Only with Messagenius you own the data and can control communication, because Messagenius is directly installed on your company’s server, and our customizable features allows you, as the top-manager, monitor the data exchanged as the supervisor. Plus, we adjust to our client’s needs, so we can add/remove/change particular features upon request being very flexible and customizable. Also we have the patented one-tap voice message system, which allows you to send voice messages with 1 tap (instead of 3 as in any instant messaging app). None of the apps above (WhatsApp, Skype, Telegram, or Slack) allow you to do so, because they are designed in a way to make you adjust to them, not them adjusting to you. And most importantly, none of them allows you for data ownership and control, so all your data exchanged through those apps is not protected at all.
