WhatsApp's security model that keeps message content readable only by sender and recipient.
End-to-end encryption (E2EE) is the security technology underpinning WhatsApp, ensuring that the content of personal messages can be read only by the sender and the intended recipient — not even by WhatsApp itself in transit. It is a core reason customers trust the platform for private communication.
For business messaging on the platform, encryption protects messages in transit, while businesses and their providers may process message content to deliver service. Meta has also introduced options to help keep cloud-hosted business messaging secure.
The privacy reputation of WhatsApp, rooted in encryption, contributes to the high engagement businesses see, since customers feel safe communicating there.
Encryption underpins the trust customers place in WhatsApp, which is part of why business messages there see such high engagement.
