1. Their auditing ("Event Logs") feature is unusable. It refers to items by some magical identifier which does not correspond to the name in the vault, e.g. "Viewed password for item ebabefac".
2. Payments by anything other than Credit Card are a mess, which is a serious pain if you have a lot of users. It took us weeks and many support interactions to get something as trivial as a bank transfer sorted.
3. It's still (!) lacking a feature to actually send people passwords ... as in sysadmin creates some account for a user, presses a magical button in BW, and it ends up in the user's vault (or maybe they get a message and are asked to import it, whatever). BW recommends you use the "Send" feature, which is basically a glorified pastebin.
4. The UX is .... not great. Organization vs Personal Collection view is confusing. Every time we onboard a new user we get questions about how they should store personal passwords.
It works well enough, but I don't think the enterprise plan is worth the 60/user/year price tag.
