The internet, virtualisation, cloud, SaaS. AI is the next shift, and the old model isn't keeping up. Welcome to Razorwire, the podcast where we share our take on the world of cybersecurity with direct, practical advice for professionals and business owners alike. I'm Jim and in this episode, I'm joined once again by Martin Voelk, co-founder of SpartanX and an ethical hacker with nearly 26 years in cybersecurity. Every major technology shift has forced security teams to rethink how they protect their organisations. The internet moved data outside the building. Virtualisation and cloud meant infrastructure was no longer yours to control. Each time, defence in depth had to evolve. AI is the latest shift, and it may be the one that breaks the model entirely. We trace the journey from on-prem data centres and ISDN routers through to a world where AI agents act autonomously, supply chains are built on unverified code and the offensive side of AI is outpacing the defensive side at a rate security teams can't match. They get into why every AI agent needs its own identity, why shadow AI is a problem most organisations haven't begun to address and why the only realistic answer to AI-powered attacks is AI-powered defence. Three key talking points: Defence in depth has always evolved, but this time it's different: Every previous technology shift gave security teams time to catch up. AI isn't offering that. The pace of change is faster than most organisations can respond to, and the defensive tooling hasn't kept pace with what the offensive side can already do. AI agents need to be treated like people: Every AI agent needs its own identity, authentication and authorisation policies. Without that, a compro…","meta_description":"Defence in depth has evolved every time the technology landscape has shifted. The internet, virtualisation, cloud, SaaS.
