Don't let your competitors learn your secrets! Unencrypted email can lead to leaks and other damaging effects.


Unencrypted emails can be intercepted in transit and edited to include items such as ransomware, viruses, or other malicious attacks.


Email Security is supplied with default cyber security policies, DLP policies as well as allowing organisations to add and edit their own policies for the whole organisation and/or users

Various email encryption technologies
Email Encryption supports all standard encryption technologies, including S/MIME, PGP and TLS with Perfect Forward Secrecy.

The so-called PKI-based email encryption technologies (S/MIME = Secure / Multipurpose Internet Mail Extensions and PGP = Open Pretty Good Privacy) ensure the confidentiality of transmitted messages between sender and recipient and protect the transported data using cryptographic encryption methods. Hornetsecurity’s encryption service offers this protection directly in the cloud and thus secures the transmission route completely. The TLS protocol is used to ensure confidentiality, authenticity and integrity when transmitting data over insecure networks.
Manage email encryption with minimal effort
Hornetsecurity provides IT administrators with a variety of ways to easily create and manage email traffic encryption, such as handling user certificates or customizing encryption policies.

Encryption settings can be made either globally or individually for specific users, groups or domains.
Fully automated encryption and decryption of your emails
Outgoing emails are automatically encrypted with one of the common encryption technologies (PGP, S/MIME or TLS), depending on the set policy and availability of the corresponding certificates, without any further user intervention. If the sender’s public key is available, their emails are automatically decrypted and delivered to the recipient.

Encryption of data has become a priority because of compliance requirements as well as enactment of the General Data Protection Regulation. In a organisations environment, exchange of sensitive files and information takes place primarily via email communication. Cyber criminals rely on the “Man-in-the-Middle” to pick up valuable information here. Encryption of the transmission path is essential to protect this data.
Confidential communication via Websafe
Even if the communication partner cannot receive encrypted emails, the encryption and confidentiality of email communication with those individuals is still guaranteed.
