Safe, Accurate Visibility. Without Risking Operations
Trout Access Gate delivers real-time insight into networks through passive observation. Accurate visibility you can trust from day one.
Passive Network Monitoring
Observe traffic without touching endpoints or disrupting operations.
NetFlow & PCAP Ingestion
Natively ingest existing telemetry from taps, routers, or collectors.
Automatic Discovery
Identify devices, roles, and communication patterns instantly.
Protocol Identification
Decode IT and OT protocols to understand real system behavior.
Flow Direction Mapping
Visualize who talks to whom, including east-west industrial traffic.
WASM Processing Engine
Scalable, edge-native analytics to process data without added infrastructure.
Passive Visibility Is Essential in Critical Environments.
No Disruption
Critical on-premise systems are defined by uptime. They require technology that does not disrupt operations. See how the Access Gate delivers passive visibility without touching your network.

Questions and Answers
Active probes sent to your OT network. The Access Gate operates entirely from passive NetFlow analysis — no scanning, no agents, no disruption.
No. The Access Gate operates passively by analyzing NetFlow data from your existing switches and routers. It never sends probes, installs agents, or generates traffic on your OT network. Deployment is non-intrusive and requires no downtime.
Yes. Because the Access Gate works from network telemetry rather than device interrogation, it identifies any device that communicates on the network — including legacy PLCs, old HMIs, and proprietary industrial equipment that can't run agents or respond to SNMP.
Vulnerability scanners actively probe devices, which can crash sensitive OT equipment and generates significant network noise. The Access Gate takes the opposite approach: it passively observes traffic patterns to build an inventory without ever touching a single device. You get accurate visibility without the risk.
The asset inventory maps directly to NIST 800-171 Configuration Management (CM) controls required for CMMC, NIS2 Article 21 asset identification, and IEC 62443 zone and conduit models. Reports can be exported on demand for auditors.
Yes. The Access Gate provides a REST API for exporting inventory data in JSON or CSV format. You can integrate with ServiceNow, Splunk, QRadar, or any platform that accepts structured asset data.
