Legacy modernization
instead of replacement.

In 90%+ of cases, modernization is cheaper than replacement — often by 70–98%. We start with reverse engineering: we fully understand your system before writing a single line of new code.

The right solution for every legacy problem

01

Replace legacy languages

The problem

Control code in Pascal, assembler, or legacy C — nobody understands or maintains it anymore. Replacing the controller: €150,000–500,000.

Our solution

We reverse-engineer the code end‑to‑end, understand the logic without documentation, and rewrite it in modern C++, Python, or TypeScript — on your existing hardware.

02

Firmware upgrade without hardware replacement

The problem

Legacy firmware has known CVEs, no vendor patches, and no sustainable update path. Typical recommendation: full hardware replacement for €50,000–200,000.

Our solution

Firmware reverse engineering: we analyze boot chain, flash memory map, and device protocols; rebuild secure, maintainable firmware; and deliver signed OTA updates with rollback support — so your existing hardware can stay in operation.

03

Replace EOL components (drop‑in)

The problem

Core IC discontinued. Spare parts: €5,000+ each. If it fails, production stops. New machine: €100,000+.

Our solution

PCB reverse engineering: reconstruct schematic, characterize the EOL chip, select a modern drop‑in replacement, and update the PCB layout for the new IC.

04

Legacy protocol bridge

The problem

New MES/SCADA software can’t talk to the old machine. The vendor is gone. Replacement: €200,000–2,000,000.

Our solution

Passive protocol reverse engineering of serial/bus traffic. We build a custom bridge that translates proprietary protocols into MQTT/REST/OPC‑UA.
