About

I’m Jared, an OT security practitioner based in Oklahoma.

My path into security went through the field:

Field tech. Installing and supporting machines on site.
SCADA analyst. Six years building HMI graphics, mapping Modbus registers to tags, writing unit conversions and keeping the servers running.
Field communications. Licensed and unlicensed radio, cellular modems, VSAT, point-to-point links and mesh networks for remote sites.
Security. Information security, then OT security engineering, and now OT security leadership.

I also volunteer on industry advisory boards for technical education and speak to students about OT security careers.
