Remote and distributed teams require a convenient, productive and secure channel for internal communication. According to WFH research working from home rose five-fold from 2019 to 2023, with 40% of US employees now working remotely at least one day a week. It is also predicted that working from home will continue to grow because of the expansion in research and development into new technologies to improve remote working. Business communication tools are among those apps which help to significantly increase productivity of remote teams and in hybrid environments.

Secure business communication is essential today. Many companies put this as the highest priority and look for secure enterprise chat software for their internal communication needs.

However, to make sure the software is safe and reliable it should fulfill with the following requirements:

  • On-premises hosting or secure cloud
  • Client-server data encryption
  • Control over access to sensitive information
  • Flexible user permission settings
  • End-to-end encryption
  • Disappearing messages
  • Multi-factor authentication

However, besides security features enterprise chat software should have the following features:

  • Group chats
  • User roles and permissions
  • Video and audio conferencing
  • Files sharing
  • Screen sharing and remote control

What's the difference between server encryption and end-to-end encryption?

  • Server encryption: the encryption keys are stored on the server.
  • End-to-end encryption: encryption occurs both on the sender's and recipient's sides. It usually requires a user first to install a program or app on their device. These programs encrypt messages before they are sent and decrypt messages only when they reach the intended receiver with a similar program installed.

The main benefit of E2EE is that it protects your data and privacy. At the same time, it makes problems with data recovery and data archiving. It also does not guarantee information protection when it is delivered to a recipient's device.
