1981–2026: 45 Years Serving French Critical Systems

From 1981 to 2026, Milesys designs and manufactures critical systems in France for infrastructures where failure is not an option. Four decades serving public transport, airports, and defense.

An Industrial Journey

Founded in 1981, the company quickly specialized in emergency communication equipment: call boxes, intercom systems, and safety public address systems. Products designed to last fifteen to twenty years in the field.

Across technological generations — from copper to IP, from analog to digital — the same high standards have been maintained: robustness, maintainability, and compliance with railway and PMR standards.

French manufacturing is not just a marketing claim; it's essential for maintaining control over products with a long lifecycle.

Design, electronic boards, assembly, and testing are all carried out in-house. This vertical integration guarantees traceability and parts availability throughout the entire operational lifespan.

“Some equipment installed in the 1990s is still in service. That's our best proof of reliability.”

Today, Milesys solutions are used in networks operated by SNCF, RATP, and the Grand Paris stakeholders, as well as airport and defense sites.

The Next Forty Years

Cybersecurity for embedded systems, centralized supervision, hardened IP intercom systems: there's no shortage of projects. The roadmap remains true to the original promise — critical systems designed to last.
