SecureWorks, provider of managed security services (MSS), has completed its acquisition of VeriSign's MSS business, the company announced Tuesday. The move by VeriSign aligns with a 2007 decision to concentrate on its core internet infrastructure business and divest other units. The deal, meanwhile, allows SecureWorks to bolster its hold as one of the security industry's few remaining managed services pure-plays. Terms of the deal were not disclosed. – DK
