WorldSecure Client delivers the first S/MIME solution available to that installed-base in a completely integrated manner.WorldSecure plugs into existing Lotus Notes or cc:Mail systems and offers complete encryption and digital signature services. Lotus users can now secure their business communication and exchange sensitive information directly from the e-mail application that they currently use.

WorldSecure Client delivers that functionality to Lotus Notes and cc:Mail users in a fully interoperable way, allowing them to exchange secure e-mail with their trading partners," said Shannon Hakesley, product line manager for Worldtalk Corporation.
