In perimeter security, partnerships are not built by announcements alone. They are built over time through trust, execution, and the ability to deliver when it matters most.

This year marks 15 years of partnership between Solid Security and Gallagher Security. That relationship has been shaped by a shared commitment to protecting people, property, and critical infrastructure with solutions designed to perform in the real world.

For Solid Security, perimeter security is not one division among many. It is the focus. It is the work the company was built around, and it is where its experience runs deepest. For customers, that matters. Perimeter security demands more than product knowledge. It requires understanding site conditions, operational needs, risk points, system integration, and long-term performance. It also requires understanding that no two sites are exactly alike.

Customer needs vary, risks vary, and the right solution is rarely one-size-fits-all. That kind of judgment comes from real field experience.

That is where Solid Security has built its reputation.

Over the past 15 years, Solid Security has worked alongside Gallagher to help organizations implement perimeter solutions that do more than check a box. The goal has always been to provide systems that are thoughtfully designed, properly installed, and supported long after the initial project is complete. That level of consistency is what turns a working relationship into a lasting partnership.

At the center of that success is Tom O’Brien and the team he has built. Tom’s approach has never been about high-pressure selling. It has always been about understanding what the customer truly needs and helping them arrive at the right solution. That service-first mindset, combined with Tom O’Brien’s extensive knowledge and deep real-world experience in perimeter security, has earned trust across the industry and helped Solid Security grow through strong relationships, proven results, and long-term customer trust.

Customers value working with specialists who understand the unique demands of perimeter

protection. They want a partner who knows how to assess risk, understand the customer’s needs, recommend the right approach, and stand behind the solution. That is exactly what Solid Security has done with Gallagher systems and with the customers who depend on them.

In an industry where new alignments and new names will always emerge, experience still matters. Focus still matters. Performance still matters.

Some partnerships are new. Others are proven.

For 15 years, Solid Security and Gallagher Security have built a partnership through real work, real projects, and real results. That history is worth recognizing, and it is only one part of what continues to drive the relationship forward.

Solid Security remains committed to the same principles that built that partnership from the start: deep perimeter expertise, trusted execution, and a genuine commitment to helping customers secure what matters most.

After 15 years, that foundation is stronger than ever.
