Hornetsecurity also manages the certificates so that your company is permanently protected.
What is the difference between TLS, PGP and S/MIME?
With PGP and S/MIME, each mailbox has its own key. The email client (e.g. Outlook) or the mail server encrypts the email to be sent. This means that no one can read the email without a matching counter-key. However, the information from the mail header (e.g. the subject) remains unencrypted. With TLS encryption, it is not the individual email that is encrypted, but the transport. With PGP and S/MIME, all communication between the servers is encrypted. Neither the subject, nor sender or recipient can be determined in this way.
What do I have to do to encrypt an email?
Emails are automatically encrypted. The user does not have to make any settings. This guarantees maximum ease of encryption processing.
Can the encryption be deactivated?
Yes, the user can deactivate or activate the encryption, depending on the settings. In addition, the user can decide what should happen if the recipient does not use encryption.
What is a web safe?
Many companies do not yet use encryption technology to ensure secure email communication. However, it is often necessary to send emails with sensitive information. Hornetsecurity uses the web safe to enable encrypted communication with an unprotected recipient. The recipient receives a link to the desired email, which is located in a separate mailbox. The recipient can access the contents with the help of his individual access data.
