Security Weekly Podcast Network (Audio)

The threat landscape has become more interconnected, disruptive, and complex. Ransomware is now as much about extortion and data theft as it is about encryption. Supply chain events can create outages that ripple far beyond the initial target, and business interruption increasingly comes from third-party and cloud dependencies. How should CISOs prepare for these scenarios?
Dan Bowden, Global Business CISO at Marsh, joins Business Security Weekly to discuss how to connect cyber risk to the outcomes boards care about most: resilience, financial exposure, regulatory impact, and reputation. CISOs need to position cyber as an enterprise risk, not a technical risk, that can be measured, prioritized, and managed alongside other strategic risks. Dan will discuss the results of Marsh's Cyber Catalyst research and Global Cyber Claims Report.

The Agent Is the New Insider: Why Human Risk Doesn't Stop at People: Black Hat Interview with Leslie Nielson, CISO at Mimecast
AI agents now act with the same credentials and access as the humans who deployed them, but without the judgment or accountability that comes with actual employment. Mimecast CISO Leslie Nielsen argues that treating agentic AI as a brand new, standalone security category is the wrong instinct: agents are an extension of human risk, and the controls organizations already use to manage people are the right foundation for managing machines. In this conversation, Nielsen unpacks the growing gap between security leaders who expect AI driven attacks and those who feel prepared for them, and what that gap means for CISOs walking the floor at Black Hat.

Ransomware Moves up the Org Chart: Managers Are Prime Targets: Black Hat Interview with Brett Stone-Gross, Sr. Director, Threat Intelligence at Zscaler
When a ransomware attack makes headlines, attention usually turns to the organization that was breached, the systems encrypted, data stolen, and disruption or ransom demand that followed. Less, if anything, is revealed about the employees compromised at the start of the attack, and what makes those individuals valuable targets.
New Zscaler ThreatLabz research examines this early stage of a real-world ransomware attack. ThreatLabz identified victims of a campaign associated with a ransomware group known for gaining initial access, stealing large amounts of corporate data, and selectively encrypting critical systems. The findings show who those victims were and how their roles and authority could help an attacker move deeper into an organization.
This is part of ongoing ransomware research by ThreatLabz. The Zscaler ThreatLabz 2026 Ransomware Report, coming in the next two months, will include additional data on ransomware victims, the latest ransomware trends, targets, and tactics, and the risks enterprises should prepare for next.

Sandboxing, least privilege, and monitoring are well-established controls in terms of the defenses they provide against unexpected and unauthorized actions. But being well-established in theory doesn't always translate to successful in practice. Kieran Human talks about some of the properties that a good sandbox should have and how monitoring creates a feedback loop to refine allow lists and access controls. In practice, the potential unpredictable behavior of an agent isn't much different from malware. We talk through some of the ways orgs can securely deploy agents without unnecessarily increasing their attack surface.

Interview with Rob Allen from Threatlocker
Safely enabling agentic AI for Businesses
OpenClaw was the wakeup call and businesses wanted to know how to block it. “Easy,” Rob Allen said, “it’s already blocked if you’re using Threatlocker.” Now that things have settled down a bit, those same businesses want to allow their employees to experiment with agents. We discuss how they can do it safely.
