EXECUTIVE BRIEF
As defense contractors plan out their compliance journeys, knowing what to look for in a third-party provider is key. Working with an RPO can help streamline your compliance journey and provide more predictable outcomes during your Level 2 assessment.
Here's what defense contractors need to know about RPOs:

Cyber threats against defense contractors are intensifying fast. In 2023 alone, U.S. businesses faced over 3,200 cybersecurity incidents, costing millions and putting national defense at risk. And with the Department of Defense (DoD) tightening compliance rules under CMMC 2.0, the stakes have never been higher. Fail to comply, and you risk not just your contracts—but your company’s future.
That’s where CMMC Registered Provider Organizations (RPOs) come in.
Think of an RPO as your mission-critical partner through the CMMC jungle. They’re authorized by the Cyber AB, trained to help you interpret the evolving rulebook, and ready to shoulder the burden of compliance so you can get back to what you do best: delivering for your customers.
In this post, we’ll break down how RPOs help defense contractors like you reduce risk, move faster, and actually stay ahead of shifting CMMC requirements—without burning out your team or budget.
Let’s dig in.
An RPO is an entity accredited by the Cyber AB, formerly called the CMMC Accreditation Body, to offer consulting services to organizations working through the CMMC framework. Unlike Certified Third-Party Assessor Organizations (C3PAOs), which perform official assessments, RPOs assist Organizations Seeking Certification (OSCs) by providing pre-assessment guidance and tailored solutions to meet compliance requirements.
An RPO’s primary role is to guide contractors through the complexities of the CMMC certification process. They are staffed with CMMC Registered Practitioners (RPs), trained to understand the intricacies of the NIST SP 800-171 framework, CMMC levels, and the unique challenges of the DIB. Their role? To help you confidently meet compliance requirements and reduce risk before your official assessment.
With thousands of contractors competing for DoD contracts, achieving compliance quickly and efficiently is critical. Here’s why choosing the right RPO gives you a strategic advantage.
Making your way through the CMMC ecosystem requires interpreting technical regulations like NIST SP 800-171 and DFARS clauses. RPOs bring expertise to help your team translate these complex cybersecurity requirements into actionable steps.
Attempting to achieve and maintain compliance in-house often leads to wasted time and inefficiencies. Partnering with an RPO reduces the strain on internal resources, allowing your team to focus on core responsibilities while experts handle compliance preparation.
RPOs conduct a comprehensive gap assessment to identify areas requiring improvement. This ensures your organization is fully prepared for the formal assessment by a C3PAO, minimizing the risk of failing.
RPOs specialize in DoD cybersecurity compliance, offering targeted assistance and solutions tailored to your business. Whether you need help drafting a Plan of Action & Milestones (POA&M) or integrating secure, FedRAMP-compliant technologies, an RPO has the expertise to guide you.
Non-compliance isn’t just a technical failure—it’s a business risk. A failed assessment can disqualify you from critical DoD contracts. RPOs help mitigate this risk by proactively addressing vulnerabilities.
RPOs provide a range of specialized services designed to prepare DoD contractors for CMMC certification while addressing the unique requirements of the defense supply chain. Unlike a generalist Managed Service Provider (MSP), which may cost less than an RPO but lacks the certified experience in DoD regulations and assessments, RPOs bring expertise in compliance and security frameworks specific to CMMC.
Below is a breakdown of the core services an RPO offers.
RPOs thoroughly assess your current cybersecurity practices against the applicable CMMC standards. This evaluation identifies gaps in compliance and provides a practical roadmap to remediate these deficiencies, ensuring your organization is fully prepared for the certification process.
Developing a compliant System Security Plan (SSP) and POA&M is critical in achieving CMMC certification. RPOs create these tailored documents, ensuring they accurately reflect your cybersecurity strategy and align with certification requirements.
CMMC Level 2 is built upon the 110 security controls of NIST SP 800-171, and RPOs can offer expert guidance in implementing these practices. This ensures that your organization achieves compliance and strengthens its overall security posture.
Unlike generalist MSPs, RPOs specialize in recommending secure technologies that meet federal compliance standards, such as FedRAMP-authorized solutions. These strategic upgrades help strengthen your IT infrastructure while addressing the specific security requirements of DoD contracts.
RPOs do not stop at certification. They help establish ongoing monitoring programs to track and maintain compliance over time. By proactively identifying and resolving issues, RPOs prevent lapses that could negatively impact your organization’s ability to bid on DoD contracts in the future.
One of the key advantages of working with an RPO is their understanding of the specialized challenges faced by contractors managing Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). RPOs provide expert services beyond a generalist MSP's scope, including insider threat detection, secure supply chain processes, and customized risk management strategies.
While general MSPs may support IT operations, RPOs bring targeted expertise, certified experience, and a deep understanding of the defense sector’s unique demands. The result? Strategic support that aligns security with business success.
Organizations facing stringent regulations, like those in the defense sector, need a partner with the specific knowledge and focus to address these challenges effectively. Here’s what sets RPOs apart.
RPOs specialize in DoD cybersecurity regulations, ensuring a deep understanding of standards like NIST SP 800-171, DFARS, and CMMC 2.0. Generalist MSPs often lack this level of expertise.
RPOs are accredited by Cyber-AB and employ RPs, assuring that their guidance meets the highest standards of professionalism and compliance.
While RPOs may appear more expensive upfront, their precise understanding of compliance challenges leads to cost savings by avoiding errors and unnecessary delays.
RPOs offer solutions explicitly designed for defense contractors, ensuring seamless integration within your organization’s infrastructure.
Not all RPOs are created equal. Selecting the right partner is crucial for a smooth compliance process. Consider the following factors.
Before settling on an RPO, ask potential candidates the following questions:
