ST. PAUL, Minn. And SAN FRANCISCO - November 15, 2007- Nagios
Enterprises (www.nagios.com <http://www.nagios.com/> ), the commercial
arm of Nagios, the world's most popular open source host, service and

the leader in open source IT management software, today announced a
joint partnership focused on joint market development and shared
delivery of services around open source IT monitoring and management.

"Nagios Enterprises is pleased to collaborate with GroundWork Open
Source,"
said Nagios creator and lead developer Ethan Galstad. "Over the past 18
months, GroundWork has done some great things with Nagios in developing
a comprehensive IT management solution, and Nagios Enterprises can now
extend the joint value further with the new formalized working
relationship."

Under the terms of the joint partnership, Nagios Enterprises will soon

monitoring, while others are focused on broader system management," said
Ranga Rangachari, CEO of GroundWork Open Source. "Partnering like this
allows each party to focus on their core competencies for the best time
to value, namely, monitoring and broad system management and
integration."
