Overview

Egress Protect

Egress Protect helps you eliminate the risk of accidental data leaks and deliberate threats in your outbound emails. Instead of relying on static rules, you get an intelligent system that learns your communication patterns to spot when you've added the wrong recipient or attached the incorrect file. It acts as a safety net that catches human errors before they turn into costly data breaches.

You can easily encrypt sensitive messages and large file attachments directly within your existing Outlook or Microsoft 365 workflow. The platform also gives you total control over your data after it's sent, allowing you to revoke access, see who opened your files, and set expiration dates. It simplifies compliance with regulations like GDPR and HIPAA while keeping the experience smooth for both you and your recipients.

Proton Drive

Proton Drive gives you a highly secure space to store, share, and sync your most sensitive files. Unlike traditional storage providers, it uses end-to-end encryption, meaning not even Proton can see what you upload. You can access your data from any device while knowing your privacy is protected by Swiss law and open-source, audited code.

You can easily organize your digital life with folders, automatic photo backups, and secure file sharing links. It is built for anyone who prioritizes privacy, from individuals protecting personal photos to businesses securing confidential documents. You get a seamless experience that integrates with the broader Proton ecosystem, including Mail and Calendar, to keep your entire digital footprint private.
