Why OT Security Needs to Change

As more assets connect to OT networks, the attack surface grows. Legacy systems weren’t designed to be connected—or defended. Fortinet helps teams protect what matters with visibility, segmentation, secured access, and automated threat response.

Illustration of Fortinet recognition for OT security

A 3x Leader in OT Security

Westlands Advisory named Fortinet the overall leader for the third time in a row in their IT/OT Network Protection Platform Navigator 2025, ranked highest for Strategic Direction and Capability. Fortinet is the only vendor to have been ranked as a leader in every report since inception. Only Fortinet offers a single solution across IT and OT to better help reduce cyber risk across the entire organization, whether threats target the branch office, remote worker, or industrial/OT site.

Real Solutions for OT Challenges

Whether you run air‑gapped PLCs or enable vendor maintenance, Fortinet OT solutions—deployed by AVFirewalls.com—help reduce risk without re‑architecting your plant.

OT Security FAQs

Protocol-aware inspection, OT-specific IPS (FortiGuard), and network segmentation with FortiGate + FortiSwitch reduce blast radius while maintaining availability.

Yes. Virtual patching with OT IPS and microsegmentation using FortiSwitch can mitigate exploits while systems remain in service.

Use approval workflows and session recording in FortiSRA, plus credential rotation with FortiPAM, to control and audit vendor activity.

Operational Technology (OT) refers to the hardware and software used to monitor and control physical processes, devices, and infrastructure such as manufacturing equipment, utilities, and transportation systems. Examples include control systems in factories, pipelines, and power grids.

Industrial Control Systems (ICS) are integrated systems that manage industrial processes. A key subset is SCADA (Supervisory Control and Data Acquisition), which gathers data from remote sensors and transmits it to central control systems for monitoring and automation.

Information Technology (IT) manages data and systems, focusing on confidentiality, integrity, and availability. Operational Technology (OT) manages physical operations — such as controlling machines or critical infrastructure — where safety and uptime are paramount.

OT environments control critical services like energy, water, and transportation. With IT-OT convergence and remote access becoming common, these networks face increased exposure to cyber threats that can cause physical damage or operational disruption.

IT-OT convergence refers to connecting IT systems (data and business networks) with OT systems (industrial control systems). This enables greater visibility and efficiency but also introduces cybersecurity risks that require integrated protection across both domains.
