We ran OT security by hand for ten years. So we built Resilion.

Hillstrong spent a decade running OT security programs inside Fortune 500 manufacturers, utilities, and critical infrastructure operators. We wrote the charters, scored the maturity, ran the assessments, and assembled the audit evidence by hand, site by site. Resilion is that work, encoded so it scales.

The consulting team is still here. When you need people on the ground to stand up the program, we run implementation and onboarding alongside the platform.
