Perimeter IP Filtering – 1st line of defense that eliminates over 50% of spam.

The Perimeter IP Filtering is a first line of defense that rapidly identifies and denies all known spammer IP addresses so they never pass through any filters. Your network gets protected according to the following sophisticated managed service process:

• After redirecting a customer’s mail exchange (MX) record to Mailscreen, all inbound messages will be compared against an extensive Threat database of known spammer IP addresses. This Threat database is compiled and continually updated by the Mailscreen, powered by McAfee® Threat Center, based on a 24x7 analysis of worldwide email traffic and third-party real-time blackhole lists (RBLs).
• Messages will also be filtered through our proprietary WormTraq® worm and virus detection engine, which rapidly identifies and intercepts zero-hour mass mailing worms and viruses before they can enter a corporate network.
• By pointing a customer’s MX record to Mailscreen, the business can conceal its Internet-facing mail servers and remove the threat of anonymous connections, protecting the customer from Directory Harvest Attacks (DHAs), Denial of Service (DoS) and attachment .zip bombs (messages that contain heavily-compressed or nested .zip files).
• If a message includes a sending IP address found in the Mailscreen Threat database or is found to contain a virus or worm, delivery will be denied and the connection will be immediately dropped prior to the message entering the customer’s network.
