Security leaders are navigating a threat environment that looks very different from a year ago. The attack surface keeps expanding, but the real shift is speed. Generative AI has changed how attackers operate — network mapping, vulnerability targeting and lateral movement that once took weeks now happen in minutes. Adversaries move faster than ever, while defenders are still expected to move carefully, manually, and without error.

​

Most security stacks weren't built for this. Legacy perimeter defences, static firewall rules and fragmented visibility slow defenders down without slowing attackers, widening the gap between threat activity and response.

​

The unspoken shift is that "prevent every breach" stopped being the goal some time ago. The harder question now is: when an intruder is already inside, how do you make sure it doesn't matter very much?

​

This invitation-only roundtable brings senior UK security leaders together for a candid, peer-driven conversation on how microsegmentation, real-time visibility and machine-speed operations are being used to contain breach impact — and where they fall short. A small room. Senior peers. Honest dialogue.

​

Discussion Themes:

​

1. Microsegmentation in an AI-accelerated threat landscape — what's working, what's not

2. Real-time visibility without operational drag — separating signal from noise

3. Security operations at machine speed — what stays human, what gets automated

​

What You'll Take Away:

 

• How peers are sequencing their containment investments under real budget constraints

• Where AI-accelerated attacks are landing in UK enterprises right now, and what's stopping them

• A small, candid network of senior security leaders working through the same problem
