BTS cybersecurity

Become a Cybersecurity Professional in 2 Years

The BTS Cybersecurity is a selective, practice-oriented higher-education programme designed to prepare students for operational cybersecurity roles.

Over two years, students develop the technical, analytical and professional skills required to protect modern organisations against cyber threats.

With small classes, extensive laboratory work, industry experts, and a 12-week internship, graduates are ready to join Security Operations Centres (SOC), incident response teams, security engineering teams, and cybersecurity consulting firms.

120 ECTS • 2 years • 14 students per cohort • 12-week internship

Enrollment for the 2026–2027 academic year is now closed! See section ‘Registration‘ below.

Why cybersecurity ?

The BTS Cybersecurity was created to answer this need with a practice-oriented higher-education programme aligned with current operational security practices and industry expectations.

To meet the growing demand in IT and computing-related sectors, Luxembourg requires highly skilled and qualified professionals in the field of information security.
