As widely acknowledged, the use of certificates is the right way to encrypt documents, to sign documents or to use encrypted network connections. But it is not sufficient to simply use the certificates: A certificate has to be valid. ValidationWorks! implements the standardized OCSP protocol to validate certificates ONLINE and check their status.

State-of-the-art Validation
An OCSP online validation has various advantages over CRL revocation checks: real-time responses, performance, interoperability, network load

Perfect Integration
ValidationWorks! extends the Microsoft-Crypto-API. Therefore all Microsoft products using this API automatically use the improved validation technology for the used certificates (e.g. MS-Outlook, Internet Explorer, etc.)

Ease of Use
Installation, use and visualisation are implemented to guarantee maximum simplicity. 

Overall Security
The validation configuration can be customized according to your companies policy. Every manipulation will be detected at once.
