About Us

Sentinel Dynamics is a Springfield cybersecurity practice specializing in the systems that cannot afford to fail: industrial control systems, building automation, fire alarm and life-safety networks, and the operational technology behind manufacturing lines, water treatment, hospitals, and public facilities.

In these environments, a security breach isn't a help desk ticket. It's a safety event.

Founder Aaron Manuel brings thirty years across manufacturing, healthcare, higher education, state government, and defense. He started troubleshooting circuits as an Army National Guard communications technician and industrial electrician, worked plant engineering at Kettering Medical Center, led facilities operations planning at The Ohio State University, directed test equipment engineering at Honda R&D Americas, and managed capital projects, IT, and OT projects at the Ohio Statehouse from bid through closeout.

The result is a practice run by someone who has held the multimeter, planned the maintenance, managed the project, and run the compliance program.

Services: passive OT and ICS security assessment with no agents, no active scanning, and no downtime; CMMC and NIST SP 800-171 readiness; facility control system cybersecurity for federal and DoD projects.
