Google has announced that its end-to-end encryption (E2EE) feature for Gmail is now rolled out across all Android and iOS devices, enabling enterprise users to manage their electronic correspondence without requiring auxiliary tools.
Effective this week, encrypted messages will arrive as standard emails in the inboxes of Gmail recipients who utilize the corresponding mobile application. Those without the Gmail mobile app, accessing mail via other services, can view them in a web browser, irrespective of their device or email provider.
“For the first time, users can compose and read messages with E2EE directly within the Gmail app on both Android and iOS. There is no need to download extra applications or utilize web portals. Users licensed for Gmail E2EE can dispatch encrypted messages to any recipient, regardless of the recipient’s email address. This deployment merges the highest level of data privacy and encryption with ease of use for everyone, facilitating simple encrypted electronic mail for all clientele, spanning from small businesses to public sector enterprises,” stated Google.
The E2EE encryption capability is activated for all client-side encryption (CSE) users holding Enterprise Plus licenses, along with the Assured Controls or Assured Controls Plus add-ons, once administrators enable Android and iOS clients within the CSE administrator interface via the Admin console.
To dispatch an end-to-end encrypted message, Gmail users must activate the “More encryption” option by tapping the lock icon while composing a new message.
Last October, Google had also made public that Gmail Enterprise users gained the ability to send encrypted emails to recipients across any email service or platform.
Gmail’s E2EE feature leverages the client-side encryption (CSE) technical management, which empowers Google Workspace organizations to employ encryption keys that remain under their dominion and are stored outside of Google’s servers, thereby protecting sensitive documents and email communications. Consequently, messages and attachments undergo encryption on the client side prior to transmission to Google’s servers, assisting compliance with regulations such as data sovereignty, HIPAA, and export controls, while ensuring neither Google nor third parties can decipher the data.
Gmail CSE encryption was initially introduced for the web version of Gmail in December 2022 and was first deployed as a beta for Google Drive, Google Docs, Sheets, Slides, Google Meet, and Google Calendar. In February 2023, CSE became accessible to Google Workspace Enterprise Plus, Education Plus, and Education Standard customers.
The company commenced the rollout of its new end-to-end encryption (E2EE) model in beta for Gmail enterprise users in April 2025.
