Virtual Patching

Enable compensating controls for legacy OT

Activate the FortiGuard OT Security Service on a FortiGate NGFW and protect vulnerable legacy OT devices with automated virtual patching and custom OT IPS signatures. These compensating controls shield unpatched systems from malicious exploits. As a result, organizations maintain secure, resilient operations as industrial networks evolve and connect to IT, the cloud, and external networks.

Microsegmentation

Get granular security for each switch port

Gain precise segmentation and microsegmentation, reduce lateral threat movement, and maintain secure, resilient industrial networks. With FortiLink tecnnology, your FortiSwitches can be directly managed and secured by a FortiGate NGFW, enabling you to enforce security policies at the individual switch-port level, controlling access for every OT device.

Secure remote access

Secure remote access to OT systems

Protect critical OT systems by granting necessary access with granular controls, monitoring, and auditing. These compensating controls minimize risk and ensure secure, resilient operations. With FortiPAM, organizations can safely manage third-party remote access to OT environments, including internal remote users, contractors, auditors, and vendors.

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.
