Complete, Automated Visibility Across Every Layer of Your OT Environment — Analog, Fieldbus, Serial, and IP
IP-based discovery tools enumerate what is on the network. They cannot see the RTUs, PLCs, protective relays, sensors, and actuators that operate your pumps, breakers, and valves over serial and analog links. The AnalytICS Engine discovers them all, passively, and puts them in one inventory.
Watch: Full-Spectrum OT Asset Discovery & Visibility in Action
See how the AnalytICS Engine bridges the visibility gap between enterprise IP networks and physical Level 1 and Level 0 assets—automatically mapping serial, fieldbus, and analog loops without disrupting operations.
The Problem
Critical infrastructure relies on legacy serial, analog, and fieldbus equipment (RS-232, RS-485, current loops) to control physical processes like pumps, breakers, and valves. Because these Purdue Level 0 and 1 devices were never designed for IP networks, standard discovery tools cannot detect them. This leaves operators with an incomplete inventory, forcing teams to make risk decisions, compliance filings, and incident response plans on a partial operational picture.
The Solution
Cynalytica’s AnalytICS Engine Asset Discovery tool closes that visibility divide with passive, protocol-native discovery across the full spectrum of ICS/OT communications:
- Analog & Fieldbus — Identifies field instrumentation and control equipment communicating over current loop (4–20mA), voltage-based analog signals, and fieldbus protocols at Level 0 of the Purdue Model
- Serial — Discovers and profiles devices communicating over RS-232, RS-485, and RS-422 links, extracting protocol-specific detail from Modbus RTU, DNP3 serial, and proprietary vendor protocols
- IP — Correlates findings with IP-based industrial network traffic, feeding normalized asset and communications data into a single shared visibility layer
AnalytICS Engine applies behavioral analytics and anomaly detection across these non-IP data streams, generating a unified asset inventory and communications baseline that spans Level 0 through Level 3 of the Purdue Model. Discovery is entirely passive and out-of-band, there is no active polling of field devices, no changes to existing control system configurations, and no new network paths introduced into the operational environment, preserving the fail-safe posture that water and electric utility environments require.
The Benefit
- One Complete Asset Inventory — Analog, serial, and IP assets in a single inventory, with the same detail on every device: what it is, how it communicates, and what it talks to, regardless of how it connects
- Visibility Down to Level 0/1 — Extends discovery to RTUs, PLCs, IEDs, sensors, and actuators that conventional IP-based tools were never built to see
- Zero Operational Risk — Passive, non-intrusive monitoring introduces no latency, polling, or risk to live control processes
- Stronger Compliance Posture — Supports documentation and reporting aligned with NERC CIP, AWWA, and other sector-specific regulatory frameworks by evidencing visibility across the full operational technology stack
- A Foundation for Full-Spectrum Security — Establishes the asset and communications baseline that powers correlated threat detection across your entire environment, including as part of Cynalytica’s integration with the Dragos platform for unified IP and non-IP threat detection
