OTHSolutions Achieves CMMC with a Perfect 110/110 CMMC Score

Faced with increasing federal requirements and OASIS+ pressure, OTHSolutions set out to achieve CMMC compliance. When new business opportunities arose requiring CMMC, they enlisted MainSpring and PreVeil to expedite the process—achieving CMMC in under 1 year with a perfect 110 score in their C3PAO assessment.

As a user of PreVeil, the experience has been fantastic. Very intuitive and very easy to implement on our end.

When OASIS+ required a validated plan to protect Controlled Unclassified Information (CUI), OTHSolutions knew they needed a compliant communication and collaboration system along with a documented, repeatable cybersecurity program.

With the advice of their MSP partner, MainSpring, OTHSolutions decided to get their CMMC certification to expand their go-to-market strategy to include Defense Industrial Base (DIB) contractors.

Starting from ground zero, OTHSolutions wanted to avoid over-engineering the solution or overspending.


OTHSolutions looked to MainSpring as their MSP and advisor to build a practical, cost-effective path to certification. MainSpring delivered everything they needed including:

  1. The initial gap assessment
  2. Creating a security roadmap
  3. Recommending and implementing a compliant tech stack
  4. Preparing documentation for the C3PAO assessment

MainSpring took time to understand what we truly needed. They built a perfect-fit plan—nothing more, nothing less.

MainSpring recommended PreVeil as the best-fit solution for storing and protecting CUI.

OTHSolutions chose PreVeil because it was:

  1. Extremely easy to use
  2. More flexible and affordable than GCC High
  3. A secure enclave that met CUI requirements
  4. Lightweight to deploy and manage

“Companies need a solution that fits them well today while being able to grow with them to meet their requirements 10 years from now. We want to make sure we’re making the right decision and investing in the right solution for each client, and PreVeil happened to be that.

Today, OTHSolutions uses PreVeil for both secure email and file sharing, supported by a Microsoft Defender-based security stack.

OTHSolutions officially passed its C3PAO assessment in November 2025. OTHSolutions worked with StrategicIT Solutions as their C3PAO based on their experience with PreVeil and their practical approach. The whole process took less than 9 months from the kickoff call CMMC was first brought up on to being L2 Certified.


  • Eligible for OASIS+ and CMMC-related opportunities
  • Increased competitiveness in federal contracting
  • Repeatable, predictable compliance process
  • Improved security posture
  • Confidence that future audits will be manageable

“It was easy for us because MainSpring did all the heavy lifting. I was trying to run a business, and Mainspring took the bull by the horns so I didn’t have to do much at all. They did everything for us and helped us get there.

OTHSolutions’ journey shows that:

  • CMMC compliance doesn’t have to be expensive or overwhelming
  • The right partner and tech stack make certification achievable
  • PreVeil’s enclave approach minimizes change and simplifies audits
  • A well-coordinated team (MSP + PreVeil + C3PAO) determines success

OTHSolutions is now positioned for expansion—and willing to serve as a reference for other SMBs beginning their CMMC journey.


PreVeil provides a clear path to CMMC compliance solution for defense contractors, proven in over 75 CMMC assessments at a fraction of the cost of alternatives.
