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
As an organization defending press freedom and access to information, privacy is both an ideal and a requirement. When we revamped our email communication architecture, Proton Mail provided adequate cornerstones: internal E2EE, audited open source and a growing secure ecosystem, thus allowing us to fulfill the latter and to approach the former.
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.
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.
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.
Our old self-hosted email server got infected by a virus. The virus opened the Outlook files and stole all the addresses. Then our members started getting spam from our email server — that was pretty terrible. With Proton, we get inboxes that are encrypted and more secure than services like Google.
[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.
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.
