Symantec to Divide Into Storage and Security Businesses

Symantec Corp. said it’s splitting into two companies, a move that reverses a decade-old expansion effort by the biggest maker of security software.

Symantec said in a statement yesterday that its cyber-security and data-storage divisions would become separate publicly traded companies. The Mountain View, California-based company said it made the decision after an extensive business review and had concluded it needed to be nimbler and more focused.
