The Fundamentals of Data Center Security: A New Era of Distributed Defence
6:00 - 8:30 PM CesT | Brussels, BElgium
Event Overview
The data centre is no longer a fixed, physical environment. It now extends across public and private clouds, edge locations, and containerised workloads. This shift has blurred the perimeter and redefined what must be secured, and how. Security teams face uneven visibility, inconsistent policy enforcement, and increasing operational complexity as workloads and identities move fluidly between platforms.
This closed-door roundtable will explore how to build and operate security architectures fit for this distributed reality. We’ll focus on turning hybrid mesh firewalls and microsegmentation into practical controls, and on aligning security policy across Kubernetes clusters, multi-cloud environments, and legacy systems without adding friction.
Among the discussion topics:
Establishing consistent segmentation and visibility across hybrid and containerised workloads
Operationalising hybrid mesh firewalls and addressing tool fragmentation
Securing AI workloads and understanding where model exposure begins.
Rethinking defence strategies as applications and attack surfaces evolve.
