My company has been using bitbucket for a few months now and I'm loving it, but there are older commits that I would prefer to hide. The concern is that as a smaller company today I can trust a handful of staff, but in the future trade secrets need to be better protected than I was doing at the time and I'm looking for something to act as a virtual undo button. Any ideas? I was hoping that maybe the "archive" feature might achieve this result, but I am unsure of who has access to archived commits.
