Operational environments must balance long-lived assets with increasingly dynamic conditions.
Industrial networks are full of systems that are too old to update yet too vital to retire.
They control essential operations, making replacement risky.
They cannot be patched to today’s security standards.
They leave compliance gaps auditors can’t overlook.
This tension leaves manufacturers stuck: pay millions to upgrade, or accept the risks of aging infrastructure.
Trout gives you a third option: protect what you already have. Instead of exposing legacy equipment directly, we wrap each device in its own micro-DMZ enclave.
That means:
Threats never reach your vulnerable assets.
Operators and analytics still see the data they need.
Compliance frameworks recognize your controls as modern and valid.
The device doesn’t have to change — the protection around it does.
Benefits at a Glance
Modernization doesn’t have to mean disruption.

Fast rollout
Protection in days, no need to stop production.

Stronger security
Legacy systems isolated from modern attacks.

Save budget
Avoid costly redesign projects and extend the life of legacy equipment.

Audit-ready
Activity logs and access controls mapped to CMMC, NIS2, IEC 62443.

Smooth transitions
Overlay architecture adapts as your network evolves, without starting over.
