Is email encryption a secondary topic? Recent polls show that it is not, not least because of the significant increase of industrial espionage and automated email screening by intelligence services.

NoSpamProxy Encryption is a powerful gateway solution and centrally manages all of your certificates and cryptographic keys. Implementation and operation of company-wide email encryption has never been easier.

In many industry sectors such as automotive industry and grocery discounters, encrypted communication with suppliers and external service providers is a prerequisite for being awarded contracts. Invoices sent via email are being increasingly intercepted and modified. Email encryption provides legal security both for placed orders and sent invoices. By offering encrypted email communication with customers and clients, businesses can also effectively distinguish themselves from competitors.

Confidentiality at the push of a button Centralised management of email signatures and cryptographic keys by NoSpamProxy Encryption facilitates safe and easy communication between you and your partners. All certificates and cryptographic keys are managed solely at the gateway, not on the client. Therefore, user do not have to handle the keys themselves. As a result, company-wide safety regulations are automatically implemented centrally in accordance with the company’s corporate governance. Received messages are also encrypted at the gateway and available to the user. This allows access to secure connections via TLS encryption from smartphones and tablets, as well as for archiving messages in their unencrypted form.

PDF Mail: Send emails and documents securely In many cases, recipients do not have a PGP key or personal certificate at their disposal. The PDF Mail feature included in NoSpamProxy® Encryption offers a simple and easy way to securely transmit emails and documents without the use of cryptographic keys. NoSpamProxy Encryption automatically converts the email including all attachments into a password-protected PDF document. The password is automatically sent to the receiver in a text message. Alternatively, the recipient can set their own password when logging on to the NoSpamProxy Web Portal. To open the message, only a conventional PDF reader is required. PDF Mail is of particular interest to companies who want to send sensitive and personal data without using certificates, keys and encryption software.

Certificates for email encryption For both S/MIME and PGP-based encryption, certificates are required. NoSpamProxy® Encryption centralises and automates certificate management. IT administrators benefit from a variety of helpful management features.

All about Certificates

Gateway and Private Certificates

S/MIME is the de-facto standard for email encryption and requires X.509-based certificates. These types of gateway certificates are cost-efficient and easy to manage. They work perfectly with partners that also use a gateway encryption solution. If, however, communication increases with private individuals and small businesses or if optimum compatibility needs to be ensured, privatel certificates are required.

Buy Certificates

In collaboration with our partners SwissSign and GlobalSign, we offer you the opportunity to purchase private and team certificates simply and at low cost.

Background Information The email S/MIME certificate management feature in NoSpamProxy Encryption offers support for both user and domain certificates from any TrustCenter, and automatically imports public keys included in incoming email signatures. The TrustCenters SwissSign and GlobalSign are fully integrated into NoSpamProxy. The result is a secure interface between email gateway and TrustCenters which reduces workloads on IT administrators and minimises costs.

Full support for PGP-based encryption

Of course it is also possible to generate, import and manage PGP keys with NoSpamProxy Encryption. With the support of PGP-based encryption, NoSpamProxy® Encryption provides multiple options for easy sharing of encrypted data and sending of messages.
