ProtonMail for Business and Professionals

Swiss Privacy
Data Security and Neutrality

ProtonMail is incorporated in Switzerland and all our servers are located in Switzerland. This means all user data is protected by strict Swiss privacy laws.

End-to-End Encryption
Automatic Email Security

We use end-to-end encryption and zero access encryption to secure emails. This means even we cannot decrypt and read your emails. As a result, your encrypted emails cannot be shared with third parties.

Your data, your rules
Protect your privacy

ProtonMail is email that respects privacy and puts people (not advertisers) first. Your data belongs to you, and our encryption ensures that. We also provide an anonymous email gateway.

Open Source
Free Secure Email

We believe email privacy should be available to all. That's why our code is open source and basic ProtonMail accounts are always free. You can support the service by upgrading to a paid account.

Easy to Use
Security without the hassle

ProtonMail can be used on any device without software install. ProtonMail secure email accounts are fully compatible with other email providers. You can send and receive emails normally.

Calendar & Drive
Security with Productivity

Proton Calendar and Proton Drive extend privacy to your events and documents. Our secure email service is fully integrated with an encrypted calendar, enabling you to keep your events private as well.

Other Information

Can I use ProtonMail with my website domain name ?

Yes, absolutely. You can continue using your domain name (i.e., the name after the @ in your email address) and you will keep the history of your emails. Your inbox stays the same, just more secure.

Can I purchase additional email storage ?

Yes, we can provide you with as much storage space as your organization needs. Our Professional plan includes 5GB per user in the base plan. If you have 100 users, you will have 500 GB of storage within your organization that you can use across all 100 users. Of that 500GB, you decide how much each employee gets. If you need more, contact Ayottaz.

Can I use outlook or other email clients with ProtonMail ?

Yes, you can use ProtonMail for Outlook email clients (and other third-party clients) through a desktop computer (not supported on mobile devices).

Can administrators of an organization access employee emails and reset their passwords ?

Yes, this is an option that the administrator can select when setting up each user account. The administrator can also select to create a “Private” account, which they won’t have access to, often used for highly classified employees such as executive teams.

Where are ProtonMail servers located ?

All of our servers are in secure data centers distributed throughout Switzerland. While we don't disclose the precise location of our servers anymore, our first datacenter was in a former Swiss military bunker 1,000 meters beneath the Alps, built to resist a nuclear attack.
