Citrix is losing its sales boss John Burris to one of the open source contingent’s few publicly traded companies, the struggling Sourcefire, creator of Snort, the security software, whose $15 IPO price has pretty been shaved in half since its debut in March of 2007.

Burris will replace Wayne Jackson who is leaving though he will remain on the board.

Barracuda Networks made an unsolicited $188 million bid for Sourcefire last month and was told the offer substantially undervalues the company.

Burris was instrumental in getting Citrix from $470 million to $1.4 billion. Sourcefire lost $6.5 million on $55.9 million in sales last year. He takes over July 14.

Burris joined the Sourcefire board on March.
