Core expertise
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.
Our 4 approaches
The right solution for every legacy problem
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.
Cost savings
Direct comparison
New purchase (replacement)
€ 150,000 – 500,000
Solvetronix
€ 20,000 – 60,000
You save
up to € 440,000
Savings
up to 80%
Typical ROI: < 12 months
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.
Cost savings
Direct comparison
New purchase (replacement)
€ 50,000 – 200,000
Solvetronix
€ 8,000 – 30,000
You save
up to € 170,000
Savings
up to 85%
Typical ROI: < 8 months
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.
Cost savings
Direct comparison
New purchase (replacement)
€ 100,000+
Solvetronix
€ 5,000 – 25,000
You save
up to € 95,000
Savings
up to 80%
Typical ROI: immediate
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.
Cost savings
Direct comparison
New purchase (replacement)
€ 200,000 – 2M
Solvetronix
€ 15,000 – 50,000
You save
up to € 1,950,000
Savings
up to 98%
Typical ROI: < 6 months
