Technological progress has accelerated IT and OT environments have evolved just as quickly. Today’s industrial systems are merging with IT to harness data, improve operations, and give organizations a competitive edge. But IT/OT convergence also brings challenges: strict OT regulations, legacy architectures, and cyber risks that threaten not only uptime but also Environmental, Health, and Safety (EHS).

Unlike classic IT, OT environments resemble machine engineering highly specialized, safety-critical, and deeply dependent on availability. Yet they face the same cyberattacks as IT, along with more advanced threats that can disrupt production or even endanger lives. Despite being harder to reach, OT networks remain attractive targets for attackers looking for maximum impact.

At NIL, we provide a comprehensive portfolio of industrial cybersecurity services designed to make your OT environment safer, compliant, and ready for growth. No matter your current maturity level, we support your journey with expertise, structure, and long-term partnership.

The challenge: Why traditional IT security doesn’t work in OT

IT security is built on standardized control, but these often fail in OT or even cause unintended outages. OT security depends on a use-case-driven, industry-specific approach. Standards such as ISA/IEC 62443 or ISO 27000 align with IT only at a high level; in OT, availability is the key principle.

Threats are evolving just as fast. If an OT environment isn’t affected by IT spillover or random attacks, it becomes a target for increasingly sophisticated adversaries who know exactly where industrial organizations are most vulnerable. Cyberattacks remain a major cause of operational disruption and for small companies, more than 60% never fully recover after a serious incident.

In industries driven by productivity, product availability, and tight margins, the risk is extreme.

What makes NIL’s OT Security different?

We embrace complexity together with you

Technical products are not our starting point. We are not here to sell the newest “Product of the Year.” Our focus is people. Our OT specialists bring deep technical expertise, and your teams bring real knowledge of your industrial processes. Together, we build solutions that make sense for your environment.

We take time to understand how your operations work, identify what truly matters, and create an OT security solution shaped by your input. It has to be something we are proud to deliver and something you can trust to support safe and reliable operations.

And when the project ends, our partnership does not. We stay with you as your long-term OT security partner, ready to support new challenges, new risks, and the ongoing evolution of your industrial environment. This is how we create lasting value and strengthen your industrial cybersecurity for the future.

A step-based, trust-driven approach

Strong OT security is a journey. Each milestone builds the foundation for the next, creating long-term relationships that generate multiplied (not just added) value.

You choose how far you want to go. With us, your options include:

  • Asset inventory – Periodic or project-based asset and vulnerability visibility
  • OT cybersecurity assessments – Based on ISA/IEC 62443, ISO 27000, TISAX, and industry frameworks
  • OT security workshops – From cybersecurity blueprinting to supply-chain and procurement policies
  • Technical services – Design, implementation, and optimization across the OT domain
  • Managed OT services – When you’re ready to offload operational burden and scale securely

Why NIL, part of Conscia?

  • 20+ years of industrial cybersecurity expertise
  • Solutions built for critical infrastructure (manufacturing, energy, utilities, transport)
  • Fast, scalable delivery powered by proven SOC practices
  • Higher value, lower overhead than building in-house OT security capabilities
