Tumbleweed Communications today announced that its board of directors has unanimously named James P. Scullion as its new chief executive officer, effective immediately.

The move comes after Scullion was elected to serve as chairman of the board of directors on Jan. 9 after the resignation of Craig Brennan as CEO and chairman of the board.

Scullion has served on the Tumbleweed board of directors since April 2003, and has also chaired the company's audit committee. He brings almost 20 years of experience in the security arena to his new position. Most recently, he served as CEO and member of the board of directors of ComnetiX since January of 2004.

From 1990 to 2002, he held senior management positions with Identix Incorporated, a publicly traded biometric technology company. From 1996 to 2002, Scullion was responsible for all of the company's operations, first as executive vice president from 1996 to 1999 and then as president and chief operating officer from April 1999 to June 2002.

In addition, Scullion was a member of the Identix board of directors from 1998 to 2002 and previously was its chief financial officer from 1990 to 2001. Prior to joining Identix, Scullion served as chief financial officer at DataTrak, Inc. from 1986 to 1990.

Identix merged with Visionix in June 2002 and recently announced a merger with Viisage Technology, in a deal valued at $770 million.
