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 your 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 — you gain modern security while keeping operations running smoothly.
Accelerating Industrial Security
Trout solution provides a simple, plug-in solution to Leapfrog sites to a Dynamic Security Maturity.
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.

FAQ
Trout - Secure Existing Networks Without Rebuilding Them
In Summary - Secure Operational Networks Without Rebuilding Them
Trout Software builds plug-and-play network & cybersecurity appliances that create secure overlays for industrial and manufacturing networks — enabling compliance (CMMC, ISO, IEC, NIS2), Zero-Trust segmentation, and secure remote access without rewiring or downtime.
Designed for factories, critical infrastructure, and defense contractors, Trout’s on-premise device discovers assets, segments traffic into micro-DMZ enclaves, enforces identity-based access via Microsoft 365 / Azure AD + MFA, and logs all activity for audit and incident response.
Unlike traditional firewalls or NAC systems, Trout protects legacy and unpatchable equipment through network-level encryption, policy enforcement, and continuous monitoring — bridging the gap between IT and OT security.
By combining agentless deployment, software defined networking capabilities, and real-time visibility, Trout delivers an immediate compliance uplift for organizations seeking to secure operational environments and protect sensitive information.
