The CNI master's (Cybersécurité des Infrastructures Numériques) at Université de Rennes trains engineers to secure complex digital infrastructure. It combines cryptography, network security and security operations with strong research foundations.

Set within one of Europe's densest cybersecurity ecosystems, the two-year programme gives students access to leading research labs and the wider Breton cyber cluster. Coursework alternates theory with practical projects and internships.

Graduates are highly sought after by security vendors, operators of critical infrastructure and research centres, benefiting from abundant career opportunities in the Rennes region.
