About us
Resilium was founded in Ireland in 2025 by industry professionals who have spent their careers working inside live operational environments, not just securing them from the outside. The company was created to address a critical gap in cybersecurity: the protection of Operational Technology (OT) systems that control physical processes where safety, uptime, and reliability matter most.
Resilium is led by co-founders with decades of hands-on experience across pharmaceutical manufacturing, energy, and industrial technology environments, having worked directly in operational, engineering, and automation roles. This operational background shapes everything we do, delivering practical, safety-first OT cybersecurity designed to work in the real world, not just on paper. Our vision is to raise the standard of OT cybersecurity by delivering protection that operators can trust, rely on, and safely run every day.
Resilium is a managed cybersecurity service provider (MSSP) dedicated to protecting Operational Technology (OT), the industrial systems, networks, and physical equipment that run industrial operations. We focus on securing what traditional IT security is not designed to protect: manufacturing control systems, utilities, building management systems, industrial networks, and other operational infrastructure where safety and uptime are critical.
We remove the operational burden of OT cybersecurity for operations teams, addressing challenges such as limited engineering capacity, specialist knowledge gaps, and the need for a sustainable long-term model. We do this by deploying, integrating, and fully managing security solutions on your behalf, delivering continuous, managed protection without diverting resources from core operational responsibilities.
Cyber risks in OT environments don’t just threaten data, they can halt production, damage equipment, create real-world safety hazards, and impact your ability to deliver products or services.
Traditional IT security isn’t designed to protect the operational systems, physical equipment, and industrial processes that run your business. Without specialised OT security, gaps remain in visibility, threat detection, and response, leaving critical operations exposed.
Protecting OT is essential to maintaining operational continuity. In environments where uptime and safety are critical, specialised OT cybersecurity isn’t optional, it’s essential for protecting the people, equipment, and processes your business depends on.
We take a structured, end-to-end approach to protecting operational technology. We start by understanding your environment, identifying vulnerabilities, and establishing a strong foundation of protection. From there, we continuously monitor your systems, detect threats in real time, and respond with context-aware, expert-led action.
We deliver this through a layered approach, using best-in-class security solutions from our trusted technology partners. We deploy, integrate, and manage these platforms on your behalf, providing continuous, hands-on protection tailored to your operational needs. By combining industrial engineering expertise with advanced partner platforms, Resilium ensures your operational equipment stays safe, reliable, and resilient without adding burden to your team.
