Arbor Networks Acquisition Is a Tale of Two Cities—and a Strategic Move Into Wider World of Wireless

provider has used Arbor’s software to keep things running smoothly.)

Jahanian and Malan’s team raised a Series A venture round in 2000, led by Battery Ventures and Cisco Systems, and then a Series B round in 2002, led by Thomas Weisel Venture Partners. Those two rounds, the only outside funding taken by the company, were worth about $33 million. (Because the Danaher acquisition price hasn’t been disclosed—and Arbor’s leaders kept their poker faces on, giving me no indication of the size of the financial win—it’s hard to know yet how well the investors made out.)

In its early days, Arbor made an important decision: to put the company’s headquarters in the Boston area while keeping the core engineering team in Ann Arbor. “We knew we could build a phenomenal R&D team in Ann Arbor,” Jahanian says. “But to recruit the quality of executives [we wanted], we had to be either on the East or West Coast.” The combination of Battery Ventures being in the Boston area, the strong local business talent, and proximity to the East Coast’s big wireless carriers and Internet service providers swung the decision in Boston’s favor, he says.

Arbor worked its way deep into the market over the next few years, becoming profitable relatively quickly. It wasn’t easy. Network security, starting around 2000, was one of the most crowded and contested fields in all of IT, full of competitors like Riverbed Technology, Lancope, Mazu Networks, and Asta Networks, as well as big companies like IBM. From what I hear, it’s pretty amazing that Arbor (or anyone for that matter) survived this hostile sector.

    “full of competitors like Riverbed Technology, Lancope, Mazu Networks, and Asta Networks”. You probably mean “Riverhead” and not “Riverbed”

  • Jason, thanks for pointing this out. Actually I did mean Riverbed, which acquired Mazu fairly recently to compete better with Cisco. But yes, Riverhead Networks was a closer competitor to Arbor, focused on distributed denial-of-service attacks, and Cisco bought it back in 2004.
