Message confidentiality, integrity and authenticity are basic prerequisites for tactical communication. However, these criteria are frequently disregarded, especially when transferring messages via e-mail, even though the internet is an uncontrollable transmission medium and is not suitable for classified information.

The incompatibility between different solutions for secure e-mail and their often cumbersome usage has produced lower levels of user acceptance so far. With these factors in mind, the development of cv act s/mail was focused not only on the implementation of advanced security functions, such as those based on Elliptic Curve Cryptography (ECC), but also on user-friendly integration into existing e-mail clients and the interoperability between different e-mail platforms.

End-to-end security by encryption (confidentiality) and digital signatures (integrity and authenticity) together with a comprehensible and easy to handle user interface provide the ultimate security for message transfer.

cv act s/mail is the market-leading e-mail security software for authorities and private enterprises with high security demands. As a plug-in for the popular e-mail clients Microsoft Outlook, IBM Lotus Notes and Novell GroupWise, cv act s/mail is the ideal solution for customers looking for the highest security standards, along with a seamless integration into their existing environment and workflows.

The software is continuously enhanced to meet current and future requirements. cv act s/mail is the only solution available that is approved for information classified "NATO RESTRICTED" as well as "RESTRICTED" according to German federal law.

Given the exceptionally high demands on security and usability in this area, the functionality of cv act s/mail goes far beyond the standard e-mail products. It encompasses extensive smart card support, central administration capabilities as well as support of revocation lists (CRL) and OCSP (Online Certificate Status Protocol).

The architecture of the e-mail plug-in deserves particular mention. It not only fulfills the highest security demands, but also provides a seamless integration into heterogeneous IT infrastructures. Moreover, within custom development projects extensions to its functionality and the supported interfaces are easily realizable due to the modular design of cv act s/mail. The top grades regularly received for the interoperability tests initiated by the Federal Office for Information Security (BSI) provide proof of the concept.
