Trend Micro Network Anti-Spam Service delivers the most powerful network-layer spam protection available, combining dynamic real-time spam blocking - plus - all of the features of Trend Micro RBL+ Service. It stops spam by verifying IP addresses against an extensive reputation database with ratings based on spamming activity. It also identifies suspect behavior and blocks new sources of spam - even zombies and botnets - in real time as the mail is being sent. Updates are immediately delivered to the database - for the most reliable, up-to-the-minute protection.
Network Anti-Spam Service maintains a fully dynamic blacklist to block spam in real time at the IP connection level - before it can traverse the enterprise perimeter. This is a key advantage over application-based solutions that manage spam after it enters your network.
Dynamic anti-spam technology combines heuristics, complex algorithms, and real-time monitoring to identify suspect behavior and block new sources of spam - even zombie PCs and bot networks, which are difficult to track. The dynamic blacklist is updated in real time and blocks sources as long as they are spewing spam.
By eliminating spam, the service protects corporate networks against viruses, spyware, grayware, and other malware that use spamming tactics to proliferate. It also blocks phishing-related emails designed to steal credit card numbers and other sensitive data. Plus, it guards against directory harvesting attacks, which consume resources and lead to more spam.
Blocking up to 80% of spam before it hits the corporate network, reputation services prevent junk mail from wasting valuable time, clogging bandwidth, and hogging system resources. The costs for both storage and administrative review are greatly reduced. Plus, it scales easily - without the need and added costs for additional hardware or software.
