New Policy Management Infrastructure

ES ClearPoint PMI (Policy Management Infrastructure) provides a single point of control for policy and administration, increasing deployment speed and effectiveness, reducing Total Cost of Ownership and increasing Return on Investment.

"Defining the policies means setting up the rules which conduct electronic communications into, out of and within the organization. The larger the organization, the more complex the rules," commented Rutherford.

ClearPoint PMI conquers the complexity that is inherent to large organizations by combining the full power of ClearEdge gateway e-mail and ClearSecure encrypted messaging under a common interface, and enabling policy distribution and replication.

New Secure Encrypted E-mail

ES ClearSecure offers all aspects of e-mail security -- authentication, encryption, message integrity, non-repudiation and audit. It provides an inexpensive, easy-to-deploy mechanism for encrypting e-mail and delivering it to virtually any recipient's desktop. ClearSecure's "Send Anywhere" message delivery technology eliminates the need for message recipients to install client software and manage specialized encryption keys. The encryption technology employed in ClearSecure is the Advanced Encryption Standard (AES), which is an official U.S. government standard.

Enhanced SMTP Gateway E-mail Management

ES ClearEdge 4.9 enables large, complex organizations to enforce e-policy management for inbound and outbound e-mail communications at the Internet SMTP gateway -- all within the ClearPoint Policy Management Infrastructure. ClearEdge 4.9 offers a range of operational, management and performance enhancements to the previous version.

"Enterprise level software for secure content management is crucial for large organizations. Software tools that allow large organizations to manage and secure content from one point across multiple locations will be necessary as companies look for ways to maximize resources and minimize overhead," said Chris Christiansen, program vice president at IDC.

"Clearswift ENTERPRISEsuite, driven by ClearPoint PMI, delivers the world's most powerful and sophisticated infrastructure for managing and securing electronic communications within large, complex organizations. We are now delivering this solution, whilst our competitors are still only talking about it," said Rutherford.
