Messages and files transmitted through free chat apps are untraceable. Let Teampel be your business-only channel and protect data from breaches.
Actual participation is not needed for managers to see what's going on in projects. You can even secure files with permissions so that only the selected few can open them.
Teampel can be deployed in an intranet environment, physically separating your vital data from the internet. Total security.
Formalize your communications with external parties by creating guest accounts for contractors, key customers, etc. for better impression and manageability.
Even if Teampel is deployed on an intranet, it can be accessed via a VPN connection to enhance security.
Files and images sent via free chat apps have an expiration date, but those on Teampel don't. Even your first "hello world" message will be kept searchable until the end of time (given proper server maintenance).
Search all chats, projects, groups, etc. related to you through the history data and find what you need in a blink of an eye.
