Redletter

Red Letter eliminates the weaknesses in conventional email which make its use risky in sensitive commercial, financial, legal and healthcare applications. It provides the sender with proof that delivery has been made to the intended recipient and to nobody else. It secures email against unauthorised interception in either direction.

Red Letter requires no installation of any new software whatsoever on either the sender's or recipient's PC, making it easy to win immediate benefits with no workplace disruption.

Unlike many other secure email systems Red Letter is used directly from the sender's existing email program, without any need for modification to the software infrastructure.

Recipients, after authenticating themselves with an agreed password, receive their Red Letter email and any attachments in their browser, transmission to which is 128 bit SSL encrypted.

Armed with a full set of auditing and tracking features, Red Letter is the ideal choice for the enterprise that wishes to deal with its customers securely and privately - something that is totally impractical with other more complex security systems such as S/MIME and PGP that require the cumbersome installation of keys and certificates.
