Cybersecurity in Rennes, a leading sector!

Rennes Métropole (Greater Rennes) is a bastion of European cybersecurity with its laboratories,
institutions of higher education, SMEs, and multinationals.

Brittany, a land of cybersecurity

Brittany is one of the most active French regions in terms of creating the digital security sector. This strategic position, on a European scale, ensures visibility for Breton businesses in the European cybersecurity market.

The Pôle d’excellence Cyber (PEC), a French Ministry of Armed Forces and Brittany Regional Council initiative, has naturally taken root in Rennes. As a PEC member, Rennes Métropole is highly committed to increasing the number of cybersecurity experts in the region (Destination Rennes).

Cybersecurity in Rennes

The city’s robust military and civilian specialisations, and its transition to an intelligent city, make it a unique ecosystem which furthers the growth of the cybersecurity sector on a European level. Boasting internationally acclaimed talent, research facilities with close ties to industry, and a host of startups, Rennes is becoming an attractive hub for cybersecurity – and for recruiting the people the field needs.

Rennes Métropole (Greater Rennes) has long-standing expertise in the information and communications technologies sphere with 4,200 businesses employing 38,100 people (2018 figures). Since 2014, the French Ministry of Armed Forces’ cybersecurity activities have grown to such an extent that Rennes Métropole has become the cybersecurity reference in Europe.

The Information Control Defence Agency (DGA-MI) now has a workforce of 1500, including 500 experts in cybersecurity and cyberdefence.  Rennes is also home to ComCyber, France’s Cyber Defence Command, which was inaugurated by the French Defence Minister on 3 October 2019.
