Gmail’s New Encryption Makes Secure Emails Easier

Google is rolling out a new Gmail feature that lets enterprise users send encrypted emails with just a toggle switch. Unlike the existing S/MIME-based encryption, this update doesn’t require additional software or complex certificate exchanges, making it far more user-friendly. Initially launching in beta for emails within the same organization, Google plans to expand it to all Gmail users and even third-party inboxes later this year. With this update, Gmail users can enable "additional encryption" when composing an email. If the recipient lacks S/MIME, they can access the email through a secure guest Google Workspace account.

For Gmail users, decryption happens automatically. While Google refers to this as end-to-end encryption, it’s technically client-side encryption, meaning administrators can manage encryption keys and monitor access. It’s a step forward in email security—just not full E2EE yet.
