Mexico, as many developing countries, has enormous potential as its government seeks to put in place an efficient transport and communication infrastructure to accompany the economic expansion. In this context, Thales is at the forefront of providing sophisticated security systems to public and private sectors such as the centralized supervision system and the fare collection system for the Mexico City metro network. Thales also provides full Turnkey Security and Telecom solutions for oil platforms and remains a major player in Telecom and signalization for Mexico City's suburban rail network.

In the field of Air Systems, Thales has become over the years Mexico's first partner for Air Traffic Control issues.
