The company was founded in 2000 when co-founders
Farnam Jahanian and Rob Malan spun out research from the
University of Michigan, sponsored by
DARPA,
Cisco, and
Intel. They were joined by students Jonathan Arnold, Matthew Smart, and Jonathan Poland, and entrepreneurs Ted Julian and Dug Song to make the founding team. The company raised $11 million in a round of
venture capital. Later, in August 2002, the company raised another $22 million in a second round of venture capital, led by
Thomas Weisel Venture Partners, with participants that included
Battery Ventures and
Cisco Systems, among others. In January 2008, Arbor acquired
Ellacoya Networks, a company which provides
broadband traffic shaping products. The acquisition was expected to increase the
total addressable market (TAM) for Arbor to $750 million in 2008, and to $1.5 billion by the end of 2009. In March 2009, Arbor worked with 100 ISPs to create a new network monitoring system, called ATLAS 2.0. In October 2009, the company estimated that
Google paid almost nothing for
YouTube's bandwidth, noting that Google probably used
dark fibre instead to run the website. On August 31, 2010,
Tektronix Communications announced that it has completed its acquisition of Arbor Networks. Upon completion of the acquisition, Arbor Networks joins
Danaher Corporation's portfolio of communications and enterprise companies, which includes Tektronix Communications. On September 3, 2013, Arbor Networks announced that it had acquired privately held Packetloop, a leader in Security Analytics based in Sydney, Australia. In 2015
NetScout Systems acquired Arbor along with
Fluke, Tektronix Communications (TekComms), and VSS, from Danaher. ==Company==
