End-to-End Encryption Explained: What Does It Actually Protect?

End-to-end encryption (E2EE) is one of the most discussed concepts in secure messaging, but many users don't know what it actually means.
In a typical E2EE communication system, the message is encrypted on the sender's device and can only be decrypted by the intended recipient.
This is fundamentally different from simply encrypting data while it travels between a device and a server.
However, encryption is only one part of privacy.
Users should also consider metadata, backups, data retention, account security and the platform's privacy policies.
Privacy-focused messaging platforms such as Signal, SimpleX and Vaarta use different approaches to secure communication.
Understanding these differences can help users make better decisions instead of choosing an application based only on popularity.
