Our users say Proton for Business gave them simplicity and security


"We use the best encrypted email service provider in the world. It is inspiring that more and more people are using Proton Mail and essentially saying, I am taking privacy more seriously."

Yemi Babington-Ashaye, President of United People Global

We use Proton Mail for our medical imaging practice. Migration from our self-hosted servers was seamless, and our team loves the simplicity of sending patient reports to and from our partners.
Ethan Word, IT Admin
Proton Mail customer since 2016
Previously, we had a Google account, which was then transferred through Outlook. It was constantly having issues and we wanted more security for our attorney and client data and communications. Proton Mail makes it easy. It just works.
Michael Maynes, Partner
Proton Mail customer since 2020
I have just started an engineering consulting business. Being a startup, I am somewhat sensitive to price but I don't expect email to be a major expense. I simply need it to work. My plans and contracts get delivered to my clients. I also need access on both my computer and phone. With Proton Mail, I get all of that and the security is a bonus.
Glen Sibbeston, Principal Engineer
Proton Mail customer since 2018
Our old self-hosted email server got infected by a virus. The virus opened the Outlook files and stole all the emails and addresses. Then all of our members started getting spam from our email server — that was pretty terrible. With Proton, we get a very important feature: inboxes that are encrypted and more secure than services like Google. We were lucky that we onboarded with Proton right before the pandemic in 2020 so we could easily scale our usage.

[Proton Mail’s] encryption means I don't have to worry about my mail being read before it reaches the recipient. Other companies fail to respect my privacy.
Dr. Cappelli, CEO
Proton Mail customer since 2016
Tecpron helps companies manage their IT infrastructure. Proton Mail helps mitigate endpoint and perimeter security risks that are present whenever our customers use their emails.
