Proofpoint Introduces V3.1 Advances to Messaging Security Solutions

Company unveils Proofpoint Messaging Security Gateway 3.1 and Proofpoint Protection Server 3.1

New machine learning classifiers and algorithms have been integrated into Proofpoint MLX, improving Proofpoint's ability to automatically detect and block malicious URLs and to identify image-based spam, which competing solutions cannot accurately catch. These ongoing MLX enhancements are automatically made available to all Proofpoint customers via the Proofpoint Dynamic Update Service.

Sender Policy Framework (SPF) Support
The 3.1 software and appliance now support the SPF sender authentication standard to help defend against email address spoofing and phishing attacks. SPF records can be checked for all incoming email messages and policies can be configured to take action on the success or failure of SPF record checks.

Pricing and Availability
The 3.1 versions of the Proofpoint Protection Server software and Proofpoint Messaging Security Gateway appliance will be generally available in July 2005. Proofpoint's anti-spam, anti-virus and content security features are sold as individual modules. Annual pricing for these modules is based on the number of email inboxes protected and range from $2 to $40 per user per module.

Pricing for the Proofpoint Messaging Security Gateway appliance begins at $6750 plus annual user license fees.
