We would like to invite all those interested in cyber security to SECURE 2023. The conference will be held on 19 April in Warsaw at the Warsaw Plaza Hotel. Participation in this year's edition is free of charge. The day before, on 18 April, in keeping with the need to develop technical competence in the area of cyber security, we have prepared an offer of training sessions that will give you a better understanding of the mechanisms and tools available to those who care about this area. The workshops are closed, by invitation only.
