Welcome to BSides Lisbon, the premier technical information security and cybersecurity conference in Portugal!

It is a community organized, not for profit, conference started in 2013, part of the BSides community.
Our event provides a platform for the information security community to come together and share their knowledge and experience, with a wide range of topics and speakers, from experts in the field to those just starting out.
We are proud to provide a safe and secure environment for attendees to learn, network, and have fun. We strive to make sure that everyone feels welcome and respected, and that our event is a positive experience for all.

🎟️ Tickets tend to sell out quickly, so make sure to set a reminder—we want everyone to have a fair chance to attend.

🥗 New Meal Policy:
In recent editions, we’ve seen a growing amount of food waste.
This year, while we’ll still cover part of the cost of meals, attendees will be asked to contribute a small amount if they want lunch.
This helps us be more sustainable and ensures meals go to those who truly intend to enjoy them. Thank you for understanding!
