Today I’m sharing an exciting and important update about Security 101’s next chapter. Investment funds managed by Morgan Stanley Capital Partners (MSCP), the middle market private equity buyout team within Morgan Stanley Investment Management, have acquired Security 101. This partnership strengthens our ability to exponentially scale the platform while reinforcing the execution, consistency, and experience our customers rely on.
Security 101’s growth has been fueled by a best-in-class team with a fanatical approach to customer satisfaction. This is a team that demonstrates consistency and excellence in designing engineered solutions, managing comprehensive projects end-to-end, and providing reliable and responsive service on a platform built to support customers operating across complex environments. As customer demand increases for integrated systems that must perform consistently across multiple sites and operate securely on modern IT networks, we remain committed to raising the bar for what customers can expect from a commercial security integrator.
A continuation of the strategy, with added resources
Our strategy is not changing. We will continue to operate with the same focus on disciplined execution in local markets, paired with the platform strength required to serve multi-site customers and national accounts. This partnership adds resources and support to accelerate priorities that are already core to our business, including:
-
Elevating the customer experience across every market we serve
-
Scaling service delivery and consistency across both local and national environments
-
Strengthening our national accounts program through process and platform investment
-
Continuing thoughtful M&A that expands coverage and capability in ways that benefit customers
-
Investing in systems, infrastructure, and enablement that support long-term performance
Partner perspective
Commenting on the investment, Adam Shaw, Managing Director and Head of Business Services at MSCP, said:
“Security 101 has built a differentiated platform with a strong record of organic growth and consistent execution across complex customer environments. We are excited to partner with Greg and the broader team to support continued expansion and further strengthen the Company’s leadership position. We intend to continue investing in the platform to further elevate the customer experience and support scalable service delivery across both local markets and national accounts.” |
A statement from me
“We’re excited to team up with Morgan Stanley Capital Partners to build on our momentum and extend Security 101’s leadership in commercial security integration. MSCP’s resources and experience will help us deepen our national accounts program, continue thoughtful M&A, and expand our unified platform while maintaining the culture and consistency our customers expect.” |
What this means for customers and partners
Security 101 will continue operating under the same brand and leadership focus, with day-to-day execution led by the same local teams who serve customers today. Our priority remains straightforward: deliver engineered, field-proven security solutions and back them with responsive service.
Customers can continue to expect Security 101 to design, install, and maintain integrated electronic security systems for commercial organizations that require reliability, accountability, and consistent performance across diverse environments.
Looking ahead
The commercial security market continues to evolve quickly. Customers are asking more of their systems and more of their integration partners. They need solutions that scale, service delivery that is consistent, and a partner that can support both local execution and national expectations.
This partnership is designed to help us meet that demand, continue expanding responsibly, and further strengthen Security 101 for customers, partners, and TEAM101.
