    As a GITP supplier we provide software and system maintenance support aligned with government procurement requirements.

Solution details

Reliable backing for critical systems

Our maintenance services cover railway equipment, government systems, factory IoT platforms and enterprise IT. For SACEM data loggers and train safety computer systems, we provide continuous monitoring and technical support to keep operations running — when hardware or software deviates, engineers diagnose remotely and attend on site when needed.

Proactive, not just reactive

Beyond fixing problems, we focus on preventing them. Through monitoring platforms and predictive analytics we raise alerts before a fault affects operations — the portable relay tester predicting relay faults three months ahead is a concrete example of proactive maintenance.
