Since this story was originally reported, it has been updated to correct a misspelled name in paragraphs six and eight.MessageLabs launched on Monday encrypted\u00a0instant-message (IM) software, targeting companies that use consumer IM clients for collaboration and document sharing.The company\u2019s Enterprise Instant Messenger (EIM) is derived from MessageLabs\u2019 October acquisition of Omnipod, which focused on IM and file-transfer services, said David Hahn, group product manager. The software addresses some of the concerns raised around increased use of IM in the enterprise, such as confidentiality, compliance and intellectual-property leaks.EIM is compatible with IM software from AOL, Yahoo and Microsoft. However, encrypted messages can be sent only using the private IM network provided by the software.EIM offers reporting and management functions through an administration console. An administrator can restrict the IM networks that employees use and control their screen names. EIM can log and archive chat for compliance requirements, Hahn said. Within the next year, MessageLabs will release a "hygiene" service that scans IM traffic on different clients for malware and "spim" (unsolicited chat messages from unknown users),\u00a0Hahn said.EIM comes in three versions. Connect, the most basic package, provides secure chat on a private domain. Communicate adds logging, archiving, file sharing and compatibility with AOL, Microsoft and Yahoo. The highest-level package, Collaborate, offers integration with collaboration software from WebEx Communications and Salesforce.com,\u00a0Hahn said. Pricing is per user per month, and ranges from US$2 to $7 depending on the number of users and the package selected, he said.-Jeremy Kirk, IDG News Service (London Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
