As an independent company

Arbor Networks is a computer network security firm headquartered in Chelmsford, MA, but with a sizable presence in Ann Arbor - 72 employees at the beginning of 2008. The office is currently out on South State St, just north of the 777 Building. This building houses Arbor Networks' engineering teams. The Arbor Networks office used to be in the center of Ann Arbor, on the 2nd and 6th floors of the City Center building. Before that, it was on the top floor corner of State Street and Liberty Street, above what used to be Gratzi, and is now Starbucks.

On January 22, 2008, the Michigan Economic Growth Authority awarded Arbor Networks a 10-year, $1.5 million tax credit package as part of a deal for Arbor Networks to expand in Ann Arbor rather than Boston. The expansion would involve 56 new jobs and $14 million in investment in a Michigan site over the next few years - but that site may not be in downtown Ann Arbor, based on lack of available office space for the growing company.

Arbor Networks was founded in 2000 as a spinoff from University of Michigan research conducted under a DARPA grant.

Number of employees: approx 160, approx 60 in Ann Arbor office
