OT/ICS Security
Stop attackers from turning operational systems
into operational shutdowns.
The Challenge
Attackers are exploiting visibility gaps between IT and OT environments before security teams can respond.
Operational Technology (OT) and Industrial Control Systems (ICS) environments were traditionally isolated from external networks. Today, increasing connectivity between IT and OT systems, remote access requirements, cloud integration, and industrial IoT adoption have significantly expanded the attack surface. As a result, OT/ICS security has become a major concern for organizations operating manufacturing plants, utilities, energy systems, transportation networks, and critical infrastructure.
Unlike traditional IT environments, OT and ICS systems often run legacy technologies that cannot be patched easily or taken offline without disrupting operations. Security teams frequently struggle with limited visibility into industrial protocols, unmanaged assets, and east-west traffic moving across operational networks. Attackers exploit these blind spots to move laterally, disrupt production, deploy ransomware, or target physical processes directly.
Without strong OT ICS security monitoring and detection capabilities, organizations may not identify malicious activity until operational downtime, safety incidents, or infrastructure disruption have already occurred.
Our solution
Detect threats across industrial networks earlier and respond before operational disruption spreads.
Fidelis Elevate® helps organizations improve OT ICS security by combining network detection, threat intelligence, endpoint visibility, and deception-driven detection into a unified platform. Fidelis provides deep visibility into network traffic and attacker behavior, helping security teams detect suspicious activity across IT and OT environments before attacks escalate.
- Deep Network Visibility: Fidelis Network® provides inspection across ports, protocols, and encrypted traffic to identify suspicious activity inside operational environments.
- Detection of East-West Movement: Network analytics help detect internal reconnaissance, unauthorized lateral movement, and abnormal communication patterns across OT environments.
- Integrated Threat Detection and Response: Fidelis Elevate® correlates network, endpoint, and threat intelligence signals to improve investigation and accelerate response.
- Deception-Based Threat Detection: Fidelis Deception® deploys decoys and deceptive assets that help expose attackers attempting to move inside operational networks.
- Reduced Operational Blind Spots: Continuous visibility across hybrid IT and OT environments helps security teams identify unmanaged assets and suspicious behavior earlier.
Why Now?
OT and ICS environments are becoming primary targets for operational disruption and ransomware attacks.
1,466
documented ransomware incidents hit the manufacturing sector in 2025, representing a 56% surge that now accounts for half of all global ransomware attacks.
150%
surge in maritime OT cyber incidents throughout 2025 highlights how critical transportation infrastructure has become a primary target for disruptive ransomware campaigns.
49%
year-over-year increase in ransomware groups targeting industrial organizations has expanded the threat landscape to over 3,300 impacted entities globally by early 2026.
