OPEN-XCHANGE, the German web based productivity service provider, has announced an encryption product called OX Guard.
OX Guard is described as a "fully integrated email security tool". It requires no technical knowledge to set up and works with one click.
Messages are sent with PGP encryption using RSA public/private key pairing designed to keep all data away from prying eyes.
"We are not trying to re-invent the encryption wheel," said Rafael Laguna, CEO of Open-Xchange. "Instead, what OX Guard delivers is a secure and usable solution for everyone, helping service providers to rebuild the trust that privacy issues have destroyed.
"Everyone has the right to protect their data and we are upholding that right by making encryption user-friendly."
The "baked in" web based offering includes email retraction and timeout, secondary passwording and encrypted file sharing with storage and multi-server scalability.
If a non-user receives an OX Guard message, they receive a clear text message with instructions on how to access and decrypt the message.
Email and files are protected with symmetric AES keys and then the encrypted data is encrypted further with RSA public/private keys. Files are stored on Open-Xchange servers, but the organisation has no way of decrypting the data.
This level of encryption also appears in the main Open-Xchange suite which we profiled in an interview with Mr Laguna earlier this year. Last weekend protesters lobbied GCHQ over its surveillance schemes and those of its American counterpart, the US National Security Agency (NSA). µ
