ProtonMail for Business (Intro to Professional Plans)

ProtonMail’s secure email service can also be used for enterprises large and small. With our Professional Accounts, your company can now use end-to-end encryption to secure your business communications.

In this article, we will provide an overview of ProtonMail Professional accounts and how they can assist your organization in securing your email communications.

How can I use ProtonMail in my business?

Every day business employees send sensitive data through email with the assumption that the information is secure and will remain private. We have seen by the ever increasing number of data breaches (link to blog post about how the future of internet security is not holding the data), that this assumption no longer holds true. Instead a better assumption is that your organization will suffer a data breach at some point in the future. ProtonMail offers a hosted email solution to ensure your information remains secure even in the event that your business does suffer a data breach.

Getting a ProtonMail Professional Account

Signing up for ProtonMail Professional is easy, you can be up an running in a few clicks. You will first need a ProtonMail account. You can signup for a free account. Once you have your account, you can upgrade to a Professional Plan through the Dashboard tab of your account within your account Settings.

    I am interested in having an account that supports HIPPA requirements. I see that Proton reports that they are HIPPA compliant.
    I want to know what is the best option (plan) to choose if you support HIPPA and how to receive a BAA agreement?

    Thank you.
