Secure business email and calendar, trusted by millions

Start by signing up for a Proton Business plan. Afterward, you'll need to set up your business email domain. Once that's done, create your organization, set up user accounts for your team members, and migrate any existing emails to Proton with the Easy Switch feature.

A user is an individual account that belongs to your organization or group — someone who can access Proton's secure services under your organization's umbrella. The user's account settings can be configured by an administrator.

An administrator holds full control over your organization's settings and management. They can add or remove users, change roles, and manage billing and storage allocations. It's possible to have one or more administrators.

When creating company email accounts, administrators can set private or non-private users. With non-private users (the default setting), administrators can view and manage the emails and account settings of users. In contrast, the emails and data of private users are accessible only through their own login credentials. If administrative intervention is needed, the user must explicitly grant permission.

Proton itself does not have access to the emails of any user in your organization, regardless of whether the account is private or non-private.

Proton accepts credit and debit cards, PayPal, Bitcoin, cash, and bank transfers.

You can switch to a different plan anytime from your Proton Account dashboard.

If you need more storage space, simply add more users and reallocate that storage or upgrade to a plan that offers more storage. For large organizations, you can customize your storage with a Proton Enterprise plan by contacting our sales team.
