Cybersecurity Leadership. AI Infrastructure. Built from Scratch.
I’m Ron Craighead — CISSP, AIGP, and cybersecurity infrastructure leader with 20+ years securing enterprise environments from startups to Fortune 500 to NASDAQ IPO. I build the systems that keep organizations compliant, monitored, and defended.
This site is a living portfolio: a fully operational enterprise lab — Active Directory, PKI, SIEM, network monitoring, AI inference — built on commodity hardware and documented end to end.
CyberLab — Enterprise Infrastructure, Home Scale
A 3-node Proxmox cluster running Active Directory, network monitoring, log management, AI inference, and security testing. Total hardware cost: under $1,500. Software cost: $0. Every component documented.
- Lab Overview — hardware, architecture, and why you should build one
- Infrastructure Walkthroughs — network segmentation, Proxmox clustering, AD/DNS/DHCP, monitoring stack
- Live Projects — PKI, endpoint management, smart home automation, penetration testing
AI & GPU Infrastructure
GPU-accelerated AI inference on an RTX 4070 running Ollama with Qwen3 models (8B–32B parameters). From GPU passthrough in Proxmox to TensorRT-powered object detection — real AI/ML infrastructure, not cloud APIs.
Aviation — The Other Passion
Instrument-rated commercial pilot and independent CFI in San Diego. I teach people to fly using the same philosophy I bring to IT: learn on the ground before the stakes are high. Simulation-integrated training, structured curriculum, and a 53-hour sim program that saves students 20+ flight hours.
