Why OT security matters
Industrial operations are different from typical IT environments. They need to stay running, keep people safe, and operate securely, which means traditional security approaches often miss critical vulnerabilities. As OT and IT systems connect more closely, new risks emerge through legacy systems, remote access, and network gaps.
You need security designed specifically for how industrial operations work. OT Security Services delivers that expertise. Security built around your environment so you operate safely, reliably, and with confidence as threats continue to evolve.

Operational Technology FAQs
What is operational technology (OT) security?
OT security involves protecting industrial systems such as SCADA, PLCs, and ICS environments from cyber threats. These systems control physical processes in sectors like manufacturing, utilities, energy, and transportation.
Why is OT security different from IT security?
OT systems were traditionally isolated and designed for safety and availability, not cyber resilience. They often run legacy technologies, have limited patching options, and require specialized approaches to avoid operational disruption.
What challenges do organizations face with OT security?
Key challenges include:
-
Legacy systems with poor security controls
-
Limited visibility into OT assets
-
Converged IT/OT environments
-
Supply chain risks
-
Inability to apply traditional security tools
-
Meeting compliance with NIS2, ISA/IEC 62443, and OSFI B-13
