The Open Security Conference is an open space conference - yet what does that actually mean? 🤔 Some describe the experience as an ongoing hallway track, some as a summer camp experience. We say it's both and more! Participants co-create what's going to happen. 😃 1/2

Gender intersects with race, disability, class, sexuality, age, and many other aspects of our lives. There is still work to do. So today, let's listen, question what we take for granted and keep working towards a more equal playing field. #WomensEqualityDay #Inclusion #DEI [nazneen]

Open Security Conference @opensecurityconf.bsky.social · 26/08/2026

Who takes the notes, organises the dinner? Who carries the mental load of planning, anticipating what needs to happen? These seemingly small tasks add up, taking time and energy that could otherwise go towards more visible opportunities. These experiences are not the same for everyone.

121

Open Security Conference @opensecurityconf.bsky.social · 26/08/2026

Women's Equality Day is a good opportunity to ask a simple question: Are we actually creating equal opportunities or are we only removing the most visible barriers? Equality is also about the work we do not always notice.
