CMMC Registered Provider Organization (RPO): Complete guide to becoming an RPO

A CMMC Registered Provider Organization (RPO) is an entity that The Cyber AB has authorized to deliver non-certified advisory services to help organizations prepare for the Cybersecurity Maturity Model Certification (CMMC).

An RPO is a crucial CMMC readiness provider, paving the way for a broad range of defense contractors to conduct business with government entities. Earning the CMMC RPO designation can support a variety of service lines, such as consulting, training and other CMMC advisory services.

What does a CMMC RPO do?

An RPO for CMMC provides CMMC readiness assessment and consulting services. This often involves:

• Providing gap analysis services, where they identify areas where the organization needs to improve its CMMC certification readiness
• Implementing support for companies trying to meet certification requirements
• Assisting with documentation as an organization creates a record that gives evidence of its compliance
• Preparing companies for upcoming assessments
• Training employees and leaders around the cybersecurity standards required to qualify for CMMC certification
• Providing ongoing compliance support

Obtaining your CMMC RPO designation can qualify your organization to offer these and similar services, as well as general cybersecurity consulting for organizations that may want to work with the U.S. Department of Defense (DoD).

What RPOs CANNOT do

Even though there are many tasks that fall under the CMMC 2.0 RPO role, there are some important limitations to keep in mind as you investigate how to become a CMMC RPO. Specifically, even if you have CMMC RPO designation, you can’t:

• Conduct official CMMC assessments
• Issue CMMC status or certificates to organizations
• Approve official POA&M closeout or make official assessment determinations

These distinctions are crucial when considering C3PAO vs. RPO differences. An RPO must refer clients to a Certified Third-Party Assessment Organization (C3PAO) when the company needs an official CMMC assessment.

RPO vs. C3PAO distinction

RPOs are consultants and advisors. They focus on preparing organizations for CMMC certification and remediating when they identify issues. C3PAOs, on the other hand, serve as official assessors. They validate compliance.

This distinction prevents conflicts of interest, ensuring organizations get impartial assessments. At the same time, separating the two entities' roles frees up RPOs to build deep client relationships.

CMMC RPO requirements

To join the ranks of RPO CMMC service providers, you have to meet the following requirements.

Organizational requirements:

• Register with and receive authorization from The Cyber AB
• Pass an organizational background check and provide a DUNS number
• Associate at least one Registered Practitioner (RP) with the RPO
• Sign and acknowledge the Cyber AB Code of Professional Conduct and RPO Agreement

Organizations should also maintain an appropriate business entity, good standing and any insurance required by the current RPO Agreement or needed for their services.

Personnel requirements:

• The organization needs to associate at least one Registered Practitioner (RP) with the RPO
• Certified staff must keep their certifications active

Technical capabilities

A CMMC-registered provider must have a set of technical skills to excel in their job. For instance, it’s important to:

• Demonstrate CMMC expertise
• Have an understanding of all of the NIST SP 800-171 standards
• Demonstrate knowledge of DoD requirements around cybersecurity and data protection
• Understand assessment methodologies

At the same time, RPOs, whether they operate independently or as part of a CMMC consulting organization, must adhere to a code of conduct. This requires that they:

• Maintain professional ethics
• Avoid conflicts of interest
• Maintain confidentiality
• Accurately represent their services

Step-by-step: How to become an RPO

Here’s how to become an RPO and start providing CMMC implementation support:

Step 1: Ensure you have the prerequisites

This involves forming a business entity and securing the required insurance. You must also associate at least one RP with the RPO.

It may take around one to three months to meet the requirements, especially if you’re starting from scratch.

Step 2: Prepare application materials

To prepare your CMMC RPO application, you must gather:

• Business documentation that outlines your business’s ownership and evidence of good standing
• The necessary insurance certificates
• Documents that verify the RP credentials of staff members
• Details of your company’s organizational structure
• Documentation that describes your service offerings

In total, you can expect application preparation to take between two and four weeks.

Step 3: Submit application to The Cyber AB

Submitting your application to The Cyber AB is relatively straightforward thanks to their website. You can use The Cyber AB portal to upload your documents and pay the fee.

Once you have your application materials in order, submission is fairly simple and shouldn’t take more than a week or so.

Step 4: The Cyber AB review process

Each organization’s review process is unique, but here are some things you may be asked to do:

• Verify the validity of documents
• Validate your credentials
• Provide proof of insurance coverage
• Satisfy requests for additional information

The time the review process takes depends on what you need to provide, but a period of four to eight weeks is typical.

Step 5: Approval and listing

Once you’re approved, you receive your official RPO designation. You also get listed in the RPO marketplace, so those looking for CMMC consulting can find you more easily.

In addition, you also earn the right to advertise using the RPO logo, which identifies you as an approved service provider.

Generally speaking, this should all happen within about a week after you get approved.

The Cyber AB currently lists RPO registration duration as approximately three weeks, including the background check. Companies starting from scratch may need additional time to form the business, associate an RP and prepare service operations.

Costs and fees

Starting an RPO requires an upfront investment. At the same time, you can experience significant ROI once you’ve been approved.

Initial costs

Your initial costs consist of:

• An application fee of approximately $6,000
• Obtaining professional liability insurance: Between $2,000–$10,000 per year
• Earning RP designation(s): Cyber AB currently lists $600 for RP application, training and testing, plus a $125 international background check if applicable. Optional prep or additional training would be separate.
• Forming a business entity if you don’t already have one: Between around $500 and $5,000

Annual fees

To maintain your RPO status, you must pay for:

• An annual RPO renewal fee of $5,000
• Insurance renewal: $2,000–$10,000
• Staff certification maintenance, which varies depending on the number of people certified
• Marketing and business development, which varies depending on the extent of marketing and development you undertake and the tools you use

Therefore, a reasonable figure for your total initial investment may be between $10,000 and $30,000, depending on business setup, insurance, staffing, marketing and optional training costs. The Cyber AB RPO application fee itself is currently listed at $6,000, with a $5,000 annual renewal fee.

Note that fees are subject to change per The Cyber AB. It’s also important to factor in your annual operating costs, which may be between $5,000 and $20,000 before factoring in revenue.

RPO business model

One of the benefits of being a CMMC RPO is the revenue it can generate, but earning consistent revenue requires establishing a business model. Your model should be built on:

Revenue opportunities

There are several ways to earn money as an RPO, but some of the more common avenues and market-estimate ranges include:

• Offering gap assessment services: $5,000–$50,000 per engagement
• Providing implementation support: $10,000–$200,000+ per client
• Providing ongoing compliance consulting: $2,000–$10,000/month retainers
• Training an organization’s staff: $1,000–$5,000 per session
• Providing documentation services: $5,000–$30,000

Typical client engagement

The services you provide to clients will vary depending on their current cybersecurity posture and CMMC gaps. But here’s a list of what a typical client engagement may look like, particularly if a client is starting their CMMC readiness from scratch:

1. Initial gap assessment to identify where they need to make improvements.
2. Remediation planning to set up a step-by-step strategy for addressing each gap.
3. Implementation support, where you guide them through implementing controls and tools to close gaps.
4. Pre-assessment readiness, where you prepare a report that outlines what they need to do before their official assessment.
5. C3PAO coordination, which involves helping them choose a C3PAO and scheduling their assessment.
6. Post-assessment support, which focuses on addressing any issues the assessment revealed and/or making sure they remain compliant going forward.

Target market

Your target market varies according to RPO services by CMMC level, but includes any organization that currently contracts with the defense industry or may do so in the future, such as:

• Defense contractors of all sizes
• Defense industrial base (DIB) supply chain companies
• Organizations new to CMMC
• Companies needing Level 2 compliance

Marketing your RPO

Marketing your RPO is slightly different than marketing a regular service provision company because your target market is a little more focused. Also, there are already some marketing channels in place that you can take advantage of. A typical marketing plan may consist of:

• A Cyber AB marketplace listing
• Attending industry conferences and events
• Performing direct outreach to defense contractors
• Forming partnerships with C3PAOs
• Content marketing and thought leadership
• Taking advantage of referral networks

Building your RPO team

Assembling a talented team enables you to deliver effective services while maintaining a lean organization.

Essential roles

The backbone of your RPO team consists of:

• At least one, but preferably two or more RPs
• Technical security specialists
• Documentation experts
• Project managers
• Business development staff

Hiring considerations

Keep these points in mind as you recruit talent:

• NIST 800-171 expertise is critical
• Defense industry experience adds even more value
• C3PAO experience is especially valuable

Training and development

Your team has to stay current on the latest CMMC developments and assessment methods. Therefore, you need systems in place to:

• Keep team certifications current
• Administer continuous learning on CMMC updates
• Implement NIST framework training
• Continually update your team on the most effective assessment methodologies

RPO service offerings

The services you offer are tailored to clients' needs and where they are in their CMMC assessment journey. The ranges below are market estimates and vary by scope, client complexity and provider experience.

Gap assessment services

During gap assessments, you:

• Conduct initial readiness evaluations
• Perform NIST 800-171 compliance checks
• Define the scope of your assessment readiness services
• Build detailed findings reports

• Providing configuration guidance

Expect to spend between three and 12 months on CMMC implementation services, and you can charge between $25,000 and $200,000.

Pre-assessment preparation

Pre-assessment prep is a detail-oriented process where you use assessment frameworks to guide your efforts. During assessment preparation, you may have to:

• Collect evidence
• Review documentation
• Perform mock assessments
• Verify when the organization is ready for a real assessment by a C3PAO

The typical engagement period for pre-assessment preparation should be between one and two months, and you should be able to charge between $10,000 and $50,000, depending on what needs to be done to get them ready for the actual assessment.

Ongoing compliance support

Once your client has had their assessment, you can also provide services that help them maintain their CMMC status by:

• Assisting with continuous monitoring
• Performing annual reviews
• Updating their controls and tools, when necessary
• Preparing them for recertification

Typically, ongoing compliance support involves a monthly retainer, and you can charge between $2,000 and $10,000 per month.

Training services

Training is key because it can ensure an organization has the internal knowledge needed to make recertification easier and preparation faster. With this in mind, your training services may include:

• Offering CMMC overviews
• Teaching about NIST 800-171 standards
• Role-specific training
• Security awareness training, both in general and by department

A training session should last between one and five days, and you can invoice the company for between $1,000 and $5,000 per day, depending on the kind of training and the number of learners.

RPO and C3PAO relationships

Strong partnerships enhance success because they build synergistic, mutually beneficial relationships. For instance, an RPO can help clients prepare for CMMC assessment, and a C3PAO they partner with can perform the actual assessment. However, RPOs should not imply guaranteed assessment outcomes and should avoid conflicts of interest with assessment organizations.

By building a natural referral relationship and taking advantage of professional networks, you can generate ongoing business. You can also attain better client outcomes because you know what your C3PAO partner expects to see in their assessments and can prepare clients accordingly.

Best practices

To create a consistent revenue stream using partnerships, you should:

• Establish C3PAO relationships early
• Clearly communicate with clients
• Never guarantee assessment outcomes
• Avoid conflicts of interest
• Maintain your independence as an RPO, regardless of the nature of each partnership

Referral protocols

You should hand a client off to a C3PAO once you’re certain they are ready for a formal assessment. It’s best to establish these prior to engaging with the client.

You then introduce the client to the C3PAO and provide details about the assessment level they’re aiming for and the nature of their business. After the assessment, you should follow up to see how it went and any takeaways you can use to continue supporting the client.

Common RPO challenges and solutions

Here’s a list of common challenges that you can overcome using a proactive approach:

• Finding clients: Maintain an active marketplace presence, networking and content marketing.

• Configuration management databases
• Evidence collection systems

Legal and insurance considerations

Protecting your business from legal and liability risks involves segmenting your risk mitigation strategy into:

Professional liability insurance

• Errors and omissions coverage is essential.
• Cyber liability is recommended.
• You have to establish minimum coverage amounts.

Keep in mind this will involve annual premium costs, which can impact the kinds of liability coverage you sign up for.

Contracts and agreements

The following contracts and agreements can limit your legal risk:

• Service agreements
• Non-disclosure agreements
• Limitation of liability clauses

It’s also crucial to clearly define the scope of each engagement. This prevents scope creep and ensures clients know what to expect ahead of time.

Compliance and ethics

Following compliance guidelines helps keep you in business and delivers transparent, dependable service to your clients. Some top considerations include:

• Maintaining the RPO code of conduct
• Having strict conflict-of-interest policies
• Maintaining confidentiality
• Retaining records

Maintaining your RPO status

Qualifying to continue to do business as an RPO is fairly straightforward if you keep the following top of mind:

Annual requirements

Your annual obligations include:

• Paying an annual maintenance fee
• Maintaining insurance required by the current RPO Agreement, client contracts or your own risk-management plan
• Keeping your staff’s certifications active
• Updating your marketplace profile
• Adhering to and attesting to the RPO code of conduct

The Cyber AB audits

Audits by The Cyber AB are part and parcel of the business. They may be random and involve:

• Documentation review
• Credential verification
• Review of client feedback

Consequences of non-compliance

If you fail to meet compliance standards, you will likely receive a warning and be granted a remediation period to address the issues impacting your compliance. If you fail to meet the remediation requirements, your RPO designation will be suspended, and you will be removed from the RPO marketplace. It’s also possible to have your designation completely revoked.

Market outlook for RPOs

The future looks good for RPOs because ongoing cyber threats will continue to underscore the need for CMMC compliance. More than 300,000 organizations need to align with CMMC standards, creating significant demand for readiness and implementation support.

C3PAOs conduct official assessments rather than guiding implementation, so RPO demand is tied to the preparation, remediation and ongoing support organizations need before assessment.

As requirements become more complex, the demand for professional services will continue to rise, along with the need for ongoing consulting and guidance.

The RPO competitive landscape and growth opportunities

With more and more RPOs entering the market, it’s crucial to differentiate your offering. By specializing in certain industry sectors and customizing your services to niche needs, you can stand out from the crowd.

The surging need for Level 2 implementations is likely to drive growth for smaller RPOs. By providing ongoing support, training and awareness services, you can meet companies where they are and help them close their CMMC gaps.

It’s also important to integrate technology into your systems to make your business more efficient and scalable. With a flexible technology infrastructure, you can take on more clients while minimizing your overhead spending.
