How 10,000+ businesses around the world ensure compliance
Data Processing Agreement
Proton Mail has a Data Processing Agreement (DPA) with business users detailing the specific rights and obligations of each party, as required for GDPR compliance.
Because emails are protected with end-to-end encryption, your Proton Mail inbox meets GDPR data protection-by-design standards.
Proton Mail does not have access to the contents of emails on our servers, thanks to zero-access encryption(new window). This limits your vulnerability (and liability) in case of a data breach.
Show your clients you care about their security and confidentiality
Secure no matter what
Communicate securely with your clients, vendors, and contractors, even if they don’t use Proton Mail.
Proton Mail is compliant with GDPR, protecting your data and reducing the risks of data breaches by design.
Your email’s privacy is governed by Swiss laws, which offer some of the strongest privacy protections in the world.
Easy access to secure email for your team anywhere
All emails exchanged within your business are automatically encrypted by default, no add-on or plugin required.
PGP encryption is automatically applied within your favorite email solution, like Outlook, Apple Mail, or Thunderbird. No need to retrain your team on a new tool.
On a browser or mobile
Proton Mail is also available on your web browser and through our iOS and Android apps.

Proton changed their life
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.
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.
