Are traditional firewalls dead?

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...
