Cybersecurity Has Hit a Brick Wall — Andrew Rubin on What Comes Next

In this episode, Raghu Nandakumara sits down with Andrew Rubin, Founder & CEO of Illumio, for a candid conversation about the next phase of AI-driven cybersecurity risk.

Just weeks after a major AI breakthrough sparked shockwaves across the security industry, Andrew shares his immediate reaction — from the sobering implications of machine-speed vulnerability discovery to a frank assessment of why the cybersecurity industry's fundamental model may already be broken.

The conversation explores what actually changes in an era where vulnerabilities could be discovered and exploited faster than any human-driven operation could manage. Andrew argues that while segmentation as a concept is decades old, its role as a critical backstop has never been more urgent. If attackers begin operating at machine speed, defenders must rethink not just their tools, but their entire operating model — from how they assess risk to how quickly they can respond.

Raghu and Andrew discuss:

• Why the cybersecurity industry has spent more every year while outcomes have gotten worse
• How AI creates an asymmetric threat unlike anything defenders have faced before
• Why patching alone won't solve the problem — and the COVID vaccine analogy that explains why
• The shift from prevention to resilience as the new security north star
• What the SolarWinds story reveals about how organizations miscalculate tail risk
• Why segmentation becomes one of the few reliable backstops in a model-driven world
• How the era of 12-month RFPs and POCs may be coming to a swift and necessary end
