Welcome to the official account of the Open Security Conference (#osco), the people-centred international gathering for everyone interested in cybersecurity.

Osco presents a different concept of security conference - literally from the community, for the community! It offers a platform to ease the learning curve in cybersecurity and provides the opportunity to learn, discuss, and teach.

#osco25 is over. #osco26 awaits!
Join us November 5-8, 2026 in Rückersbach, Germany. Visit our website to learn more, and follow to stay up-to-date.

Run by @0xKristof, @cisokeener, Daniel, @hans, @Gronner (gr), @IsItArtOrTrash, Kush, @lisihocke (lisi), @nazneenr, @realn2s (cl), and @seism0saurus (seism0saurus)

All my opinions are that of my employer but they don't know it yet & I am not telling you were I work. Apropos: If you need some idiot to kick computers for purposes of making them secure hmu, this job fucking sucks (vulnerability management, automation/engineering for your soc/isrt, ...).

PFP by a lizard that I am pretty sure transitioned at some point but I kinda lost contact with around the same time so I might only know their deadname & at this point it's too awkward to seek them out & ask. So instead I am going to credit them by their last discord handle I am aware of: fuck, md
