Operational Technology Cybersecurity

Overview

  • Keeps critical infrastructure operational: OT systems control essential services, from energy grids to water treatment. A successful attack can halt operations and put lives at risk.
  • Addresses outdated and vulnerable tech: Many OT environments run on legacy systems not built for today’s threat landscape. Pen testing helps identify security gaps before attackers do.
  • Reduces risk of nation-state or ransomware attacks: In 2022 alone, 24% of ransomware attacks targeted industrial environments, with OT-specific malware on the rise.
  • Supports compliance and resilience: With regulations like NIS2 and IEC 62443 becoming standard, regular testing helps prove compliance and reduce insurance premiums.

Operational Technology Cybersecurity Built for High-Stakes Environments

Operational Technology (OT) systems keep the physical world running, controlling power plants, manufacturing lines, transport systems, and water treatment facilities. But as these environments become increasingly connected, they’re also becoming more exposed.

In fact, a Dragos 2023 Year in Review found that all 22 OT/ICS sectors analysed had at least one active threat group targeting them, with ransomware groups focusing more heavily on industrial control systems than ever before.

At Fortifi, we understand the unique demands of OT. Our CREST-accredited penetration testing isn’t limited to IT systems, we specialise in assessing complex OT networks where uptime, safety, and regulatory compliance are paramount.

The Case for Real OT Security

  • Downtime is dangerous: OT attacks aren’t just about data, they’re about disruption. The Colonial Pipeline attack in 2021 showed how a single breach could cripple fuel supply across the US East Coast, costing an estimated $4.4 million in ransom.
  • Legacy systems are vulnerable: 53% of OT devices are more than 20 years old, making them difficult to patch and easy to exploit (Claroty, 2023).
  • Threats are growing: The number of vulnerabilities reported in ICS systems rose 27% year over year in 2023 (SynSaber, 2024), and many are exploitable remotely.
  • Compliance is tightening: New frameworks like NIS2 and industry standards such as IEC 62443 are pushing organisations to demonstrate robust cyber risk management and testing.

Why OT Teams Choose Fortifi

We help critical infrastructure providers, manufacturers, and industrial firms:
