E-mail security solutions provider today announced its E-mail Security Platform (ESP), a robust and scalable appliance solution which entirely eliminates spam, thwarts viruses and enables dramatic time savings for users and IT administrators. ESP employs a verification model similar to the one embraced by millions of social networking users, such as Facebook and LinkedIn, and the "buddy" list model used by leading instant messaging providers such as Skype, Yahoo!, Google and AOL.

ESP combines Silverlisting, a proprietary technology which includes a set of low-level SMTP tests to determine the legitimacy of the sending e-mail server, and Sender Address Verification (SAV), which verifies the authenticity of first-time, unsolicited senders, and integrates human decision making into the process. ESP far surpasses the capabilities of current spam filter offerings and finally secures the enterprise inbox through the complete elimination of spam, Sendio said in a news release.

"It's obvious that spam filters don't work: large quantities of spam messages frequently make it into enterprise inboxes, despite the repeated fine-tuning of spam filters, and even more serious, legitimate messages are being tagged as spam and lost or delayed by filters," said Kevin Bowyer, chief executive officer of Sendio, Inc. "Unlike spam filters, Sendio's ESP ensures that spam is blocked and real messages are never routed to the junk folder. It incorporates a similar user acceptance model utilized worldwide by users of Facebook, MySpace, leading IM vendors and even caller ID."

Sendio's ESP incorporates a combination of technologies and features to enable the complete elimination of spam with minimal administrative maintenance, achieving significant time and resource savings for enterprises. Silverlisting, in combination with other features, ensures message validation while verifying the delivery of all legitimate e-mail. Silverlisting is the first line of defense, preventing a significant volume of unwanted e-mail from reaching the recipient server - up to 95 percent - freeing up network bandwidth, and system and personnel resources.

"Spam has become an epidemic problem in today's enterprise market, causing blatant business inefficiency and strain on the network," said Michael Osterman, founder and principal of Osterman Research. "With no signs of slowing, it's apparent that spam filters are not the cure-all solution to the problem. Sendio's ESP, an alternative approach to preventing spam from reaching the enterprise inbox, is certainly innovative and could be a huge time-saver for IT and network administrators in the long-run."

In conjunction with Silverlisting, ESP also utilizes Sender Address Verification (SAV) to incorporate a human element into the process. Sender authentication is not a new concept in the communications world, yet Sendio's application of SAV to e-mail is a paradigm shift - the e-mail 2.0 answer to thwarting spam and threats. When SAV is implemented in Sendio's ESP, it only sends an SAV message to a first-time, unsolicited sender.

"We had to deal with spam without blocking legitimate e-mail. For example, we were concerned that filters would not be able to differentiate between fake 'Viagra' e-mail and valid messages with 'Viagra' in the subject line. Sendio gave us back our e-mail," said Glen Malan, director, IT Infrastructure and Web Systems, Central DuPage Hospital.
