What is End-to-End Encryption?

Definition

End-to-End Encryption

End-to-end encryption (E2EE) is a security method where messages are encrypted on the sender device and can only be decrypted by the recipient device, preventing third parties, including the service provider, from accessing the content.

Understanding End-to-End Encryption

WhatsApp implements E2EE as standard in all personal conversations, which has been fundamental to the trust of its 2 billion users. However, it is important to understand that when a business uses the WhatsApp Business API with chatbots, messages are decrypted on the business server to be processed by the bot. This is necessary for the AI to read and respond. Tecca manages this responsibility by implementing encryption in transit (TLS), secure conversation storage, and strict data protection policies to maintain customer privacy during automated processing.
