The Challenge

OT Blind Spots Can Become Operational Disruptions

Operational technology environments were built for reliability and uptime, not modern cyber threats. As industrial networks become more connected to IT, cloud, remote access, and third-party systems, attackers have more opportunities to move into critical environments.

Security teams struggle with:

  • Limited visibility into OT assets, devices, and industrial communications
  • Legacy systems that cannot support traditional security agents
  • Increasing connectivity between IT and OT networks
  • Difficulty detecting threats across industrial protocols
  • Limited visibility into encrypted or anomalous OT traffic
  • Risk of disrupting operations when investigating or responding to threats
  • Fragmented visibility across IT and OT environments
  • Lack of historical evidence for investigating OT incidents

The Solution

The NetWitness Approach to OT Security

NetWitness’ OT security platform is designed to deliver comprehensive visibility into industrial networks for security and operational teams. NetWitness, powered by DeepInspect, provides passive monitoring, automated asset discovery, OT threat detection, industrial protocol analysis, and network forensics to detect threats without impacting operations.

Deep Visibility Across OT Networks

Gain continuous OT network security visibility into devices, communications, and industrial traffic. NetWitness monitors network activity across production environments and helps security teams identify what is connected, how assets communicate, and where potential risks exist.

Automated OT Asset Discovery

Discover and maintain visibility into OT devices across the environment, including industrial systems and connected assets. Automated asset discovery helps teams identify unmanaged and previously unknown devices that could create security gaps.

OT Threat Detection Designed for Industrial Environments

Use signatures, rules, behavioral analytics, and network-based detection to detect suspicious activity. Only NetWitness analyzes OT traffic to detect and filter abnormal communications, unauthorized activity, potential threats, and supports an OT environment’s operational needs.

Industrial Protocol Visibility

Go deeper into industrial communications with custom protocol dissection and deep packet inspection. Analyze OT-specific traffic and identify unusual communications that conventional IT-focused monitoring may overlook.

Unified IT and OT Security

Attackers do not always enter through the OT network. NetWitness correlates activity across IT and OT environments to expose attack paths that cross the boundary between enterprise and industrial networks.

Deep Forensics for OT Investigations

When an incident occurs, security teams need evidence, not assumptions. NetWitness provides access to rich metadata and raw network data for session analysis, investigation, historical hunting, and forensic reconstruction.

How NetWitness Works

From OT Visibility to Threat Response

Discover

Continuously identify OT assets and map communications across industrial networks.

Monitor

Capture rich network telemetry and analyze industrial traffic without requiring endpoint agents.

Detect

Apply threat detection, behavioral analytics, rules, and protocol-aware analysis to identify suspicious OT activity.

Correlate

Connect OT events with activity across IT networks to uncover attacks that move between enterprise and operational environments.

Investigate

Use metadata, packet-level evidence, session analysis, and historical visibility to understand the scope and impact of an incident.

Respond

Give security and operational teams the evidence and context needed to make informed response decisions without unnecessarily disrupting critical processes.
