OT Malware
Protection
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.
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.
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.
