Email encryption – not really important? This attitude has changed significantly, as can be seen in many recent polls. The reasons for this lie in the significant increase in the threat of industrial espionage and automated mail-screening by intelligence services.

As a gateway solution, NoSpamProxy Encryption takes over the central management of certificates and keys. And the implementation and operation of your email encryption solution has never been easier.

In many industries, encrypted communication with suppliers or external service providers is a pre-requirement for being awarded contracts (e.g. automobile industry, grocery discounters). Invoices sent via email are increasingly being intercepted and modified. Email encryption provides legal security both for proving what orders you placed and what invoices you sent via email. By offering encrypted email communication with customers or clients, businesses can also effectively distinguish themselves from competitors.

Confidentiality is fast and easy You can communicate with your partners particularly safely and easily using central email signatures and email encryption at the NoSpamProxy® Encryption gateway. Since keys and certificates are only managed at the gateway, but not at the client, the user does not have to deal with the cumbersome job of handling electronic keys. The safety regulations are automatically implemented centrally in accordance with the company’s corporate governance. Of course, received messages are also already encrypted at the gateway and are available to the user as usual for further processing. This allows access to secure connections via SSL encryption with smartphones and tablets, as well as for archiving messages in their unencrypted form.

PDF Mail: Send emails and documents securely Very often recipients do not have a PGP key or personal certificate. For this NoSpamProxy® Encryption offers simple way to securely transmit emails and documents with the PDF Mail feature, which does not place any demands on the recipient. NoSpamProxy Encryption automatically converts the email with all attachments into a password-protected PDF document. This password is automatically sent to the receiver via a text message. Alternatively, the recipient can set their own password when logging on to the NoSpamProxy Web portal. To open the message the recipient only needs a PDF reader. PDF Mail is of particular interest to companies that would like to send sensitive or personal data without email certificates, encryption software or SSL encryption.

Certificates for Email encryption For encryption of emails, certificates are required. They can be used for the S/MIME process according to the X.509 standard, or with a PGP key. NoSpamProxy® Encryption centralizes and automates the management of these certificates. Acquisition of the certificates is automated for users. IT administrators benefit from a variety of helpful management features.

Central management of certificates with NoSpamProxy Encryption: Convinient and secure compared to client side administration

Gateway Certificate management

Multiple ways to search the central certificate database makes certificate management easy.


The central certificate database not only holds private and public keys of all users but also holds all root and intermediate certificates and their status.


Using the quarantine function for certificates makes the maintenance of root and intermediate certificates easy. No need for the admin to research certificate chains on the Web.

Gateway Certificates and Personal Certifikates

Email encryption with self service

S/MIME as common standard for mail encryption requires X.509 certificates for all end users. Gateway certificates are cost effective and easier to manage. They work perfectly with partners who also use a gateway encryption solution. If, however, communication increases with individuals and small businesses or if optimum compatibility is to be ensured, then personal certificates are necessary.

Background Information The email certificate management feature of NoSpamProxy Encryption for S/MIME supports user and domain certificates of any TrustCenter and automatically imports public keys from incoming email signatures. For quickly and easily issuing user certificates the TrustCenters SwissSign and GlobalSign are directly integrated. This secure interface between the email gateway and the TrustCenters reduces the effort of IT administration and provides significant cost savings.

PGP Mail

Pretty much better in privacy: Of course it is also possible to generate, import and manage PGP keys with NoSpamProxy Encryption. With the support of PGP Mail, NoSpamProxy® Encryption provides multiple options for easily sharing encrypted data and messages.
