The global data center market is expanding at an unprecedented pace. In 2025, the world will generate 181 zettabytes of data—an increase of 23% year over year. That translates to 2.5 quintillion bytes created every day: 29 terabytes every second. This explosive demand for storage and processing fuels the industry’s relentless focus on power and cooling. Yet while those conversations dominate, physical security remains in the back seat—even though it is equally critical to resilience. At the same time, the surge in demand is reshaping the market with hyperscale growth, colocation competition and enterprise expansion.
With rapid growth comes new complexity: outdated specifications, siloed security systems and partners experienced in other markets yet unfamiliar with the unique demands of data centers—all of which threaten the resilience of critical digital infrastructure.
This paper, authored by Amy Dunton, co-chair of the SIA Perimeter Security Subcommittee and managing partner at Sulton Security, examines the challenges shaping physical security for data centers today, with a focus on integration, interoperability and life-cycle management. Drawing from manufacturers, integrators and end users, it highlights not only emerging technologies but also the persistent risks of treating security as an afterthought. The result is a forward looking roadmap to deliver resilient security that enables, rather than hinders, growth.
