Legacy Asset Dilemma
Industrial networks are full of systems that are considered legacy:
They control essential operations, making replacement risky.
They cannot be patched to today’s security standards.
They leave compliance gaps auditors can’t overlook.
Manufacturers are caught in this tension: the equipment still functions, but the security and compliance ecosystem around it has shifted dramatically.

A Third Way: Protect, Don’t Replace
Trout gives a third option: protect what you already have. Instead of exposing legacy equipment directly, change the surrounding architecture.
How it works:
Create software-defined micro-DMZs in front of each legacy asset or group of assets.
Channel all access and traffic through the enclave – threats never reach the exposed device directly.
Maintain operator visibility and analytics access – the asset remains fully useful.
Generate audit-ready logs and enforce access controls to modern standards.
In short: you extend the life of the asset while upgrading its protection.
Who This Is For
Manufacturers running control systems that are no longer vendor-patchable.
Operations teams needing to protect production uptime while improving cyber resilience.
Compliance and risk leaders seeking to close gaps without asset replacement.
IT/OT hybrid environments where network redesign is costly or disruptive.

In Summary: Keep Your Proven Equipment, and Make It Secure
Most industrial networks weren’t built for the cybersecurity landscape of today. They run on proven machines — PLCs, HMIs, and control systems — that have delivered reliability for decades but were never designed with security or compliance in mind. Replacing them isn’t always realistic; production uptime, cost, and vendor dependencies make it nearly impossible.
Trout provides a practical alternative. Instead of forcing outdated equipment into modern security frameworks, Trout surrounds each legacy asset with a software-defined protective enclave. Every connection to the device passes through a hardened proxy that enforces Zero-Trust policies, encrypts traffic, and captures detailed audit logs. The result: you gain visibility, segmentation, and compliance — without modifying or interrupting production systems.
This approach extends the useful life of your legacy equipment while aligning with modern frameworks such as CMMC, NIS2, IEC 62443, and NIST 800-82. It’s a fast, on-premises solution with no cloud dependency — ideal for manufacturers, defense contractors, and operators of critical infrastructure.
With Trout, you can secure what you already own, protect operational continuity, and transform legacy risk into a manageable, auditable part of your cybersecurity posture.
Modernize your network — not your machines.
