Rethinking Container Security: Why Isolation Was Never Built In (with Alex Zenla)

In this episode of Nerding Out with Viktor, host Viktor Petersson sits down with Alex Zenla, Founder and CTO of Edera, to unpack why container security has been built on a flawed assumption from the start. The conversation traces Alex's journey from working in deeply insecure IoT and industrial systems to building Edera, a company focused on rethinking isolation at the runtime level. Along the way, they explore how containers became the default abstraction, despite relying on shared kernel state and weak isolation guarantees. The discussion covers the technical trade-offs behind namespaces, virtualization, and hypervisor-based approaches, as well as the real-world challenges of securing modern workloads. As AI agents and autonomous systems push infrastructure in new directions, the limits of today's container security runtime are becoming harder to ignore. This episode offers a grounded look at what needs to change and why a different approach to isolation may be necessary for the next generation of systems.
