Enterprises seeking relief from the rising volume of spam and viruses got more help this week as several vendors rolled out tools and services designed to thwart e-mail-based attacks.

    To that end, MailFrontier (Profile, Products, Articles) this week introduced Version 3.5 of its MailFrontier Gateway product line, featuring new Time Zero technology that aims to block viruses when they first hit the network. The MailFrontier Gateway lineup also fights spam and phishing.

    A big challenge facing enterprises is the gap of 4 to 24 hours between when a virus breaks out, typically called time zero, to when anti-virus vendors have a signature available to block the virus, said Gleb Budman, senior director of product management and business development at MailFrontier .

    "Once in place the signatures work well, but the problem is that [enterprises] are open and unprotected during that whole stretch," he said.

    The Time Zero technology uses a combination of predictive techniques, tapping statistics, and heuristics to identify suspicious attachments; responsive efforts to block suspicious e-mail messages; and a set of virus signatures form partner vendors McAfee (Profile, Products, Articles) and Kaspersky. Another new partner, Avinti, offers additional anti-virus protection with a virtual machine technology.
