Finding the right CMMC RPO in Virginia takes some work. Not every firm listed on the Cyber AB marketplace is the same, and for small defense contractors, picking the wrong one is an expensive mistake.
CMMC requirements are now being incorporated into applicable DoD contracts as part of the ongoing phased rollout, with broader implementation continuing over the next several years.
CMMC represents a significant investment for small defense contractors. Many organizations should budget tens of thousands of dollars for readiness and assessment, though actual costs vary widely depending on scope, existing cybersecurity maturity, infrastructure needs, and compliance gaps. The timeline is just as demanding. Getting audit-ready typically takes 9–12 months.
A good CMMC Registered Practitioner Organization (RPO) will help you make the most of that investment, guiding you through the process so you can avoid costly mistakes, wasted time, or failed assessments. They should assist with scoping, gap analysis, remediation planning, and documentation preparation—including SSP-System Security Plan, POA&M-Plan of Action & Milestone, policies, and evidence collection—while your organization remains ultimately responsible for implementation and compliance.
While our CMMC consulting services and CMMC managed IT services are a great fit for smaller defense contractors, we realize we’re not a perfect match for everyone. With that in mind, I’ve put together this list of some of the best CMMC Registered Practitioner Organizations in Virginia.
RPO status should always be verified directly through the Cyber AB marketplace before engaging any provider.
QUICK ANSWER:
Who are the best CMMC RPOs in Virginia?
E-N Computers is a Registered Practitioner Organization with decades of experience meeting the IT needs of Virginia businesses. Other Virginia CMMC RPOs that we’re happy to recommend include NeoSystems, GRS Technology Solutions, First Column IT, C3 Integrated Solutions, and GuidePoint Security.
How to choose a good RPO
- Verify their credentials first: Pull up the Cyber AB Marketplace and confirm the firm is listed as an RPO before you go any further. Check whether they’re also a C3PAO while you’re there — it’s useful for planning. Just keep in mind that the firm preparing you can’t be the one assessing you.
- Scope before solutions: Good RPOs don’t open with a product pitch. They start by figuring out where your CUI lives, how it moves through your business, and whether an enclave approach makes sense. Any firm that skips this step and jumps straight to controls or tools hasn’t done the work.
- Get it in writing: Verbal guidance isn’t a deliverable. Expect your RPO to produce an SSP, POA&M, policies, asset inventories, and evidence plan. Firms that do this consistently tend to say so plainly on their website.
- Sector experience matters: A contractor in aerospace has different quirks than one in construction or manufacturing. Look for an RPO that’s already worked in your space — they’ll get up to speed faster and spot the issues others miss.
- Ask how the engagement actually runs: What do you own versus what do they handle? How often do you check in? What does your team’s time commitment look like? A credible RPO has clear answers. Vague timelines or “we handle everything” claims are worth questioning.
- Progress should be measurable: Gap analysis should tie to NIST 800-171 scores, and remediation steps should map directly to CMMC practices. If you can’t track where you stand week over week, something’s off.
- Look for pre-CMMC history: Firms that built their practice around cybersecurity compliance before CMMC came along have seen more, fixed more, and tend to handle edge cases better than those who pivoted into this space recently.

We’re including ourselves so you know who’s making these recommendations. After nearly 30 years serving small and mid-sized businesses across Virginia and DC region, we’ve built deep expertise in cybersecurity and IT management.
