IT and OT cybersecurity protect two fundamentally different worlds, with distinct objectives and constraints. Here are the core differences:

Criteria IT Cybersecurity OT Cybersecurity
Priority Data confidentiality, availability, integrity, and auditability Availability, operational safety, and operational continuity
Environment Servers, workstations, on-premise or cloud applications SCADA, PLCs, sensors, actuators
Lifecycle 3–5 years, regular updates 15–30 years, unpatachable legacy systems
Fault Tolerance.  Restarts are acceptable Zero interruption—physical safety at stake
Expertise IT teams, traditional SOCs Automation engineers, process engineers, OT specialists
   

 

Why This Distinction Is Critical? Applying IT security tools to OT can cause production shutdowns, generate massive false positives (53% of OT alerts), and remain incomprehensible to field teams. An IT firewall can block a critical command to a PLC. An active network scan can crash a 20-year-old controller.

The IT/OT convergence demands a new approach: solutions engineered natively for OT, non-intrusive, that speak the language of automation engineers and respect 24/7 availability constraints.
