“Secure Email” is a salesforce native application which allows the customer to send and receive encrypted emails inside the salesforce. It’s all about security, encryption, and ease of use. The standard salesforce emails are not secured by nature(in transit and at rest).
Paubox Encrypted Email is designed for ease of use for both senders and their recipients. Eliminating extra steps, like plugins, keyphrases, and portals. Paubox is also the only email encryption solution to meet HITRUST CSF certification, which means it meets essential regulatory and industry-defined requirements.
