Since its creation in 2017, the Before has established itself as one of the highlights of the Cybersecurity Conferences. This day, which combines conferences, working committees, meet-ups and round tables, has become a real moment of high-level discussion and reflection for the participants. In five editions, the Before has been able to develop its themes to reflect the issues facing digital security experts. Geopolitics, the resilience of systems (and individuals ...), crisis management, technological innovation, sovereignty, ... so many subjects (we cannot cite them all) whose approaches have adapted to current events and to the maturity of organizations.
