Networking equipment maker Cisco Systems is buying security technology developer Riverhead Networks for $US39 million in cash.
The privately-held company specialises in software that protects against attacks on corporate and telecommunications networks, such as distributed denial of service (DDoS) attacks, according to Cisco's director of business development, Janey Hoe.
"Riverhead has unique technology that's patented," she said. "It can eliminate attacks based on malicious network behaviour; learning the profiles of what's normal, detecting problems and being able to take action and respond quickly."
Cisco currently held a 10 per cent stake in Riverhead Networks and would be buying the remaining company shares in a deal that was expected to close in Cisco's fiscal third quarter, between May and August,Cisco's senior director of product and technology marketing, Jeff Platon, said.
The purchase of Riverhead Technology continues Cisco's move to position itself as a provider of secure networking products. On March 12, Cisco announced its intention to purchase secure sockets layer (SSL) virtual private network (VPN) technology company, Twingo Systems, for $US5 million in cash and last year it acquired network security software provider, Okena, for $US154 million.
"These acquisitions are all part of our strategy of bringing together various, serious components and technologies that support against threats that are known and unknown," Platon said.
"Customers will see a financially stable organisation that can enable enterprise and service provider customers to build intelligent networks that are also integrated with security for threats against business processes and services," he said.
Similar acquisitions can be expected in the future, Platon said.
Cisco would initially take Riverhead's existing products and then work to integrate that technology into Cisco's secure global networks product and service line, Hoe said.
Riverhead, with 44 employees, would become part of Cisco's Internet switching business unit, she said.
Cisco would try and keep job cuts to a minimum.
As equipment sales have decreased, Platon and Hoe said that Cisco had been taking a multi-pronged approach to finding areas of sales growth in software and services, by growing its security technologies while bolstering its Internet gear business.
"Others having been trying to follow us but without the inclusive strategy that Cisco has," Platon said. "Our viewpoint is comprehensive: it's desktops, it's servers, it's at the edge, it's at the core. Others are just beginning to join us on our path."
But Cisco is up against increasingly stiff competition that's willing to spend large amounts of capital in an effort to gain ground against the market leading company.
Last month, router vendor Juniper Networks bought NetScreen Technologies, a maker of firewalls and VPN technology in a deal valued at $US4 billion.
