Case Study: Supporting Pendar Technologies Through a Successful CMMC Assessment
The Challenge
As a subcontractor to the U.S. Department of Defense, Pendar Technologies undertook a CMMC assessment that required sustained coordination and focus across the organization throughout 2025. To support this effort, Pendar partnered with Mainstay Technologies for guidance and execution throughout the process. As Pendar’s leadership described it, the effort involved “substantial documentation work alongside many fast-paced technical control projects,” a reality that shaped both the pace and complexity of the engagement.
The Mainstay Approach
Mainstay partnered closely with Pendar throughout the engagement, providing structured guidance, hands-on documentation support, and technical leadership to help navigate the CMMC landscape. Ajdin Hasanefendic-Carroll, IT Manager at Pendar, highlighted the importance of leadership and clarity during the process, noting that Mainstay’s guidance “made a complex and unfamiliar landscape not only manageable, but constructive and growth oriented”. Mainstay’s team worked collaboratively with Pendar to ensure every requirement was addressed with rigor and precision. As Ajdin shared, “The professionalism, integrity, and dedication each of you demonstrated reflects the highest standards I have come to expect in mission-critical work”.
Execution and Collaboration
Throughout the engagement, Mainstay emphasized partnership and accountability. Pendar’s leadership consistently pointed to the value of this approach during the most demanding phases of the assessment. Romain Blanchard, Chief Operating Officer at Pendar Technologies, shared that Mainstay’s “consistency, responsiveness, and depth of expertise were critical in helping us navigate the process successfully” and that “we landed exactly where we needed to, and we are very satisfied with the outcome”. The engagement was characterized by close coordination, trusted communication, and sustained effort on both sides. As Ajdin noted, Mainstay’s support created “a collaborative environment rooted in trust and mutual respect, which made even the most demanding moments feel aligned and achievable”.
Results & Looking Ahead
Pendar successfully completed its CMMC assessment, meeting its compliance objectives and strengthening its security posture in support of Department of Defense requirements. Reflecting on the outcome, Romain stated, “We greatly value this partnership and appreciate the level of care and commitment you brought to this effort”. Ajdin echoed that sentiment, adding, “Thank you all for your partnership, your support, and the impact you have made. It has been a privilege to work alongside you, and I look forward to what the future brings”. With a successful assessment complete, Pendar and Mainstay are positioned to build on this foundation over the coming years. As the organization continues to evolve its security and compliance posture, the relationship established during this engagement sets the stage for continued collaboration and long-term success.
