Since Telegram is used by a few start-ups and small enterprises, I figured Troop Messenger and others could be added to the list. Troop Messenger is undeniably more than a Telegram alternative. Troop Messenger offers a lot of features compared to Telegram, which is far superior in terms of providing quality. For instance, Troop Messenger groups will have great advantages compared to Telegram chatting groups such as admin super controls, advanced search filters, screen sharing within group calling, and so on.
Troop Messenger is one of the encrypted chat apps on the list and likely you've ever encountered the most secure tool. Its world-class security measures have led a few powerful nations' defense agencies to use it for defense collaboration services and political parties use it as their political campaign software. As a result, you can estimate the tool's security. You will get to see only a few tools like Troop Messenger in the market that can be delivered with all the major delivery models like on-premise, SaaS, chat APIs & SDKs, etc.
