Retarus Mail Encryption

Secure e-mail communication has been a business-critical factor for quite some time.

Protect your e-mail against unauthorized access

Companies use e-mail for most of their internal and external communication. These e-mails often contain confidential information, personal data or other content not intended for the public eye. Sending an e-mail is like sending a postcard: everyone involved in delivery or transport can read or even change the content and no one would know. A letter sent in an envelope is even more secure than an e-mail because a normal e-mail is always exposed.   

Encryption is a way to give the e-mail an envelope and comply with the Federal Data Protection Act which requires suitable protective measures to be undertaken against unauthorized access when transmitting personal data. For it is only when suitable encryption systems are used that the right to privacy of correspondence, mail and telecommunications stipulated in the federal constitution is protected.  

The standards: S/MIME and PGP

S/MIME and PGP are the two de facto standards that exist in the area of e-mail encryption today. Retarus makes use of these two standards to offer a sophisticated service (SAAS) which falls under its Managed E-Mail Services.

Digital signature

It goes without saying that the mail encryption service can be used to sign outgoing e-mails with PGP or S/MIME certificates. The service doesn’t just encrypt e-mails, of course. The signature enhances the security of e-mail communication and boosts the confidence of your communication partners.

The service

Retarus doesn't just assume responsibility for operations and encryption solutions, it also administers the keys for your users and communication partners. Finely tuned regulations ensure that confidential e-mails are prevented from being sent unencrypted.

Webmailer

The mail encryption service can also be used over an integrated and secure web-based portal. Once the communication partner has the appropriate login information, he can access the confidential messages sent to him in his inbox on this portal. You are also out of harm's way when it comes to legal issues because Retarus is responsible for satisfying the regulations set forth in the German Teleservices Act in the operation of third-party mailboxes. As an ISP, we are subject to the relevant regulations, not you. This keeps you from having to deal with messy legal consequences and makes it much easier to operate the internal company e-mail infrastructure from a technical standpoint.
