The European Cyber Security Challenge is an initiative by the European Union Agency for Cybersecurity (ENISA) and aims at enhancing cybersecurity talent across Europe and connecting high potentials with industry leading organizations. European countries host their national cybersecurity competitions. The winners of the national contests represent their countries in the European Cyber Security Challenge (ECSC).

Similar to the ECSC, the national cybersecurity competitions consist of security-related challenges from domains such as web security, mobile security, crypto puzzles, reverse engineering, and forensics, which the participants have to solve in order to collect points. The individuals with the most points win the competition and secure a place in their national team, which will go on to compete in the ECSC finals.

CERT.BG together with cybersecurity enthusiasts is organizing the Cyber Security Challenge in Bulgaria (CSCB) which serves as a national competition. ECSC serves as an enabler for achieving a more balanced cybersecurity workforce in the whitepaper on Women in Cybersecurity.
