Benji Vesterby
Founder & Principal Security Engineer
Automation‑first OT/ICS & detections (Go‑first). Founder of CodePros; specializes in OT DPI, detection engineering, security automation, PDNS, and runtime AppSec.
I fell in love with computers early—building PCs, teaching myself to code, and chasing distributed systems, AI, and security. In 2017 I discovered Go at SANS and joined my first GopherCon a year later. The community’s pragmatism shaped my approach: ship real code, measure outcomes, share what works. Today I help run the GopherCon CTF, training 160+ engineers a year.
Professionally, I’ve spent 18+ years building and securing robust, scalable systems—pioneering security automation, OT/ICS deep packet inspection, and runtime AppSec. My work is measured in deltas: +65% IDPS precision, major FP reduction, and −95% MTTR.
At CodePros, I lead an automation‑first OT/ICS & detections studio (Go‑first). We ship productized offers—OT/ICS DPI Accelerator, IDPS Effectiveness Boost, Security Automation Jumpstart, Protective DNS Assessment / Deployment, and Runtime AppSec Enablement—through Labs→POC→Prod or Build‑Transfer‑Operate. We prove impact with precision/recall, FP rate, Gbps & CPU/GB, MTTR, and POC→Prod conversion.
I also serve as Principal Security Engineer at QuantumScape, focusing on automation, detection engineering, and incident response.
Outside of work: photographer, PADI‑certified SCUBA diver, and relentless bread‑baker chasing the perfect sourdough.
