Processing 1 billion messages every day with more than 40,000 businesses served, Postini's Integrated Message Management protects email systems by eliminating spam and viruses, stopping DoS and directory harvest attacks, guarding content, and improving email performance and availability. Here are examples of what other analysts and research firms have to say about Postini.
"When buying solutions look for comprehensive, unified, and integrated messaging security. An integrated solution will deliver greater effectiveness through multiple detection techniques, provide policy enforced messaging, and assure visibility with a single management view on how all security systems are working, regardless of network, location or mode."
Robert Mahaowald,

"Email has become the 'transaction of record' for many businesses in dealing with their customers and suppliers. It is simply unacceptable to have the availability or integrity of this key tool reduced by junk email or event server outages. Given the filtering and other services provided by vendors such as Postini, we're not surprised by the growth in customer traffic they are experiencing."

"The major problem with current spam filtering software is that it works inside the corporate firewall without relieving corporate mail servers of the increasing burden of handling and storing spam messages. The same issues exist with current antivirus software, which scans messages and attachments once they've entered the corporate IT perimeter. Both systems require day-to-day hands-on intervention from IT personnel. This clearly is a security model that is not maximizing ROI, but it endures because until now, there have been no alternatives.
"[Managed service providers like Postini] approach the e-mail security market from a different perspective that may very well provide a higher ROI potential than other current solutions...A company using Postini changes its mail server DNS entries so that the e-mail security company becomes the first line of defense. Because Postini's data center sits outside the corporate firewall, it offers a level of security that was not possible before."
Beyond Spam: E-mail Security Services

"One of the fundamental advantages of [Postini Threat Identification Network] PTIN is that it can help an organization thwart directory-harvest attacks, a spammer practice that harvests e-mail addresses from e-mail servers and thereby reduces server performance dramatically."
