GDPR compliance is easier with encrypted email

Proton Mail makes email security easy with automatic encryption and an easy-to-use interface.

Encryption is an effective way to achieve GDPR compliance

The GDPR recommends encryption

The EU's General Data Protection Regulation imposes tough rules for securing personal data — and steep penalties for non-compliance.

How 10,000+ businesses around the world ensure compliance

Data Processing Agreement

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.

End-to-end encrypted mailbox

End-to-end encryption

Because emails are protected with end-to-end encryption, your Proton Mail inbox meets GDPR data protection-by-design standards.

Proton has zero access to your data

Zero access

Proton Mail does not have access to the contents of emails on our servers, thanks to zero-access encryption. This limits your vulnerability (and liability) in case of a data breach.

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.
