Email encryption

What is email encryption?

Email encryption protects the content of emails from unauthorised reading. Instead of being transmitted in plain text, messages are secured so that only authorised recipients can read them.

What methods are there?

Common ones are transport encryption (TLS) between the servers and content encryption via standards such as S/MIME or PGP, which encrypt the message itself.

Why does email encryption matter?

Emails often contain sensitive or personal data. Without encryption they can be read in transit. The GDPR requires appropriate protective measures.

How SecureCloud supports secure communication

For the secure exchange of sensitive data, SecureCloud offers encrypted transmission and protected shares from Germany, GDPR-compliant and BSI C5-attested, as an alternative to unencrypted email.

What is the difference between transport and content encryption for emails?

Transport encryption (TLS) protects the connection between the servers. Content encryption (for example S/MIME, PGP) encrypts the message itself, so that only the recipient can read it.

Is a normal email secure?

Without encryption an email is largely transmitted in plain text and can be read by others. Sensitive data requires additional protection.

How do you send sensitive data securely?

Via encrypted methods or a secure data exchange with protected shares, instead of sending sensitive files unencrypted by email.
