Entelagent Software Corp.

Entelagent Software began operations in 1996 to develop an e-mail processing engine capable of auto-archiving, providing message preview and review and data mining of enterprise-wide databases of e-mail and attachments.

The emergent product, the SAMS Online(R) scalable platform, provides real-time monitoring and post-event review of e-mail messages and their attachments, as well as infrastructure for Knowledge Management of archived e-mail messages and attachments in all media. At the core of this "content-aware" e-mail management system is a rules-based lexicon, or keyword/phrase database.

This database contains an intelligent processor that provides the ability to define preview and review rules at the individual, group, department, or enterprise-wide level, employ separate lexicons for each group in an organization (financial, technical, Human Resources, specific workgroups and branch offices, etc.), and even filter content for phrases associations, combinations, phonetics, misspellings, and backward spellings.

Support is also available for multiple languages, including European and Asian languages, to ensure global capability of the content monitoring system.
