CUPERTINO, Calif., June 9 /PRNewswire/ -- Proofpoint, Inc., the leader in large-enterprise messaging security solutions, today announced its Proofpoint CipherTrust Trade-up Program, incenting current CipherTrust customers to switch from their existing CipherTrust IronMail appliance solution to the Proofpoint Messaging Security Gateway appliance. By purchasing one year of Proofpoint's anti-spam service, qualified CipherTrust customers can receive free Proofpoint replacement appliances as well as free subscriptions to Proofpoint's anti-spam and F-Secure-powered anti-virus services through the remainder of their current CipherTrust license term.

"CipherTrust customers who are unhappy with the level of support, effectiveness or manageability provided by their current solution may be looking for an alternative," said Gary Steele, CEO of Proofpoint. "The Proofpoint Messaging Security Gateway combines high effectiveness against spam and viruses with extremely low administrative overhead, offering significantly lower total cost of ownership than competing solutions. Proofpoint also offers a superior management interface, advanced reporting capabilities, and unique content security features-backed by Proofpoint's world-class, global support team. This trade-up program will help existing CipherTrust customers migrate to Proofpoint's lower-cost, higher-quality platform with minimal effort and expense."

To qualify for this trade-up program customers must currently be under contract with CipherTrust to protect at least 1,000 email seats, with between two and six months remaining under their current contracts. This offer is only valid through September 30, 2005.
