Frequently asked questions

What is Proton Business Suite?: Proton Business Suite combines all the secure productivity tools you need to run your organization under one account. The plan includes email, calendar, password manager, VPN, and cloud storage. From your administrator account, you’ll be able to add and manage users, enforce security settings, allocate storage, and more.
What if I don’t need all the Proton business apps?: You can choose plans specific to your needs. We offer flexible business plans for Proton Mail, Proton VPN, and Proton Pass. If your team only needs email and calendar capabilities, you can start with Mail Essentials or Mail Professional. Otherwise you can get Proton Business Suite, which allows administrators to adjust access rights.

Can I use my existing business email if I switch to Proton?: Migrating to Proton is simple. You can keep your email addresses and easily migrate all your emails, calendar events, logins, files, and more. Live support is also available with our Support team.
Learn how to get started with Proton Mail.
Is Proton more secure than other business solutions?: Unlike Google, Microsoft, and others, we use end-to-end encryption to prevent hackers or anyone else (including us) from accessing your data on our servers.
We also help your team use strong passwords and block attacks at the source. For example, our Proton Sentinel security program uses AI and human analysts to monitor for and block account takeover attacks.
I have a few specific needs. How can I find out if Proton is right for my business?: Proton is built for any business — from sole proprietors to large enterprises. Search our support articles for details about our products. Or simply contact our team and we’ll get back to you quickly.
