Finjan Holdings, a cyber-security company, has appointed Gary Moore to its board of directors.

Moore served most recently as president and chief operating officer of Cisco Systems, a position he held since 2012. He joined Cisco in 2001 as the senior vice president of the Advanced Services Division. He currently lectures at The Ohio State University Fisher School of Business as an executive in residence.

He will fill a vacancy on Finjan’s board that was created following the resignation of Michael Eisenberg, a general partner at Benchmark Capital and now partner of Aleph, a Tel Aviv based early-stage venture fund. Eisenberg has been a director of Finjan Holdings since it became a public company in June 2013 and an investor of Finjan’s subsidiary, Finjan, Inc. since 2003.
