CipherTrust Wednesday plans to announce an upgraded version of its Edge appliance that includes new features for blocking annoying and
malicious e-mail messages before they enter the corporate network.
CipherTrust Edge 2.1, available now and priced starting at $9,995, blocks inbound e-mail determined to be malicious by CipherTrust’s
included TrustedSource threat engine. TrustedSource calculates a reputation score for each IP address that send e-mail based
on sending patterns and history; e-mail send from IP addresses with poor reputations are automatically dropped by CipherTrust
Edge.
With version 2.1, the company has added the ability to detect and block inbound e-mail containing known viruses. Also with
this version, CipherTrust Edge blocks unwanted commercial messages disguised by images or other techniques, thanks to the
latest version of TrustedSource that is able to flag bad e-mail not only via the sender’s reputation, but also by fingerprinting existing spam messages and
matching them to inbound messages.
Unlike CipherTrust’s IronMail gateway appliance that sits inside a firewall and filters inbound and outbound e-mail using
a variety of techniques to trap spam and malicious messages coming in – as well as stop messages containing sensitive or corporate
information from going out – Edge sits at the edge of a company’s network and does no scanning, but instead blocks inbound
messages deemed malicious by TrustedSource. This means that up to half of a company’s inbound traffic is blocked before it
even reaches the corporate network, say company officials.
