E-mail security app thwarts spam

Sendio has unveiled its E-mail Security Platform (ESP), a network appliance that eliminates spam by using the same verification model that is used by social networking sites such as Facebook and LinkedIn, the company said.

ESP uses a process the company calls silverlisting, which utilizes a set of low-level SMTP tests to determine the legitimacy of the sending e-mail server. Silverlisting prevents up to 95 percent of unwanted e-mail from reaching the recipient server, according to Sendio.

The platform also uses sender address verification (SAV) that verifies the authenticity of first-time, unsolicited senders. It also incorporates the human element into the e-mail security process, said Kevin Bowyer, CEO of Sendio.

Unlike spam filters, Sendio's platform ensures that legitimate messages aren't routed to the spam folder, Bowyer said.

The SAV feature has proved especially helpful for heatlh-care organizations, Sendio said. Spam filters would always block mention of certain medications or health concerns, Bowyer said. ESP doesn't apply these sort of global filters on specific words or phrases.
