Cloudmark ActiveFilter: Message Filtering for Internet Service Providers
Imagine having the power to use present information to make better decisions in the past. Cloudmark ActiveFilter, can do just that by leveraging the most up-to-date data on new threats to filter messages that have been scanned minutes or even hours ago.
Taking the Time Advantage Away from Spammers
Even with the most effective message filtering and anti-spam policies in place, a small percentage of spam messages can slip through the system. These messages are typically identified by Cloudmark just seconds or minutes after delivery – and before the recipients have logged in and checked their messages. Cloudmark ActiveFilter, with patent-pending technology, enhances overall spam capture rates by continuously reviewing newly-available fingerprints to see if messages delivered to the mail store within the past several hours are actually spam.
Cloudmark ActiveFilter does not need to rescan every physical message, but instead, uses a "push" paradigm that moves or deletes only specific stored messages that have been identified as spam after initial delivery. Cloudmark ActiveFilter virtually neutralizes any advantage of advanced spam distribution techniques that try to leverage the latency in traditional spam filter updates. The result: dramatically lower levels of spam and minimal impact to CPU and disk resources.
