Gallagher Security Expands – Gallagher Security has expanded its longstanding partnership with cyber-physical solutions provider M.C. Dean through a new strategic solutions partner agreement.
According to Gallagher’s chief executive officer, Mark Junge, this marks a significant evolution in the relationship, enabling deeper global collaboration and extending Gallagher’s footprint across mission-critical environments worldwide.
Headquartered at Tysons Virginia and with an Australian office in Melbourne, M.C. Dean designs, builds, operates, and maintains cyber-physical solutions for the world’s most recognizable mission-critical facilities, secure environments, complex infrastructure, and global enterprises.
Since 2016, Gallagher and M.C. Dean have partnered to deliver trusted security solutions across some of the world’s most complex and secure environments. The decade-long partnership has been built on technical alignment, shared values, and a mutual commitment to protecting people, assets, and critical infrastructure.

This renewed strategic focus reflects the strength and maturity of that relationship, elevating collaboration to support M.C. Dean’s global operations across the Americas, EMEA, and APAC. Moving forward the organizations will work more closely to deliver integrated, cyber-physical security solutions designed for scale, resilience, and long-term performance.

It reflects the confidence we have in each other and our shared commitment to delivering intelligent, resilient security solutions on a global scale.”
From Gallagher’s perspective, the expanded partnership strengthens its ability to support large-scale, mission-critical deployments through partners who operate at the highest levels of complexity and assurance.
“This agreement reinforces our confidence in the work we do together and the environments we support,” says Jeff Fields, director of Federal Programs – Americas at Gallagher Security.
“M.C. Dean understands what it takes to deliver in high-consequence, mission-driven settings. This next phase of our partnership ensures we’re even better aligned to support customers who demand reliability, security, and long-term performance.”
According to Julaine Simmons, senior vice president of M.C.
