Shadow AI: What every network engineer must know

David Bombal interviews Radware North America lead Randy Wood on what AI is actually doing inside enterprises, framed as a 1994 internet moment times a thousand. Wood walks through the five concerns customers voice every week, data, identity, visibility, the threat landscape, and the loss of autonomy, and explains why shadow AI is the new shadow IT. He argues guardrails fail against autonomous agents and Radware instead validates behavioral intent before execution, then ranks DDoS, API, and bot attacks as the top vectors and calls API security a board mandate, since firms that think they run a thousand APIs often have fifteen thousand. He closes with three predictions and advice to young people to make peace with AI without outsourcing their thinking.

My Dream "home lab"

David Bombal tours Cisco's 20 million dollar AI networking lab to answer the question most AI coverage skips: once you have the GPUs, how do you wire hundreds of thousands of them into one computer. Three Cisco engineers walk through scale up, scale out, and scale across, the new G300 100 terabit and P200 routing switches, why optics are often the most expensive line on the bill, and how a 128 GPU scalable unit plus simulated flows proves designs at much larger scale. The recurring lesson is economic: a 10,000 GPU cluster rents for 175 million dollars a year, so a 5% efficiency loss or one bad cable costs millions. It also settles the InfiniBand versus Ethernet debate (Ethernet wins at scale) and shows security moving off the edge firewall and into the fabric on DPUs and switches.

Vibe Hacking: How AI Is Helping Hackers

David Bombal interviews Radware threat researcher Pascal Geenens about the 2026 Global Threat Analysis Report and the argument that novice hackers now wield power once reserved for nation states. The conversation maps four fronts: vibe hacking, where AI acts as a patient tutor and an agentic attack engine with platforms like Xanthorox AI; a DDoS escalation with volumetric attacks up 168 percent and record 30 terabit per second demonstrations; an API and bot front where legacy APIs and account takeover get industrialized by AI voice agents; and the new attack surface AI itself opens. The AI native section covers indirect prompt injection plus Radware's Shadow Leak and Zombie Agent research against ChatGPT, why guardrails are patches not cures, and MCP tool description poisoning. It is authorized security education, and the throughline is that awareness and visibility are the first real defense.

Firewall Demo of Red Team vs Blue Team: Hacking Finance Apps with AI Chatbots

David Bombal and a Cisco network security engineer walk through a full red team versus blue team demo on a fictional finance app that has quietly grown a GPT 3.5 Turbo chatbot. The attack story runs end to end: AI Defense red teams the chatbot and finds prompt injection holes, the blue team converts those findings into guardrails, Secure Workload maps the Kubernetes environment and surfaces a rogue Apache test pod, plaintext HTTP between tiers, and an exploitable CVE, and Secure Firewall catches users SSHing into the front end and a zero day hidden in encrypted traffic. The defenses are tied together by the hybrid mesh firewall idea: enforcement embedded everywhere across the fabric rather than one box at the edge. It is authorized security education built on the guest's own lab.
