Next-Generation Monitoring Platform and Advanced Analytics for OT Communications – IP, Serial Communications, and Analog Signals
OTNetGuard® is Cynalytica’s next-generation passive and fail-safe network tap that provides secure, out-of-band monitoring for Industrial Control Systems (ICS).
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 backhaul options such as SFP and Wi-Fi or Cellular
✅vIncreased storage capacity and CPU speed allow for edge analytics to reduce bandwidth and local capture storage for offline monitoring

Physical Layer Modules
OTNetGuard’s modular data capture platform allows for the interchange of physical layer modules that give the device the flexibility to capture a wide range of communications common in ICS/SCADA environments.
Modules include the following:
- RS-232
- RS-485/422
- High speed Profibus-DP
- 4-20mA/HART
- 0-10Vdc
- CANbus
- ControlNet
- MIL-STD 1553
- Foundation Fieldbus H1
- Standard Ethernet (100Mbps)
- Modified Ethernet (100Mbps)
Note: Protocol-specific DPI is performed by Cynalytica’s AnalytICS Engine.
