Business Gmail users can now send end-to-end encrypted emails to anyone, including recipients using a different email service.
Gmail users can now send end-to-end encrypted emails to anyone, regardless of the recipient’s email provider. “Recipients receive a notification and can easily access the encrypted message via a guest account,” according to Google in a blog post. The company states that this ensures secure and efficient communication without requiring keys or custom software. The new feature is available for organizations with Google Workspace Enterprise Plus combined with the Assured Controls add-on.
Encrypted Messages
Gmail users who have enabled client-side encryption (CSE) can send end-to-end encrypted emails to external contacts. Recipients do not need to install additional software or tools to access the message. They receive a notification and can view the message via a guest account in a limited version of Gmail.
According to Google, the new functionality reduces the technical barriers often associated with encrypted email. Both IT teams and end users need to take few additional steps. The data remains encrypted during transport and storage, providing extra control over data protection and privacy.
The feature is disabled by default for administrators but can be activated at the organizational level or for specific user groups. Users with access to CSE can automatically use encryption when composing an email. Upon sending, a notification appears that the message is end-to-end encrypted.
