Next-Gen Monitoring for Industrial Serial Communications, Analog Signals, and TCP/IP PCAPs for ICS/SCADA and IIOT Environments

OTNetGuard™ is Cynalytica’s next-generation passive and fail-safe network tap that provides secure, out-of-band, monitoring for Industrial Control Systems (ICS). The sensor boasts many new and enhanced features from its predecessor, SerialGuard®.

Features include:

✅vAll new modular data capture platform to support a wide range of OT network communications such as analog signals, serial communications, and TCP/IP network traffic

✅vCompatibility with Cynalytica’s AnalytICS Engine which offers encrypted communication backhaul, deep packet inspection (DPI), in-depth analytics, and alerting of captured signals with integrations for existing SIEM/SOAR solutions

✅vAdditional capture back-haul options such as SFP and Wi-Fi or 4G/5G Cellular

✅vIncreased storage capacity and CPU speed allow for edge analytics to reduce bandwidth and local capture storage for offline monitoring
