http://www.thevarguy.com – Cisco Systems (NASDAQ: CSCO) apparently has stumbled in the security market. Reuters suggests the networking company may need to buy (rather than build) its way out of the situation. Potential targets mentioned include Palo Alto Networks (NYSE: PANW), FireEye, Sourcefire, Fortinet (NASDAQ: FTNT) and Barracuda Networks. But The VAR Guy has at least three other potential deals in mind. (IT news)
