Security hardware/software stocks rally in response to FireEye/Mandiant

|By:, SA News Editor

Several security hardware and software vendors are trading higher in response to FireEye's $1B+ acquisition of cybersecurity software/services firm Mandiant, and perhaps also FireEye's Q4 guidance hike. The acquisition, which comes six months after Cisco agreed to buy top intrustion prevention system vendor Sourcefire for $2.7B, is fueling hopes the industry will see additional M&A.

KEYW (KEYW +9.9%), a cybersecurity software/services provider for defense and security agencies, is the biggest gainer. Other winners include Palo Alto Networks (PANW +3.6%), Barracuda (CUDA +3.2%), Imperva (IMPV +2.4%), Proofpoint (PFPT +5.3%), and Qualys (QLYS +2.3%).
