There is nothing like attending a face-to-face event for career networking and knowledge gathering, and we don’t have to tell you how helpful it can be to get a hands-on demo of a new tool or to have your questions answered by experts. Fortunately, plenty of great conferences are coming up in the months ahead. If keeping abreast of security trends and evolving threats is critical to your job — and we know it is — then attending some top-notch security conferences is on your must-do list for 2025.
From major events to those that are more narrowly focused, this list from the editors of CSO, will help you find the security conferences that matter the most to you. We’ll keep it updated with new conferences so check back often. While we don’t expect this calendar to be comprehensive, we do aim to have it be highly relevant. If there’s something we’ve missed, let us know. You can email your additions, corrections and updates to Samira Sarraf>.
