Network Security Monitoring

Effective OT security needs comprehensive data. Dragos captures more industrial network data than any solution using passive-first, ICS-aware methods—without disruption.

Why OT Network Security Monitoring & Logging Matters in OT Environments
Legacy devices with limited telemetry, proprietary ICS protocols, and segmented architectures make OT visibility challenging. Dragos delivers ICS network monitoring with safe collection and deep packet inspection so teams can keep operations resilient and monitor where adversaries may hide.
Turn Network Data into Security Outcomes

Dragos turns raw OT traffic into usable insight. Detect threats sooner, validate communications, troubleshoot faster, and support compliance requirements like NERC CIP-015—all while strengthening day-to-day reliability.

Discover Assets and Vulnerabilities
Monitoring builds a dynamic asset inventory, surfacing devices and communication paths while providing the context to identify potential vulnerabilities and exposures.
Detect Threats Earlier and with Confidence
ICS-aware analytics and high-fidelity detections reduce noise and surface behaviors that matter, helping teams act before issues escalate.
Validate Communications and Segmentation
Network monitoring with firewall and configuration analysis validates segmentation by checking flows against intended zones and surfacing gaps that could allow lateral movement.
Faster Investagtions
Detailed network visibility, timelines, the ability to query historical data, and case workflows speed triage and reduce mean time to resolution.
Network Security Monitoring in Action
In OT networks, even subtle changes in expected behavior can signal big risks. For example, a vendor workstation issues OT commands outside a maintenance window. Because of network security monitoring, analysts are able to identify the unusual activity with OT-specific intelligence, helping analysts separate real threats from routine noise and act quickly.
What Our Customers Are Saying
  • What’s been helpful with Dragos is not just the technology, but the expertise that they bring to the table. Koch can now identify ICS/OT threats, rapidly pinpoint malicious behavior on their ICS/OT networks, provide an in-depth context of alerts, and reduce false positive alerts for complete threat detection.
    Gabe Green, CISO Koch Industries
  • We were initially focused on anomaly detection software and originally thought that we would benefit from the ability to see and react to alerts. But we quickly realized that the majority of those solutions just weren’t as mature as we needed. This awareness led us to consider OT visibility platforms in general, and the conversation pretty much started and stopped with Dragos.
    CISO, Electric and Water Utility
  • With the visibility provided by the Dragos Platform, automated monitoring capabilities alert the security team to potentially malicious behavior between assets and communications, so they can rapidly investigate and respond before attackers can progress.

Common questions about protecting food production operations from cyber threats and implementing effective OT security programs.

OT monitoring must avoid disruption. Dragos uses passive network monitoring sensors and ICS-aware DPI to deliver visibility safely.

Dragos inspects 600+ industrial and IT protocols at multiple layers, with deep focus on Layer 7 to provide command-level context for OT communications.

Dragos provides the collection, layered detection, evaluation, and retention capabilities needed for internal network security monitoring (INSM) by monitoring internal traffic and preserving evidence.

Yes, when executed correctly. Active Collection with the Dragos Agent is purpose-built for OT and optional. Deployed on Windows-based devices, it performs controlled queries to gather OS, firmware, patch, and module data. It complements passive monitoring and is strategically deployed to minimize operational risk.

Network monitoring helps teams quickly spot misconfigurations, troubleshoot issues and improve overall reliability by providing clear operational context from traffic data.
