Isecure,route,andreason.
I secure, route, and reason about networks - equal parts red team and blue team, with a generalist's habit of following a packet wherever it goes.

About
A quiet practice in networks
Cybersecurity Engineer & Network Generalist
My work lives across the whole network stack: offensive testing, defensive engineering, and the routing that quietly holds it together.
I operate my own autonomous system, AS133555, announcing address space and peering at internet exchanges. Running real infrastructure keeps the theory honest.
