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

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.
