July 15AI Doesn't Break Security. It Exposes It. | Jason Garbis
Most security breakthroughs don't come from new technology, they come from finally getting the basics right. As AI accelerates both attacks and the pace of vulnerability disclosure, the organizations that fare best aren't the ones chasing the next big thing, but the ones with the visibility, governance, and segmentation to absorb the shock.
In this episode, Raghu Nandakumara sits down with Jason Garbis, founder and CEO of Number Line Security and co-chair of the Zero Trust Working Group at the Cloud Security Alliance, to explore what Zero Trust looks like when threats evolve at machine speed.
Jason draws on his path from early software-defined perimeter work to leading Zero Trust strategy at the Cloud Security Alliance, sharing why "right-sizing" a Zero Trust initiative matters more than chasing sweeping transformation, and why even a well-built security capability fails without genuine buy-in from the business.
The conversation then turns to AI's effect on the threat landscape: the surge of vulnerabilities and patches enterprises now have to absorb, the widening gap between attacker speed and defender response, and why segmentation remains one of the most effective ways to shrink the blast radius of an attack.
Raghu and Jason discuss:
How to right-size a Zero Trust initiative for an organization's actual readiness

Why "build it and they will come" doesn't work for security adoption

Tying Zero Trust investments to business priorities like AI adoption, M&A, and compliance

What's genuinely new — and what isn't — about securing AI systems and agents

How accelerating vulnerability disclosures are reshaping patch management

Why segmentation reduces blast radius even when patching can't keep pace

A simple analogy for explaining zero trust to non-security stakeholders
Jason closes with his go-to way of explaining Zero Trust to non-technical stakeholders: an analogy involving brakes, oil, and seat belts that reframes security as a shared responsibility rather than a roadblock.

June 17The Cybersecurity Cliff Nobody Is Talking About | Jen Ellis
In this episode, Raghu Nandakumara sits down with Jen Ellis, founder of NextJenSecurity, for a sharp and wide-ranging conversation about why so many of cybersecurity's biggest debates keep missing the point.
Just weeks after a major AI breakthrough sent shockwaves through the security industry, Jen brings her trademark candour to the questions everyone is asking: from the real mechanics of ransomware economics to a frank assessment of why the industry's approach to resilience may be fundamentally miscalibrated.
The conversation explores what it actually means to defend in an era where vulnerability discovery is accelerating faster than vendors can patch, end users can respond, and policymakers can keep up. Jen argues that while the threat landscape has never been more urgent, the assumptions underpinning most proposed solutions, from payment bans to AI-powered fixes, are more naive than the industry wants to admit.
Raghu and Jen discuss:
Why banning ransom payments won't end ransomware — and what a responsible policy glide path might actually look like

How ransomware targeting really works, and why the "cut off the revenue stream" argument misreads the threat

Why the vendor response piece of the AI vulnerability pipeline is being dangerously overlooked

The legacy technology time bomb — and why developed economies are most exposed

Why being trusted and being trustworthy are not the same thing

What cyber insurance gets right, and why it isn't ready to save us yet

Why there are no five-step fixes — and why pretending otherwise is part of the problem

How the current moment of political and regulatory urgency may be the industry's best chance to act
The episode closes with a dose of honest pragmatism: there are no five-step fixes, nothing is actually simple, and the attack surface is expanding faster than most organizations are moving. But there is real momentum — more policymakers, more collaboration, more urgency than the industry has ever seen. The question is whether we'll use it.

June 03Same Problems, Different Decade | Dr. Anton Chuvakin and Erik Bloch
In this episode, Raghu Nandakumara sits down with two heavyweights in cybersecurity: Dr. Anton Chuvakin (Google Cloud) and Erik Bloch (Illumio), for a candid, often funny, and occasionally sobering look at why detection and response keeps fighting the same battles it was fighting 20 years ago.
From the birth of SIEM and the coining of "EDR," to the short-lived reign of XDR, to today's AI hype cycle, Anton and Erik trace the full arc of the industry's evolution and interrogate why, despite decades of tooling investment, the fundamental outcomes haven't changed.
Alert fatigue, signal-to-noise ratios, and the needle-in-the-haystack problem remain as stubborn as ever –and the slides security teams are building in 2025 look suspiciously like the ones from 2003.
Raghu, Anton, and Erik discuss:
Why the SOC still largely runs on a 1990s operating model and what it would actually take to change that

How compliance pulled SIEM away from detection for over a decade and why that hangover still lingers

Why a handful of engineering-led organizations (Google, Netflix, a European bank) have cracked the code while nearly everyone else keeps applying band-aids

The pharmaceutical industry analogy that explains why security startups keep building band-aids instead of solving root causes

What MDRs are doing right and why enterprise SOCs have no incentive to learn from them

Why AI is accelerating tooling but, for some organizations, actually slowing down the harder transformation work

How securing AI is repeating the exact same mistakes made in the early days of cloud
