As investments in AI-ready data centres continue to accelerate worldwide, the Security Industry Association (SIA) has released a new Data Centre Physical Security Principles Guide.
The document offers a practical framework to help operators strengthen the physical protection of critical digital infrastructure.
The guide arrives at a time when hyperscale facilities, colocation providers and enterprise data centres are expanding rapidly to support growing demand for artificial intelligence (AI), cloud computing and digital services.

Industry Guide Focuses on Protecting Sensitive Infrastructure
Developed by SIA’s Data Centre Advisory Board, the publication outlines the core principles organisations should consider when designing, operating and upgrading physical security for data centres.
Rather than concentrating solely on cyber threats, the guide highlights risks that originate in the physical world. These include unauthorised access, insider threats, theft, vandalism and disruptions that could affect business continuity.
The document suggests a layered security approach that combines perimeter protection, access control, surveillance, visitor management and continuous monitoring. It also encourages operators to integrate physical security into the overall design of a data centre instead of treating it as an afterthought.

Growing AI and Cloud Demand is Reshaping Security Priorities
SIA said the rapid expansion of AI workloads and cloud infrastructure is changing the way data centres are planned and managed. While much of the industry’s attention has been on power availability, cooling capacity and sustainability, the association argues that physical security is equally important as facilities become more critical to national digital infrastructure.
According to the report, global data creation is expected to reach 181 zettabytes in 2025, representing a 23% year-on-year increase.
This translates to roughly 2.5 quintillion bytes of data generated every day, or nearly 29 terabytes per second, underscoring the scale at which modern data centres now operate.

The Guide Aims to Support Long-Term Resilience
The association said the guide is intended for security professionals, consultants, system integrators and data centre operators responsible for protecting mission-critical facilities. It also discusses the importance of interoperability between security systems, lifecycle planning and collaboration between technology vendors and infrastructure operators.
As governments & businesses continue investing in AI infrastructure and cloud services, industry bodies expect physical security to become an increasingly important part of data centre resilience strategies.
