Past Conferences

This is our archive. To give you a better impression what you can expect at osco, we preserve the websites of the previous conferences. After each conference we persist the website at a subdomain with the year, like 2024.opensecurityconference.org. This way you can go back in time to view previous conference schedules or just see how the website and the organization team developed over time.

osco 2025

2025 was the second iteration of the Open Security Conference, and it was an even bigger success with 39 participants. That’s been a growth of 95% since the first conference 2024.
