Business Reporter: Resilience should be achieved through risk containment

The role of effective segmentation and AI-powered detection and response after the release of Mythos

LONDON, UNITED KINGDOM, September 11, 2026 /EINPresswire.com/ -- In an article published on Business Reporter Andrew Rubin, Founder and CEO of Illumio explains why Mythos and other frontier AI models are shattering cyber-security’s operating model and why resilience is the only way forward. The assumptions that have guided cybersecurity for decades are no longer fit for purpose. As artificial intelligence accelerates both attack and defence, organisations must shift from preventing every breach to containing inevitable compromise through resilience, segmentation and intelligent response. Mythos “didn’t just raise the stakes,” Rubin says. “It changed the rules.” The old equilibrium assumed defenders had time and attackers faced technical barriers. AI has erased both assumptions, democratising sophisticated exploits while dramatically increasing the speed of attacks.

AI also offers the potential to generate security patches automatically but deploying them safely at enterprise scale remains a significant challenge. Organisations must validate compatibility, avoid disrupting critical systems and manage millions of unique environments before automated patching can become routine. The Hard Truths in Cybersecurity panel at the 2026 RSAC Conference featuring SolarWinds’ CISO during the 2020 supply-chain compromise highlighted the potential consequences of overreliance on perimeter defences and demonstrated that prevention alone can’t be a winning strategy. The future of cybersecurity lies in resilience achieved through breach containment, enabled by effective segmentation and AI-powered detection and response. However, “segmentation doesn't need to be perfect," Rubin maintained. "It simply needs to reduce risk significantly by limiting how far an attacker can move." Rather than building ever-higher walls, organisations should focus on rapidly identifying, isolating threats and recovering from the attacks that inevitably penetrate their defences.
