ICT - Electronics for critical systems

Bull, as a leading provider of critical systems, offers high-level solutions and services that draw on a combination of technical skills (in microelectronics and electronics, embedded systems…) and industry sector know-how (in transport, energy, critical infrastructures, aerospace, healthcare, seaborne and defense systems…).

Security is a precise discipline: closely aligning with the operational environment; choosing perfectly compatible; having in-depth understanding of every aspect of the project… In order to design and implement solutions that offer the best possible levels of security and resilience it is essential to be able to call on a broad spectrum of technical skills, such as those offered by Bull.
