Cyber security conferences or seminars are crucial for continuous learning. But the number of annual held cybersecurity events is immense. So on this blog page you will find an opinionated collection of exiting cyber security events worldwide.
I love conferences that embrace openness. This includes providing open access to slides, videos, and other materials for anyone interested, even if they couldn’t attend. In my experience, conferences that put these resources behind a paywall are never worth the effort. The true value of attending in-person security conferences or meetups often lies not just in the talks but in the meaningful conversations and connections with peers.
Please tip me if you have a non-commercial cybersecurity conference that you would like to see in this collection. In this opinionated collection I focus on:
- Non-profit, non-commercial events.
- Events run by by volunteering enthusiasts.
