For decades, cybersecurity strategy has revolved around a shared assumption: zero-day vulnerabilities are rare, expensive to find, and difficult to exploit at scale. That assumption is now breaking down. The emergence of Mythos, the advanced AI system developed by Anthropic, marks a turning point in how vulnerabilities are discovered, weaponized, and defended against—and it forces security leaders to rethink long-held priorities.

With phased enforcement commencing, contractors face a tightening timeline to prove compliance. Those who mobilize early will stay ahead of deadlines and avoid potential bottlenecks.

Artificial intelligence is no longer an emerging force in cybersecurity; it is the defining one. In 2026, organisations will face AI-driven attacks that move faster, scale wider and exploit vulnerabilities in hours rather than weeks. At the same time, defenders are increasingly turning to AI to regain the advantage.

For years, cyber resilience has been treated as a collection of loosely connected disciplines: security teams focused on prevention, identity teams guarded access, and backup teams planned for recovery. In 2026, that fragmented approach will no longer be viable.
