Voyence software is already integrated with EMC Smarts network management platform, but they could be further combined, EMC spokesman says EMC has acquired Voyence to help IT administrators keep track of both the changes made in their network and security devices and the problems that come up — which, in some cases, are related.Voyence, a privately held company based in Richardson, Texas, makes software called VoyenceControl that manages network changes and configurations on multiple vendors’ equipment. The 78-person company will be integrated into EMC’s Resource Management Software business unit. The deal has already closed, and EMC did not disclose the financial terms.EMC will keep selling VoyenceControl as a separate product for the foreseeable future, but the acquisition gives it the opportunity to further line up the software with its own, said EMC spokesman Craig Librett. Voyence’s software is already integrated with EMC’s Smarts network management platform through software adapters, but they could be further combined, he said. In addition to managing changes on network and security devices, VoyenceControl controls who can access them to prevent misconfigurations. It also helps keep track of regulatory compliance.EMC, a storage giant, is flying high on the strength of VMware, the fast-growing virtualization company it acquired in 2004. Earlier this month, it acquired Berkeley Data Systems, which provides the Mozy Online backup and recovery services. Based in Hopkinton, Mass., EMC has about 36,000 employees worldwide and is projecting 2007 revenue of $12.7 billion. Technology Industry
