Agentic Risk: Compromised Agents and Kernel Controls

Show Description

Joe Levy is the CEO of Sophos and a 30-year cybersecurity veteran who has held technical and executive roles across some of the industry's most recognizable brands. In this episode, we dig into a stat that should reframe how the entire industry thinks about its mission: out of roughly 359 million businesses worldwide, fewer than 32,000 have a CISO. That's less than one in 10,000 organizations with a security strategy leader — and it's a number Joe worked with Cybersecurity Ventures to quantify for the first time.

We explore what that structural gap means for how vendors build products, why the cybersecurity market is a 40-year-old market failure where spending goes up every year but outcomes don't improve, and how Sophos is betting that agentic AI can deliver CISO-level intuition to the hundreds of millions of organizations that could never conceive of hiring one. Joe breaks down where AI is genuinely delivering in security operations — and where the industry is overselling — drawing from Sophos's experience running the world's largest MDR service with 36,000 customers.

We also get into Sophos's Pacific Rim disclosure, a five-year engagement with a Chinese nation-state actor targeting their firewalls that Joe calls the highest form of threat intelligence sharing. He walks through the calculus of going public with that story, including the kernel-level monitoring they deployed on a handful of devices to stay one step ahead of the attacker. Plus, we discuss the SecureWorks acquisition, the CTO-to-CEO transition, competing with hyperscalers like Microsoft, and what the next chapter looks like for a billion-dollar PE-backed security company approaching maturity with Thoma Bravo.

Show Notes

• The cybersecurity poverty line quantified: out of 359 million businesses worldwide, fewer than 32,000 have a CISO — less than one in 10,000 — and this leadership gap compounds with the skills shortage and what Joe calls an "AI-enhanced market for lemons" where information asymmetry between buyers and vendors is getting worse
• The real problem isn't missing technology — most organizations already have endpoints and firewalls — it's misconfigurations, ignored alerts, undeployed agents, and no SOC to respond, which is why secure-by-default design and hybrid product-service models like MDR create more predictable outcomes than tools alone
• AI in the SOC is overhyped but not hype: Sophos runs 36,000 MDR customers and says the vast majority of Tier 1 (triage, false positive management) and Tier 2 (investigation, response) can now be performed by agents — but the industry lacks standard vocabulary for metrics like MTTR, letting vendors be "intentionally opaque" about what "response" actually means
• Joe introduces the concept of "humans as the accountability API" in an agentic world — AI can approximate analyst intuition, but someone still needs to be held accountable for remediation decisions, and a fully autonomous SOC may just be "a protection product with a very long data pipeline"
• The Pacific Rim story: Sophos spent five years engaged with a Chinese nation-state actor targeting their firewalls, deployed a kernel implant on fewer than a handful of attacker-controlled devices to observe exploit development in real time, and concealed targeted fixes among 150 other patches to avoid tipping off the adversary
• Sophos's CISO Advantage program aims to deliver the intuitions of a skilled security leader to the hundreds of millions of organizations that could never hire one — Joe calls it fixing a 40-year-old market failure and says they're shipping it this year
