRAMP authorization cost guide for 2026. For wider context, read the cybersecurity compliance frameworks guide.

Which level do you need?

Use the data type first. Then check the agency. Then check the overlays on top. The FedRAMP Moderate vs High choice is a scoping decision. It sets the size of your control work.

Your situation	Level to target	Extra work you still owe
Routine CUI in a civilian agency system	Moderate, Class C	The agency authorization and its own controls
DoD Impact Level 5 mission data	High, Class D	FedRAMP+ controls, tenant separation, US person access rules
Any data in the boundary rated High	High for the whole boundary	The FIPS 199 high-watermark rule blocks a split boundary
New build started in 2026	Moderate, which is Class C under 20x	New Rev 5 certifications cease on 11 June 2027

DoD means the Department of Defense. Its Impact Levels 4 and 5 sit in a separate scheme. A DoD IL5 provisional authorization needs a FedRAMP High provisional authorization. It also needs DoD FedRAMP+ controls and the Cloud Computing SRG, a Department of Defense security requirements guide.

The SRG applies the FedRAMP Moderate baseline at all impact levels and treats the High baseline at some. IL5 also asks you to separate DoD tenants from non-DoD tenants. People with access to IL4 and IL5 data must be US citizens, US nationals, or US persons.

One rule can override the rest. FIPS 199, the federal standard for classifying information, carries a high-watermark rule. If any data in the boundary is rated High for confidentiality, integrity, or availability, that data sets the level. The whole boundary is then assessed at High. You cannot split one boundary into a Moderate part and a High part.

Moving up from Moderate to High likely means a new assessment against the High baseline and evidence for the extra controls. Ask your 3PAO and the agency early.

What changes under FedRAMP 20x before the Rev 5 sunset?

FedRAMP 20x rewrites how assurance works. It moves away from testing one control at a time. It shifts toward provider-defined security goals, key security indicators, continuous evidence, and automated validation.

Under 20x, Moderate becomes certification Class C. High becomes Class D. The FedRAMP Moderate vs High split survives under 20x as two classes. The Phase 2 Moderate pilot ran from 18 November 2025 to March 2026 with 14 qualifying submissions. The first Moderate pilot authorizations were issued on 6 March 2026. Six more providers were authorized by 27 April 2026. The Class D pilot is planned for FY27 Q1-Q2, in fiscal year 2027. The only 20x authorizations in flight today sit at Moderate.

One date is firm. New FedRAMP Rev 5 certifications cease on 11 June 2027. The label you pick today can be retired within a year. Building the evidence and monitoring model that 20x expects can save rework later.

What should you do next?

Write down the data you hold and its impact level first
Ask the agency which level it expects before you scope the work
Price the year-one and three-year envelopes for your level
Build the evidence and monitoring habits FedRAMP 20x expects

FedRAMP Moderate covers routine CUI with 323 controls in Rev 5. FedRAMP High adds 87 controls and tightens 10 rules Moderate already carries. High often costs 1.8 to 2.0 times Moderate in year one. New Rev 5 certifications stop on 11 June 2027.
