Mirapoint offers policy enforcement on email security device

Mirapoint has launched a new email security appliance which it claimed is the first device to enforce centrally managed email policies on the box itself without relying on IT resources behind the firewall.

The company said that adding an embedded policy engine to its RazorGate email security appliance would result in a reduction of total network traffic and load on the corporate directory and would also close holes in the firewall.

According to the company, the appliance's embedded policy engine enforces recipient validation and recipient-based policies without querying the corporate directory through the firewall for each message.

Only email addresses and policy service attributes are loaded into the policy engine; no passwords or other sensitive information are stored outside the firewall. Since there is no need for queries from the RazorGate to the corporate directory server, administrators can close off access to the corporate directories through the firewall, said the company.

Analysts said that having an embedded directory on an email security appliance means that enterprises can protect their infrastructure from deluges of spam.

"To be able to deal with regular flare-ups of the chronic spam problem that is expected to reach 40bn spam messages being sent daily in 2007, enterprises will need high performance messaging security solutions that can effectively protect email users against spam over the long term," said Mark Levitt, vice president for Collaborative Computing and the Enterprise Workplace research at IDC. "Having an embedded directory could make this process easier for enterprises."

The appliance is expected to retail for $5,250 (£2,625).
