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.
