The SerialGuard® sensor lets you monitor your most critical legacy assets at the lowest level for superior data integrity and visibility

Designed for Industrial Control Systems, SerialGuard® is a high-performance, fully passive, serial packet sniffer that enables secure visibility within vulnerable legacy networks. The fail-safe sensor passively monitors Level 0 and Level 1 serial communications between field devices and controllers and with the Cynalytica AnalytICS Engine Platform can reveal and help alert traffic anomalies that are indicative of a cyber-attack, physical-attack, or system misconfiguration.

The SerialGuard sensor:

  • Collects serial communications data completely passively – physically unable to write to line
  • Maintains serial communications in event of loss of power to sensor – Fail-Safe Operation
  • Supports Protocol Agnostic RS-232 and RS-485/422
  • Sends Encrypted Data to AnalytICS Engine

Enables ICS Operators to Detect Modern Cyberattack Techniques

SerialGuard® installs in-line between field devices and controllers, enabling ICS operators to detect modern and commonly employed cyberattack techniques:

  • Man-in-the-Middle Attacks: Captures interceptions and alterations of serial communications between field devices and controllers which go otherwise undetected
  • Unauthorized Commands: Captures messages that instruct field devices to perform outside their expected functionality
  • Reconnaissance: Enables operators to detect suspicious probes through the captured data packages
  • Insider Threats: Captures all communications between field devices and controllers, enabling operators to detect unauthorized commands by malicious insiders

Industry Integrations

SerialGuard® can be deployed across all industry verticals that utilize legacy field devices, including many critical infrastructure sectors listed by the US Department of Homeland Security. Typical industry integrations include:

  • Electrical power generation, distribution, and transmission facilities
  • Refineries and other oil-and-gas production facilities
  • Water infrastructure and gas transmission infrastructure
  • Maritime Transportation Systems (MTS)
  • Nuclear reactors, materials, and waste sectors
  • Railway and mass rapid transit systems
  • Chemical production plants
  • Industrial and manufacturing plants
