Secure every OT asset. Without touching one.
From PLCs and HMIs to the legacy servers and desktops running your plant, Trout protects the critical systems you can't patch, agent, or replace, with a non-intrusive Zero-Trust overlay.
✓In the cloud, Zero Trust is solved.
×On-premise, the LAN still runs on implicit trust. Low visibility, limited access control, no audit trail.
×But you can't add agents to legacy equipment, and refactoring the network means downtime operations can't take.
Trout closes the gap.
Non-intrusive Zero-Trust overlay on your existing LAN. Asset visibility, access control, microsegmentation, compliance, then the secure services your OT depends on. No agents, no rewiring, no downtime.
In the cloud, Zero Trust is solved. Agents on every workload. Identity verified everywhere.
On-premise, the LAN still runs on implicit trust. Low visibility. No audit trail. Critical assets exposed.
And it's now a footprint to cover: more remote access, IT tying into OT, new compliance mandates, escalating attacks.
But you can't add agents to legacy equipment, and refactoring the network means downtime operations can't take.
Trout closes the gap.
Access Gate plugs into your existing LAN and builds a non-intrusive Zero-Trust overlay.
Asset visibility, identity-based access control, microsegmentation, and compliance from day one. Then it offers secure services your OT can easily consume. Solving a technical challenge today and building a stronger process for tomorrow.
No agents, no rewiring, no downtime.
Appliance On-Site, Running Security Proxies at Scale
Trout Access Gate is a purpose-built appliance that runs industrial proxies at scale, placing a security proxy in front of each asset with no rewiring or downtime. Deploy Zero-Trust on-premise, on top of your critical production systems.

OT cybersecurity
Secured by design. Adopted by default.
Security and compliance are the technical win, and Access Gate already handles them: visibility, protection, logs, on-premise. The organizational win comes next: expose really simple, secure services operations actually want, and pull teams and machines in instead of watching them route around you. Make their day easier, accelerate the business, gain visibility in return.
The easier path becomes the secure one. That's how security sticks.
Remote access
Grant vendor and staff access to machines, through the proxy, never the flat network.
Protocol gateways
Let production data flow out, inspected and controlled, not through an open port.
DNS & time
Machines and apps resolve names and share accurate time, so OT just works and logs line up.
File sharing
Swap USB sticks and open shares for file access through a simple login built for operators.
Historian & dashboards
Expose production data on-site, without punching a hole to the cloud.
Update server
Deliver patches from on-site proxy, balancing patching requirements with a secure architecture.
Trusted by manufacturers and critical industries.
