VeriSign unveiled enhancements to its Email Security Service on Monday, adding new spam filtering options and expanded administration tools.
The managed e-mail service is used by enterprises that want a third party to receive and filter messages before forwarding them to company servers. Company e-mail is routed to a VeriSign datacenter where it is filtered using client policy rules and scanned for spam and viruses. Blocked messages are held in quarantine, and end users can check the quarantined mail through a Web browser to see if any legitimate messages are caught, and if so, forward them on. Alternatively, VeriSign can tag spam and forward it for internal processing.
VeriSign said it has added more spam filtering options to the service, and the ability to quickly update the rules engine for swift detection of new viruses.
The Mountain View, California, company is also offering what it calls "preemptive" virus protection, whereby it places suspicious e-mails on hold until the antivirus engine is updated to add new patches to remove the virus.
New administrative tools include group filtering and improved user management through directory integration, VeriSign said. Enhanced policy and content filtering also allows administrators to block malicious content in archived attachments, including .zip and .tar files, through deep scanning, VeriSign said.
Apart from the new features, which VeriSign is showing off at the Lotusphere show in Orlando this week, the company said that Internap Network Services has signed up to be a new channel partner for the e-mail service. Internap already sells a range of VeriSign's managed security services.
VeriSign first launched its Email Security Service in June, pitting it against similar services such as the one offered by Postini.
Although VeriSign did not detail pricing for the enhanced service, a notice on its Web site indicated that a typical implementation would cost US$30,000 a year, but vary according to the number of end users and services selected.
