OT Malware

Protection

One infected USB drive. One spear-phishing email. That’s all it took for Stuxnet to cross the air gap. CyInfra deploys ICS-purpose-built endpoint protection that shields your PLCs, HMIs, and workstations without interrupting a single process cycle.
Why it matters

Traditional Antivirus Was Never Built for OT

Conventional antivirus software runs continuous signature update cycles and resource-intensive file scans that interfere with real-time industrial processes. In an OT environment, a brief performance disruption can mean unplanned downtime, production loss, or a safety incident. Standard IT endpoint tools simply cannot operate safely in this environment.

Most OT environments contain a mix of modern and legacy endpoints—Windows XP machines running SCADA software, PLCs with decade-old firmware, and HMIs that have never been patched. These assets have no native protection and cannot run standard security agents. They are open doors into your critical infrastructure.

Ransomware groups have learned that encrypting OT systems creates far greater pressure on operators than encrypting office data. Attacks on industrial endpoints have accelerated dramatically, and without purpose-built protection, facilities remain dangerously exposed to malware that IT security tools won’t even recognize.

Capabilities

What ICS Malware Protection should do

ICS Purpose-Built Anti-Malware

Deploy endpoint protection specifically designed for OT environments—lightweight agents that run on legacy operating systems, use minimal processing resources, and never interfere with real-time control system operations.

Application Whitelisting

Lock down OT workstations and servers to only run approved, trusted applications. Any unauthorized executable—regardless of whether it matches a known malware signature—is automatically blocked before it can execute

Removable Media Control

Enforce strict USB and removable media policies across all OT endpoints. Scan and validate any media before it interacts with your network, closing the primary infection vector used in the most damaging OT attacks.

Endpoint Defense for Industrial Environments

OT Malware Protection Features That Work Without Disruption

Legacy System Support

Protect endpoints running Windows XP, Windows 7, and other end-of-life operating systems that are common across industrial environments and ineligible for standard security updates.

Real-Time Protection with Zero Operational Impact

Detect and block malware in real-time using signature-based and behavioral analysis engines sized for industrial hardware—no scan windows, no performance degradation, no process interference.

Behavioral & Heuristic Analysis

Identify and stop zero-day threats and novel malware variants that have no known signature, using behavioral pattern analysis tuned to the specific application landscape of industrial control systems.

Centralized OT Endpoint Management

Manage policies, monitor health, and respond to incidents across all OT endpoints from a single console—with full audit trails to support compliance with ISA/IEC 62443 and NERC CIP requirements.

Common questions

Frequently asked questions

What is an OT firewall?
OT (Operational Technology) firewall is a network security device designed specifically for industrial control systems (ICS) and operational technology (OT) networks. Unlike a traditional IT firewall, an OT firewall is designed to protect critical infrastructure from threats that are specific to industrial environments, such as cyber-physical attacks and industrial espionage. IT and OT firewalls are very similar in functionality, often made by the same manufacturer like Fortinet, Checkpoint, however there are still some differences between enterprise firewalls and industrial firewalls, mainly in the form factor.
