Gmail and end-to-end encryption: a new era for email security

Google is revolutionizing the way Gmail users in the workplace exchange sensitive information. Thanks to a new feature, it will now be possible to send end-to-end encrypted emails to any recipient, regardless of the email service they use. This advance marks a turning point in the protection of digital communications.

Three key points to remember

  • Gmail users can send end-to-end encrypted emails to any recipient, regardless of their email provider.
  • The feature is available to organizations using Google Workspace Enterprise Plus with Assured Controls.
  • Rollout of this feature will begin on September 30, 2025, and will take place over a two-week period.

Encryption feature extended to all recipients

Google has announced that business users of Gmail will now be able to send end-to-end encrypted emails to any recipient, regardless of the email service they use. This approach aims to simplify digital communications security by removing the need for recipients to have custom keys or software.

Simplified accessibility for recipients

Recipients of these encrypted emails will receive a notification allowing them to easily access the message via a guest account. This method ensures secure viewing without the need to install additional software, greatly simplifying the user experience.

📊 Comment certains vendeurs dépassent 1 000 €/mois sur Vinted ?

Un vide-dressing occasionnel rapporte rarement plus de 200 € par mois. Mais l'écart avec les vendeurs les plus performants est plus large qu'on ne le pense : 300 à 900 €/mois pour une activité régulière (2 à 5h/semaine), et 1 000 à 2 500 €+/mois pour les profils qui traitent Vinted comme un vrai canal de vente structuré. La différence ne tient ni à la chance ni à la taille du dressing de départ : elle tient presque entièrement à la méthode (algorithme, pricing, réactivité) appliquée avec régularité.

Feature activation and deployment

Although this feature is disabled by default, it can be enabled by administrators at the organization level or for specific groups of users. Once client-side encryption (CSE) is enabled, Gmail users can automatically send end-to-end encrypted emails, ensuring greater data protection. The rollout of this new security capability will begin on September 30, 2025, and will take place over a period of fifteen days, gradually affecting all domains in the rapid and scheduled release channels.

Background and impact for Google

Google, founded in 1998 by Larry Page and Sergey Brin, has become a major player in the technology field with its suite of diverse tools and services, including Gmail. With over 1.5 billion active users, Gmail is one of the most widely used email services in the world. By introducing end-to-end encryption, Google is strengthening its position as a leader in data security and privacy, meeting the growing expectations of businesses for the protection of sensitive information.

This development is part of Google’s commitment to providing secure and effective communication solutions while simplifying processes for end users and IT teams, thereby consolidating its reputation as an innovator in the technology sector.
