What are the FedRAMP compliance requirements after the 2026 rules?

The Consolidated Rules for 2026, launched June 25, 2026, become mandatory for all stakeholders on January 1, 2027. New Rev 5 applications close on June 11, 2027. Requirements now sit in four classes, A, B, C and D. Independent assessment is optional at Class A and required at Classes B, C and D. Automated validation starts at 1 method per Key Security Indicator at Class B, then 2 at Class C and 4 at Class D.

Which certification class should a cloud provider choose?

Map to the data you hold. Class A is the new pilot baseline, and it is the only class where independent assessment is optional. Class B matches Rev 5 Low and Low Impact Software as a Service, Class C matches Moderate, and Class D matches High. Choose the lowest class that covers your most sensitive workload, because each step up adds automated validation methods per Key Security Indicator. Class D is still a Phase 4 pilot with no opening date.

How fast must you report a security incident under FedRAMP?

The clock follows a PAIN rating. Without a prompt impact estimate, every reportable incident defaults to PAIN-5. That means an initial report in 1 hour, an ongoing report in 6 hours, and a final report within 6 hours. PAIN-4 and PAIN-3 use the same 1, 6 and 6 hour clock. PAIN-2 uses 24 hours, 24 hours and 1 business day. PAIN-1 uses 1 business day at every stage.

What do you have to keep submitting after you are certified?

Continuous monitoring runs on a monthly, annual, three-yearly and as-needed cadence. Each month you upload an updated Plan of Action and Milestones, an updated inventory, raw vulnerability scan files when agency agreements require them, and required reports. Inventory must change at least monthly or after any change under control CM-8, and the Plan of Action and Milestones is maintained under CA-5. Assessors run an initial and an annual assessment, plus out-of-cycle work after significant changes.

How much does FedRAMP cost in 2026?

Budget ranges, and the vendors do not agree. One 2026 estimate puts Class C at $500,000-$1,500,000 upfront and $200,000-$500,000 per year, with a 3PAO fee of $125,000-$195,000. A separate vendor estimate puts total Moderate spend at $1 million-$2 million+ and High at $2 million-$3 million+. Adding upfront to recurring gives a first-year range of about $700,000-$2,000,000 for Class C. FedRAMP publishes no official costs.

FedRAMP Compliance Requirements - What Changed in 2026

Q: Do FedRAMP compliance requirements mean I need SOC 2 or ISO 27001 first?

Sometimes, and the new rules make the entry point explicit. A Class A applicant must have completed one of three prerequisites in the past 12 months: a FedRAMP Rev 5 or FedRAMP Ready authorization, a SOC 2 Type II report, or a GovRAMP authorization. ISO 27001 is not one of the three listed prerequisites for Class A. For Classes B, C and D, the requirement is an independent assessment by a FedRAMP Recognized assessment service.

What changed in FedRAMP compliance requirements under the 2026 rules?

FedRAMP launched CR26 on June 25, 2026. The launch notice calls it one ruleset for the FedRAMP 20x program. CR26 becomes mandatory for all stakeholders on January 1, 2027. Existing Rev 5 certifications must adopt it by that date. FedRAMP says the rules should hold until December 31, 2028.

New Rev 5 applications close on June 11, 2027. After that, the parallel Rev 5 and 20x tracks end. The outcome label also changes to FedRAMP Certification, with no separate 20x or Rev 5 designation.

The four Rev 5 baselines became four certification classes:

Class A - a new pilot baseline.

Class B - the former Low and Low Impact Software as a Service baselines, now combined.

Class C - the former Moderate baseline.

Class D - the former High baseline.

Two tracks now exist side by side. The Rev 5 track closes on June 11, 2027. The 20x track runs on Key Security Indicators instead of a NIST SP 800-53 control checklist.

Date	Milestone	What it means for you
July 6, 2026	20x and Rev5 Marketplace listings open	Marketplace listings open
July 28, 2026	FedRAMP Ready becomes legacy	No new FedRAMP Ready submissions
August 3, 2026	20x Class A pipeline opens	New pilot path for eligible providers
August 10, 2026	Temporary Rev5 pipelines open for eligible Class B and C providers	Temporary Rev5 path
August 31, 2026	20x Class B and Class C pipelines open	Low and Moderate equivalents go live
January 1, 2027	CR26 becomes mandatory for all stakeholders	Existing Rev5 certifications must adopt the new rules
June 11, 2027	New Rev5 certification applications no longer accepted	Rev5 intake closes, 20x only

Oversight under 44 U.S.C. 3506 - sensitive federal information is handled.
Agency tenant need - a tenant for one agency or centralized administration.
Enterprise integration - identity, a SIEM that collects security logs, single sign-on, or a SASE that filters network traffic.
Wider use - other agencies or third parties are expected to use the service.

The memorandum also lists 6 exclusion categories, and only a federal agency can decide its own use case.

KSI means Key Security Indicator, a security outcome you must prove rather than a document you file. The table below shows what each class asks for.

Criteria	Class A	Class B	Class C	Class D
Rev 5 baseline	New pilot baseline	Low plus LI-SaaS	Moderate	High
Independent assessment	Optional	Required	Required	Required
Automated methods per KSI	0, may automate	At least 1	At least 2	At least 4
Entry prerequisite	One of three within 12 months	Independent assessment	Independent assessment	Independent assessment
Pipeline status	Open since August 3, 2026	Open since August 31, 2026	Open since August 31, 2026	No opening date

The Class C reference page lists 46 Key Security Indicators across 10 families. It does not say all 46 are mandatory at Class C. Five carry a Class C tag: CNA-EIS, MLA-ALA, SVC-PRR, SVC-RUD and SVC-VCM.

Each KSI needs a set number of automated validation methods:

Class A - may automate, with no minimum.
Class B - should automate, with at least 1 method per KSI.
Class C - must automate, with at least 2 methods per KSI.
Class D - must automate, with at least 4 methods per KSI.

Class A has one entry gate. Within the past 12 months you need one of three things. Those are a Rev 5 or FedRAMP Ready authorization, a SOC 2 Type II report, or a GovRAMP authorization. A SOC 2 Type II report tests your controls over a set period. If you have not started, read our guide to SOC 2 compliance cost for startups in 2026.

Two rules catch people out. You cannot pursue both Rev 5 and 20x certification for the same offering. Your provider must submit the application, and a third party can only prepare the documents.

How fast must you report a security incident?

CR26 runs incident reporting on a scale called PAIN. If you do not promptly estimate the impact, every incident starts at PAIN-5, the fastest clock in the system.

The deadlines come from the incident evaluation and communication reference for Class C:

PAIN rating	Initial report	Ongoing report	Final report
PAIN-5 (default)	1 hour	6 hours	6 hours
PAIN-4	1 hour	6 hours	6 hours
PAIN-3	1 hour	6 hours	6 hours
PAIN-2	24 hours	24 hours	1 business day
PAIN-1	1 business day	1 business day	1 business day

Ongoing reports continue until the incident is closed. The initial report must include coordinator contact details, a tracking identifier, the timeline, and the PAIN rationale. It must also include an estimated recovery plan. Impact also carries an N rating from N1 to N5. N1 means a minimal effect, and N5 means a debilitating effect on multiple agencies.

How much does FedRAMP compliance cost in 2026?

FedRAMP publishes no official prices, so every figure below comes from vendor estimates in Paramify's 2026 cost guide and reads as directional. The two estimates disagree, and the gap is wide. The table joins them. The first-year column adds upfront cost to the recurring annual cost from the same source. The 3PAO fee covers the outside assessor. The last column holds the timeline from the second estimate.

Class	Upfront estimate (vendor A)	Recurring per year (vendor A)	First-year total	3PAO fee (vendor A)	Typical timeline (vendor B)
Class A	$150,000-$300,000	$50,000-$100,000	$200,000-$400,000	$30,000-$45,000	Not published
Class B (Low)	$250,000-$500,000	$100,000-$200,000	$350,000-$700,000	Not published	About 12 months
Class C (Moderate)	$500,000-$1,500,000	$200,000-$500,000	$700,000-$2,000,000	$125,000-$195,000	12-18 months
Class D (High)	$1,000,000-$3,000,000+	$500,000-$1,000,000+	$1,500,000-$4,000,000+	$150,000-$250,000	18-36 months

A second estimate puts total Moderate spend at $1 million-$2 million+ and High at $2 million-$3 million+. Recurring monitoring runs $50,000-$400,000+ a year. The first estimate puts end to end effort at 6-18 months.

What must your evidence package prove?

Freshness matters more than volume, and the FedRAMP compliance requirements lean on age. The initial package must be provider-verified and validated within the previous 7 days. An independent assessment must have been finished by a FedRAMP Recognized assessment service within the previous 3 months. You can refresh an assessment by change review, unless it is more than 9 months old.

Independent assessment is optional at Class A, where a provider may submit a fresh one. It is required at Classes B, C and D. The class rules sit in the FedRAMP 20x certification rules.

What do you keep submitting after certification?

FedRAMP compliance requirements do not stop at the certification date. Continuous monitoring runs on a monthly, annual, three-yearly and as-needed cadence.

Monthly - upload an updated Plan of Action and Milestones, an updated inventory, and the required reports.
Monthly - upload raw vulnerability scan files when agency agreements need them.
Inventory - update it at least monthly or after any change, under control CM-8.
Plan of Action and Milestones - maintain it under control CA-5.
Annually - the independent assessor performs an assessment, and the agency authorizing official reviews the results.
As needed - out-of-cycle assessments follow significant changes.

What are the next steps?

CR26 replaces a control checklist with four classes, dated milestones, and a one-hour incident clock. Independent assessment is optional only at Class A, and automation rises with every class above it. Vendor estimates put the first year between $200,000-$400,000 for Class A and $1,500,000-$4,000,000+ for Class D.

Start by confirming your class and scope. Then check your date against the calendar, since Rev 5 intake closes on June 11, 2027. If you start from scratch, begin with the Class A prerequisites. For the wider picture, read our cybersecurity compliance frameworks guide.
