In this deep dive, Stephen returns to break down the rapidly evolving landscape of AI in cybersecurity. We explore the critical differences between offensive AI (using AI to enhance attacks) and adversarial AI (attacking the AI models themselves). Learn the mechanics behind prompt injection, LLM jailbreaking, and how vector databases are structured. We also analyze real-world case studies, including Google Project Zero's Big Sleep autonomous zero-day agent, and demonstrate how new AI-driven tools are being used for patch diffing and root cause analysis. Finally, we tackle the massive industry question: will AI replace human penetration testers, and what steps should you take right now to futureproof your tech career? Plus, a quick look at how automated agents are tackling API vulnerabilities like BOLA. // Stephen's Social // Twitter: / steph3nsims YouTube: / @offbyonesecurity Discord: / discord // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

He cuts through the marketing hype and explains why relying solely on AI to block attacks is not a solution to all our cyber problems. We also discuss modern threats—including the rise of Agentic AI—and why determining the "intent" of software is practically impossible for artificial intelligence. Instead of chasing the latest buzzwords, learn the foundational, proven strategies to actually secure your network. We dive deep into Zero Trust Network Access (ZTNA), the power of default deny, and the specific, tangible controls you need to block ransomware, prevent Office 365 phishing, and stop bad actors.

Big thanks to Cisco for sponsoring this video and sponsoring my trip to Cisco Live Amsterdam 2026. In this deep dive, David Bombal sits down with Carlos Pereira (Cisco Fellow & Chief Architect, Customer Experience) to discuss the hard truth about AI deployment in 2025 and 2026. While the world is focused on B2C chatbots, Carlos explains why the real value lies in Agentic AI systems that don't just talk, but actually execute B2B workflows. We explore the "Year of Evals," where the industry is finally grappling with the struggle of probabilistic vs. deterministic logic, and how to secure these systems from the ground up rather than as an afterthought. Carlos also reveals his exact framework for identifying AI ROI, sharing a case study of a customer who narrowed 412 potential use cases down to just 5 proven implementations. // Carlos Pereira’s SOCIAL // LinkedIn: / capereir /// David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

In this interview, Rob from ThreatLocker breaks down the dangerous reality of password reuse, SIM swapping, and why traditional SMS MFA is no longer bulletproof. We dive deep into how threat actors use reverse proxies like Evilginx to steal session cookies, allowing them to bypass multi-factor authentication and hijack your accounts without ever needing your password. Discover why relying on legacy VPNs and leaving firewall ports open to the internet massively increases your attack surface, leaving your organization just one brute-force attack away from ransomware. Finally, we explore the mechanics of ThreatLocker’s Zero Trust Network Access and Cloud Access, detailing how denying by default and routing through secure proxies can lock down Microsoft 365 and make your internal network effectively invisible to hackers. // Rob Allen’s SOCIAL // LinkedIn: / threatlockerrob X: https://x.com/threatlockerrob // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

Thank you to Cisco for sponsoring this video and sponsoring my trip to Cisco Live Amsterdam 2026. In this interview, Cisco VP Rick Miles breaks down the evolution of the firewall, the massive hardware leap of the 6100 series, and how AI agents and eBPF are completely reshaping the industry. Whether you're trying to secure AI models against prompt injection or wondering if AI will replace your networking job by 2030, this is the technical reality check every engineer needs to hear right now. Has the role of the traditional firewall changed? Rick Miles, VP of Product at Cisco, joins David Bombal at Cisco Live EMEA to reveal the massive architectural shift from static "firewalls" to dynamic "firewalling." This deep-dive interview covers the incredible specs of the new Cisco Secure Firewall 6100 series—boasting 80% less space, 60% less power, and up to 8 Terabits of clustered throughput in a 2RU form factor. We also explore how eBPF is revolutionizing deep visibility and virtual patching directly at the application layer, moving security beyond the edge. But hardware is only half the story. We also break down the new "Wild West" of AI cybersecurity. Learn how to secure the network against prompt injection, poisoned AI models, and unsecured Model Context Protocols (MCP). Finally, Rick shares his vision for 2030: "Agentic" security. Will AI agents replace network engineers, or will they become the ultimate force multiplier for your career? // Rick Miles’ SOCIAL // LinkedIn: / rcmiles09 // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...
