Modern data centres currently invest most of their resources into perimeter security. They install biometric entry systems, CCTV, mantraps, and have guarded access points. These controls are essential. However, these tools alone cannot guarantee total safety in a complex digital age. A secure perimeter only stops the initial threat. Once an individual steps past the front desk, the nature of the risk changes completely.  The real question then becomes: what can they access—and how is that access controlled, monitored and audited? The Overlooked Risk: Insider Threats and Shared Environments Today’s data centres have moved beyond private, single-user environments. Instead, colocation and hybrid setups mean that engineers, contractors, and vendors now work side-by-side in the same rooms. However, this shared access creates dangerous security gaps: Rising Insider Threats: People may cause harm, whether by mistake or on purpose. Blurred Ownership: Multiple users make it hard t...
