Spam filters control email threats by identifying potentially dangerous messages. There are two factors to consider for spam filters: the way the spam is filtered and the way spam filters are implemented. There are different approaches for filtering, like honeypots, blacklists, spam fingerprints, and text filters. Spam filters are implemented with different focuses, giving control to individual users or centralizing control with an administrator. LivePrism combines different types of spam filters and different levels of control to have a comprehensive way to manage spam. |

Spam filters identify spam by collecting messages and creating a reference to compare incoming messages to. Honeypots do this by creating a dummy account which attracts spam messages. A similar method is spam fingerprinting, which creates a database of recognized spam.
Passive filtering uses individual restrictions on blocking emails. Blacklists set lists of domains or email addresses which are always blocked and allow all others. Content rules scan messages for keywords and block any messages which violate those rules.
There are difficulties associated with trying to identify spam — honeypots are dangerous to network security, spam fingerprinting requires constant updates, and content rules produce lots of false positives and negatives. Adding another layer of difficulty is the way that spam filters are configured. Spam filters can be configured locally, by individual users. This provides flexibility for users, but makes for patchy coverage across a network. Alternatively, spam filters can be implemented centrally by an administrator, which offers equal coverage across all users, but at a loss of individual adaptability.
LivePrism unifies all of the potential spam filters and implementations in a single filtering solution that doesn’t require high administrative overhead. LivePrism uses cascading spam filters that provide collective filtering like honeypots and spam fingerprinting, text filtering, and user-configured filters for keywords and blacklists, which guarantees robust, cross-enterprise spam filters while allowing users to customize spam filters. Because LivePrism is a hosted solution, software updates, hardware maintenance, and filter updates are automatic.
LivePrism also provides business-centric features like notifications for blocked content, network-wide reporting, and virus scanning. LivePrism augments your business’s mail server infrastructure with storage, archiving, and quarantining. |
