Why Trout?

Industrial Networks Need Purpose-Built Security

Industrial networks have grown connected and complex. The reality of these environments:

  • Legacy Infrastructure: many older devices can’t run modern security agents.

  • Protocol Complexity: standard enterprise NAC solutions struggle with industrial protocols.

  • Operational Requirements: Security deployments must not disrupt production, making high-touch solutions unsuitable for industrial environments.

Trout Technology

Trout creates an intelligent security layer that works with your existing network topology

Trout is a drop-in appliance for OT networks — built to give IT teams visibility and control without the usual overhead. No more SSH’ing into devices to tcpdump, managing a fleet of agents, or fielding endless VLAN access requests.


Everything you need in one appliance

Plug & See. Connect Trout to your firewall or switch — see assets and protocol flows. No additional rewiring needed or VLAN work.

Segment & Control. Define software-enforced zones to isolate systems and enforce least-privilege access across your network.

Secure Remote Access. Grant on-demand, policy-driven access for contractors or remote teams — with visibility and control.

Log & Prove. Capture clean, structured logs from the edge. Feed them into your SIEM or use them for root-cause and audit trails.

Automate Compliance. Enforce security policies and automate audit-ready evidence.
