Built for Industrial Control Systems, SerialGuard® Delivers Unmatched Visibility into Legacy Serial Communications
SerialGuard® is a high-performance, fully passive and fail-safe sensor designed specifically for Level 0 and Level 1 environments in critical infrastructure. Purpose-built for serial ICS networks, it enables secure, real-time visibility into legacy device communications, without introducing risk or disruption.
Operating as part of the Cynalytica AnalytICS Engine Platform, SerialGuard continuously monitors serial traffic between field devices and controllers. By correlating this data with IP and analog signals, the platform can identify anomalies indicative of cyberattacks, physical tampering, equipment misconfiguration, or operational failures.
Key Capabilities of the SerialGuard Sensor:
- Truly Passive Monitoring – Physically incapable of writing to, or interrupting the communication line
- Fail-Safe Operation – Maintains serial communication even during power loss
- Protocol-Agnostic Support – Compatible with RS-232, RS-485, and RS-422 interfaces
- Secure Data Handling – Encrypted transmission of collected data to the AnalytICS Engine for centralized analysis
SerialGuard is not just another network tap, it is a foundational part of a complete, cyber-physical monitoring platform that gives operators deep, actionable insight into the blind spots of traditional ICS cybersecurity systems.
