Secure team communication app for business collaboration

The most secure app for business communication and collaboration is a messaging app that prioritizes privacy and data security. It uses various methods to protect information from unauthorized access.

The set of features that such a messenger should have includes:

• end-to-end encryption (E2EE);
• confidentiality of incoming and outgoing text messages, graphic data and video files;
• multi-factor user authentication, which adds an additional level of verification before entering the application, such as a unique code or biometric data (in addition to the password);
• protection from unauthorized third-party influence (including counterfeiting of the application itself, deletion or insertion of messages by third parties on behalf of the account owner);
• "self-destructing" messages (the function allows you to set the validity period of messages, after which they are automatically deleted from the devices of the sender and recipient).

It is worth noting separately that for a secure messenger used for corporate correspondence, it is important where exactly the information is stored. Large companies prefer on-premise solutions (i.e. "on their own servers"), which allows them to control and manage data flows.

A corporate messenger is a secure app for business communications and collaboration. This is not an ordinary chat — such messengers have a wide functionality. Thus, they can be integrated with third-party services (CRM systems, internal systems, databases, mailing services).

There are a number of distinctive features by which you can accurately determine whether the app for business communication is really the most secure:

• End-to-end encryption. Many of the latest versions of popular instant messengers feature so-called end-to-end encryption (E2EE) of correspondence by default. With this type of encryption, data is encrypted on the sender's device and decrypted on the recipient's device. They travel the entire way encrypted. The encryption keys are also stored on the sender's and recipient's devices, not on third-party servers.
• Open source. Open source means that the application is available for study and security testing by external experts. This can help to detect vulnerabilities and draw attention to the program's weaknesses.
• Data storage and backups. Messenger chat data can be stored on devices or cloud servers, both encrypted and open. The most secure app for business will not store chat data on its own server.
• Disappearing messages. The ability to send messages that are automatically deleted after they are read or after a specified period of time is provided by a number of applications.
• Blocking chat screenshots. Some secure apps for business either do not allow you to take screenshots of correspondence in secret chats at all, or notify the sender that the recipient of the message has taken a screenshot.
• Two-factor authentication support. When two-factor authentication is enabled, you will need to enter a password or code from an SMS message to gain access to the application. On some devices, biometric unlocking (fingerprint or face recognition) may be available.

It is a cross-platform messenger available on computers and phones, as well as web and mobile apps for iOS and Android. Plus, the platform has built-in integration with third-party applications, including Jira, GitHub, and Trello. This app also has a number of disadvantages:

• Rocket.Chat does not have the largest tester base. This can lead to bugs in the application.
• The messenger has a large stack of solutions - to find the necessary add-ons, you will need to study a large library.
• In terms of initial setup, Rocket.Chat is less friendly to beginners than its counterparts. In particular, if you need to deploy your own server. However, such a setup is carried out only once.

Signal is one of the most secure apps for business that can be installed on a PC and smartphone. The developers position it as a guaranteed private service for communication. The application was released back in 2013, but it became popular only a couple of years later thanks to Edward Snowden. He told reporters that he uses Signal. In 2021, Elon Musk mentioned the application, and this provided an even greater surge in popularity.

In the Signal application, users chat, communicate via video, create groups - these are standard options for well-known messengers. The main differences between Signal and its analogues are that it reliably encrypts files and messages, does not collect metadata and has an open source code. The advantages of the application are as follows:

• End-to-end encryption. Thanks to this technology, messages are available only to participants in the correspondence. Developers and third parties have no way to steal information from the chat.
• Open source code. It can be found on GitHub to study for yourself. Some experts have already done this and have found the development to be reliable.
• Not collecting metadata. Applications collect metadata to study users' interests and offer them relevant advertising. The only information that the Signal application collects is users' phone numbers.

The Signal application has its drawbacks. It is not very convenient and practical, it does not provide tools for running a business, you cannot create bots, and the size of the transferred file should not exceed 100 MB.
