Whitepaper: Next-generation Reputation Technology

Proofpoint Dynamic Reputation and netMLX

connection management whitepaperFor most organizations, inbound message volumes (composed primarily of spam email) increased dramatically over 2006 and this trend continues in 2007. This continuing rise in email volume presents a new challenge for organizations. How can they most effectively manage this increased message volume and reduce the impact of massive spam storms without “breaking the bank?”

Reputation services are a natural component of any email security solution because they can shed large amounts of mail traffic at the connection level. Effective email security solutions should be able to deliver 99% or higher anti-spam effectiveness, with 80% volume shed rates at the connection level. This level of spam accuracy can be delivered by a powerful anti-spam technology, while this level of shed rates can be delivered by a reliable reputation service.
