The End of Legacy Network Security

The End of Legacy Network Security, by Todd Ellison, argues for replacing layered, box‑centric designs with outcome‑driven networks where security is native. It champions “security built‑in, not bolted on” via native Zero Trust at the access layer, per‑device isolation to stop lateral movement, and an integrated, cloud‑driven architecture that operates at “cloud speed,” replacing brittle VLAN/ACL/NAC stacks with an identity‑aware fabric that’s continuously current, observable, and assured.

Field Chief Technology Officer, Nile

Todd Ellison is Director of Solutions Architecture at Nile, where he helps enterprise organizations rethink how networks are built, secured, and operated. With deep technical expertise and a knack for making complex concepts accessible, Todd bridges the gap between architecture and real-world outcomes for the customers and audiences he engages. A passionate advocate for moving beyond legacy, box-centric infrastructure, Todd's work centers on the belief that security must be built in — not bolted on. He champions identity-aware, cloud-driven architectures that deliver Zero Trust natively at the access layer, where continuous observability and cloud-speed operations replace the complexity of yesterday's security perimeter.
