We never intend to commercialize FSec and in the true meaning of open source and open knowledge we would like to enable everyone to attend.

Unfortunately, running a symposium on this level has costs, but we made sure everyone who wants can attend.


You sit at your comfortable chair at work and thinking on participating at FSec? but you think it's just far beyond your budget or knowledge level? Far from it. We want to make sure everybody can come, so we have come up with different levels of attendees (you can join even for free!), so we can equally work on information security problems. Come and be part of once and only moments at FSec, so you can tell your grandchildren about it. We know you want it. Now get up from that chair and start working to come to FSec. Moment you start learning for real is outside of your comfort zone (or chair zone).

If you are a student, unemployed, cannot afford a ticket or your company doesn’t want to buy you a ticket, send us (fsec-tickets @ an e-mail with the reason why you should get a free ticket. Free tickets are issued on an amount of free space basis, although we will reserve a number of free tickets exclusively for students and the unemployed. Keep in mind that those are given out on mix of first come - first serve basis and the evaluation of you e-mail where you wrote why should you get a free ticket.

This year, we won't be accepting cash at the entrance! We will be only relying on bank transfers because of financial regulations. Remember you NEED to write an e-mail a few days before the payment deadline with a reason to obtain free entrance to the conference.

We have a strict recording policy for our talks, so after the event only slides will be published from speakers that want their slides to be published. Some talks will be recorded (if the speakers explicitly wish their talks to be recorded, and they will be posted 10 months after FSec - Keep in mind, most of the talks will not be available as recordings)
