Great show
The content is great for analysis. One suggestion as a listener though - Andy can get pretty arrogant and be quite confidently incorrect in some of his generalized blunt statements.

Talking Points

Recent interactions between the hosts and their guests.

I Sent the AI a Strongly Worded Prompt. I Think We'll Be Fine.

Q: Where do the blockades come in, Chad? Is it another AI tool that has a goal of blocking another AI from bad behavior as it tries to achieve its goal?

Rubin recommends defense in depth, including least-privilege permissions, agent orchestration and quality checks, properly scoped MCP access, AI gateways, prompt and data monitoring, proxies, identity monitoring, and zero-trust boundaries.

I Sent the AI a Strongly Worded Prompt. I Think We'll Be Fine.

Q: Can AI be approached this simply as Alan puts it out? What do frameworks look like?

Ellis says solving AI risks is not simple, but getting started is: organizations can begin with discovery and governance for shadow AI and practical support for employees building with AI. Rubin agrees that starting promptly matters and says AI can help address patching, vulnerability remediation, and legacy-code challenges.

Why Should AI Give You Back Time When It Could Just Replace You?

Q: Do you think vendors are selling the capability with their tools, or are they selling headcount reduction?

Landegger says AI is increasingly framed as a way to allocate attention and let teams focus on higher-priority work, not eliminate staff. Combs describes the need to help security teams scale amid a growing volume of incidents.

Why Should AI Give You Back Time When It Could Just Replace You?

Q: How do you determine when something is a structural issue versus a coding issue?

Combs recommends looking for recurring fixes, patches, and changes in an application's scale or purpose, then reviewing its architecture periodically. Landegger adds that growing organizations need clear accountability for examining systems across team boundaries.

BONUS EPISODE: Super Cyber Friday Express - Hacking Vendor Selection

Q: Three variables that are like a top of your list when evaluating vendor. And by the way, I should mention that Karl has been on both sides of the aisle and Howard, I don't think you've worked for a vendor, but you've worked for an analyst and you have worked for a vendor.

Karl and Howard discuss key evaluation criteria: architectural consistency and usability, pricing, industry reputation, quality of service, and whether the vendor can actually support and enable the buyer's team to use the product effectively.
