Switzerland’s largest event dedicated entirely to cybersecurity will take place in a com-pletely virtual format on 10 and 11 March. Faced with the acceleration of cybercrime, it was essential for the organising committee to maintain the 2021 edition of the Swiss Cyber Security Days (SCSD) despite the health measures linked to the coronavirus pandemic, as cyber threats are not taking a break. The new concept has been entirely designed for a virtual environment. Conferences, seminars and round tables will be accessible from a, latest-generation dynamic platform offering numerous opportunities for direct interaction between Internet users and speakers. The platform will be moderated throughout the year thanks to editorial input on topical issues related to cybersecurity.
