About GreylineOps

We built GreylineOps for the small businesses that keep this country’s defense contracts running — and that Washington keeps forgetting about. When CMMC 2.0 enforcement went live in November 2025, large defense primes had entire compliance teams ready. Small businesses — the subcontractors, the specialized manufacturers, the two-person engineering shops holding sensitive government contracts — were largely on their own. That’s the gap we exist to close. GreylineOps is a veteran-owned managed IT and compliance firm operating 100% remotely across the United States. Our team has served in uniform, and we bring that same sense of mission and accountability to protecting your business and your contracts.

Our Specialty: CMMC Level 3

Most MSPs can help you check a compliance box. We specialize in preparing small businesses for CMMC Level 3 — the most rigorous tier of the Cybersecurity Maturity Model Certification framework, required for contractors handling the DoD’s most sensitive Controlled Unclassified Information (CUI). Level 3 compliance isn’t just paperwork. It requires implementing 24 additional security controls beyond Level 2, aligned with NIST SP 800-172, and is assessed directly by the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC). Phase 3 enforcement begins in November 2027 — which means your window to prepare is now, not later. Not every client we work with needs Level 3 — and we’ll tell you honestly if you don’t. But if you do, we’re one of the few MSPs in the country that truly specializes in getting small businesses there.

Remote-First. Nationwide.

We’re not limited by geography. Our remote-first model means we can serve defense contractors from San Diego to Huntsville to Northern Virginia with the same consistency and responsiveness. Whether you’re a prime contractor or a subcontractor in the supply chain, we meet you where you are.

Veteran Owned. Mission Driven.

Our founders wore the uniform. We understand what’s at stake when sensitive information isn’t protected — not just contractually, but nationally. That perspective shapes everything we do, from the way we assess your environment to the way we communicate with your team. We don’t oversell. We don’t overpromise. We tell you exactly where you stand, what it takes to get compliant, and we do the work alongside you.

Who We Work With

GreylineOps works with small businesses that hold or are pursuing DoD contracts — typically companies with 5 to 150 employees who handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) and need a trusted partner to navigate CMMC requirements without building an in-house IT and compliance team.
