Radware

CEO: Roy Zisapel

Founded: 1996

Headquarters: Tel Aviv, Israel

Security data center vendor Radware already has an OEM agreement with Cisco around distributed denial of service (DDoS) and firewalls. Acquiring Radware would give Cisco more firepower against competitors in the space such as Palo Alto Networks and Fortinet, according to analysts.

"Buying Radware would bring Cisco more into the next generation firewall fold," said Kerravala. "If Cisco really wants to be that end-to-end security vendor, you could argue they need an NG firewall. And I think pound-for-pound, the Radware product is as good as your going to get and their evaluation is probably a quarter of Palo Alto Networks."
