Privacy and security for your business

Secure business email, calendar, VPN, and much more, built on the principle of your data, your rules.

Support your compliance objectives

Easily comply with regulations that require personal health information, financial documents, and other sensitive data to be protected.

Security through transparency

Proton was founded by scientists, and we believe in research, peer review, and transparency. All our apps are open source and independently audited so that anyone can use, inspect, and trust them.

Your data, your rules

Proton uses zero-access encryption and end to end encryption (PGP encryption) wherever possible. This helps ensure nobody, not even Proton, can decrypt, access, or share any of your business information. We don't serve ads and can't share your data with advertisers.

Manage your business’s email, calendar, and VPN within the admin console.

User management

As an administrator, you can add, remove, or view the access level of every user. Plus, you can add and remove storage space, set up email addresses, and reset passwords for email accounts.

Catch-all

Receive mail sent to nonexistent email addresses on your business domain, so you'll never miss a message.

Spam protection

Protect inboxes from unwanted emails, including spam and malware, to help keep your team focused and safe.

Distribution lists

Keep teams on the same page by assigning multiple users to the same email address (e.g., sales@example.com). Contact the sales team to be notified when this feature is available.

Contact lists

Easily send emails to the whole team or groups of recipients by creating contact lists.

Account transfer

When team member responsibilities change, it's easy to transfer emails to a different account.
