Why Trout?
Industrial Cybersecurity, Without Downtime
Industrial networks are more connected than ever — and more exposed.
Legacy systems, IT, and OT now share the same risk surface. But rebuilding OT networks isn’t an option: it’s slow, costly, and would bring operations offline for days or weeks. Air-gaps don’t fit digital transformation, and compliance demands are only growing.
Trout solves this with a Secure Twin overlay — modern security, without disruption.
Accelerating Industrial Security
Trout Technology
Trout is a plug-in solution that gives visibility, access control, and protection, without disruption.
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.
Visibility. Maps who talks to who across assets, behaviors, and protocols
Segment & Control. Define zones to isolate systems and enforce least-privilege access
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.
