Signal is an end-to-end encrypted messaging application that distinguishes itself from competitors like Messenger and WhatsApp through its open-source technology and the use of the Signal protocol for encryption. It encrypts messages before they leave the sender's device, ensuring that only the intended recipient can read them. However, its security is tied to the user's device, and vulnerabilities such as weak passwords and unprotected devices can compromise message integrity. Despite its strong encryption, Signal may not meet the stringent security protocols required for sensitive government communications, particularly due to its message deletion feature and the lack of support for record-keeping. The app is considered secure for everyday users, but may not be suitable for high-stakes governmental communication. The rise in cyber threats underscores the need for secure communication channels, leading organizations to consider encrypted messaging solutions like Signal, while also evaluating alternatives within the encrypted messaging landscape.
