FedRAMP 20x is transforming both the structure of the FedRAMP program and federal compliance as a whole. Organizations that have Rev 5 Authorization now find themselves asking how the transition process works and the steps they need to take in preparation. Read on to learn the differences between Rev 5 and 20x, a timeline for transitioning, and best practices as your organization navigates its future in federal compliance. 

FedRAMP Rev 5’s history 

Rev 5 is the legacy path to FedRAMP Certification that introduced a threat-based methodology to determine which controls to add on to the established NIST 800-53 Rev 5 baselines. 

This process is being completely replaced by the new FedRAMP 20x Certification process according to the Consolidated Rules of 2026. Rev 5 is now considered a legacy certification process. 

If your organization is currently FedRAMP Rev 5 certified, you will need to transition to the new 20x rules eventually. Evaluate the changes you’ll need to make to your program and take action now so you’re ready for your next assessment.  

What’s changed? 

FedRAMP 20x is the program’s modern, faster path to a FedRAMP Certification. Previously, Rev 5 required an agency sponsor and evidence was submitted as point-in-time manual documentation. FedRAMP 20x ushers in a modern process that is designed to make it easier to become compliant and will open up more opportunities for CSPs to work with the federal government.  

Key changes to the program include:  

• Automation of compliance: Using machine-readable processes to reduce manual tasks.  

• Adoption of industry standards: Aligning with frameworks like SOC 2 to leverage existing security investments.  

• Continuous monitoring: Validating security through real-time data instead of point-in time- evidence, with an independent assessment still required annually.  

• Direct collaboration: Encouraging more agile relationships between CSPs and federal agencies.  

• Rapid innovation: Eliminating delays to enable faster adoption of secure cloud services.  

FedRAMP 20x classes 

FedRAMP 20x introduced a new set of certification classes that apply across the program. Each class reflects the level of risk a cloud service offering is considered adequate for. These classes include: 

Class	Presumption of adequacy
Class A	Class A Certifications are for cloud services with mature security and compliance programs that are looking to enter the federal marketplace. Class A requires a small amount of information in advance and a small subset of initial ongoing monitoring and reporting requirements.
Class B	Class B Certifications are for cloud services that provide fairly common small-scale or light use services where an entire agency is unlikely to use the service for important work so considerable additional investment in ongoing maintenance and reporting activities is not expected.
Class C	Class C Certifications are for cloud services that provide common enterprise services that are likely to be used in systems across an entire agency or that provide important government services.
Class D	Class D Certifications will be developed during FedRAMP 20x Phase 4.

Note that Class D is not yet available under 20x. FedRAMP expects to pilot it in 2027 

Timeline 

Your organization should determine when it makes sense to transition to the new 20x process. Consider how your renewal dates line up against the program’s end dates: do they overlap? Will you end up needing to renew after the deadline for applications has ended? FedRAMP has not set a final end date for existing Rev 5 certifications but expects it to be no later than 2029.  

Decide this piece on a mapped timeline, not under a deadline. 

July 4, 2026: The Consolidated Rules for 2026 took effect. From this date, all new FedRAMP  20x certification applications must follow CR26. 
January 1, 2027: For FedRAMP Rev 5, all new applications for FedRAMP Certification must comply with CR26, and certified offerings must follow the new rules. 
March 7, 2027: The grace period for the new vulnerability detection and reporting rules ends. Offerings that do not comply will have their FedRAMP Certification revoked. 
June 11, 2027: FedRAMP will stop accepting applications for new Rev 5 Certifications. 
February 1, 2028: All grace periods for CR26 expire and all cloud service offerings that are not fully following CR26 will lose their FedRAMP Certification. 

How should your organization prepare? 

If your company is currently Rev 5 certified, you’ll need to consider changes defined by the Consolidated Rules of 2026 as you prepare to transition to 20x, regardless of your planned timeline. Lay the foundation for your next assessment by evaluating and updating your approach to the following updates. 

Transition to machine-readable evidence 

One of the major changes to the FedRAMP process is machine-readable evidence. This update will expedite the process but requires preparation. Rather than preparing evidence with PDFs and spreadsheets, your team will need a system that can generate evidence using FedRAMP’s published JSON schemas. OSCAL remains an approved but optional format. Audit management platforms can simplify this process by ingesting your evidence, validating the controls, and producing the assessment package directly. 

Evaluate your current frameworks 

Does your organization have a SOC 2 Type II report completed within the last 12 months? You may be closer to starting your path to FedRAMP 20x than you think. Consider other frameworks that your organization holds and how they can be mapped to the new 20x standards.  

Audit consolidation can be a game changer for your compliance strategy too. SOC 2, ISO, and penetration testing can be run under the same roof as your federal work, streamlining your compliance program as specialized teams coordinate rather than starting from zero. 

Consider your profile 

Which class and path will your organization pursue when it’s time? This will determine what your assessment process looks like. This is made up of decisions your organization will make about the standards you’ll comply with, which audience you’re selling to, and what aligns most with your offering. 

Consider the following: 

• Will you pursue Rev 5 or FedRAMP 20x? This will define your type. 

• Which certification path applies to you? FedRAMP 20x uses Program Certification only. Agency sponsorship exists only under Rev 5. 

• Which certification class aligns with your offering and your customers’ security requirements? 

Asking these questions now will help your team prepare appropriately for your next assessment, whether it’s Rev 5 or 20x. 

Choosing the right independent assessor 

Working with the right independent assessor is key to your success during this transition period. You’ll be working with this assessor throughout the process and spending a lot of time together, so consider the following: 

• Expertise: Assessors must be accredited by the American Association for Laboratory Accreditation (A2LA) Cybersecurity Inspection Body Program to qualify for FedRAMP Recognition. This accreditation assures that assessors are in good standing themselves with the tools and experience to assess your organization.  

• Experience: In addition to technical qualifications, an assessor with deep federal experience is key to a high-quality assessment. You should also ask how many years of experience auditors on the team have. These qualities demonstrate a deep understanding of federal compliance and how to guide customers through the process, ensuring that your assessment experience is high quality. 

• Quality: Beyond accreditation, choosing a quality assessor is crucial. Choose an assessor that has a wide range of experience in federal compliance and with cloud service providers. You’ll also want to ask any potential assessor about their reports. Any quality assessor should provide thorough, actionable insights when sharing a final report. 

• Technology: Working with a tech-enabled assessor used to be nice to have, now it’s a necessity. Whether through partnerships or an in-house audit platform, technology empowers your assessors to work smarter, saving you time in the process.
