About Brosix

Brosix is a business instant messaging app built around a private team network: only users the administrator adds can join, and the admin controls contact lists, permissions and which features each user can access from a web control panel. Communication is encrypted, and features include one-to-one and group chat rooms, file transfer, screen sharing, remote desktop control, a whiteboard, voice and video calls and offline messages, with chat history available to admins. Plans include fixed monthly prices for small offices, such as a package for up to 20 users, as well as per-user plans for larger teams, with a free trial. Apps are available for Windows, Mac, Linux, iOS, Android and the web. It suits small and mid-sized companies that want a controlled, private messenger where admins decide who can talk to whom.

Best for: Small companies that want a tightly controlled, private messenger managed by an admin.
