Trout Access Gate vs. Nozomi
From months-long projects to same-day deployment: The overlay networking advantage
While Nozomi turns OT security into a major infrastructure project with taps, spans, and specialists, overlay networking delivers the same protection through a single appliance that just works — no infrastructure surgery required.
Side-by-side Compare
Plug-and-protect vs. plan-and-pray deployment
Overlay networking eliminates the guesswork — one connection point discovers and protects your entire OT environment through software intelligence rather than hardware placement.
Trout
Single network connection with automatic discovery
Standard network port connection
Same-day operational capability
Built-in zero-trust remote access
Simple, modern UI built for factory teams
Enclave-based access control: device, user, behavior-aware
Flat, predictable pricing
Fast support from engineers who built it
Nozomi
Requires network redesign, VLAN config, and often downtime
Multiple tap points requiring infrastructure planning
Multi-week infrastructure projects
Coverage dependent on tap placement strategy
Additional hardware and infrastructure for expansion
Requires Network engineering and OT security specialization
Choose Trout Access Gate if...
You need OT security that doesn't require OT security experts.
You want complete coverage without playing "guess the optimal tap placement".
You prefer software intelligence over hardware complexity.
You need to scale security as fast as you scale operations.

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.
