Nation-Scale Resilience: Defending Internet Infrastructure from AI-Accelerated Threats

Ransomware 3.0, AI-generated zero-days and state-directed BGP hijacks are no longer isolated events—they are converging into “kill-chain cocktails” capable of darkening a nation in minutes. The June 2025 CISA alert on Iranian-linked campaigns against critical infrastructure and the retail breach that erased £700 million in value overnight are only the latest warnings. This talk distils front-line lessons from Blindspot’s work securing Tier-1 ISPs, energy grids and government backbones on three continents. We dissect real breach timelines, expose where perimeter and single-provider models failed, and demonstrate how layered AI-driven anomaly hunting restored service inside SLA windows. Attendees leave with an actionable, vendor-agnostic playbook to harden national access networks before the next “0-day” hits.

Key take-aways

• Architecture patterns for sovereign, tamper-proof routing and DNS
• Board-ready metrics proving resilience is a growth lever, not a cost center
