This is yet another example that shows us one can make money with open source software.
Network security specialist Sourcefire announced Friday that it has acquired ClamAV, an open-source gateway anti-malware project whose technologies are used in the products of a number of other vendors:
With nearly 1 million unique IP addresses downloading ClamAV malware updates daily across more than 120 mirrors in 38 countries, ClamAV is one of the most broadly adopted open source security projects worldwide. ClamAV has also been recognized as comparable in quality and coverage to leading commercial anti-virus solutions. Most recently, at LinuxWorld this year, ClamAV was one of only three anti-virus technologies to provide a 100% detection rate in their live 'Fight Club' test featuring live submissions from the show audience.
Sourcefire said that under the terms of the deal, it has purchased all of the project's technology and related trademarks, as well as the copyrights controlled by all developers involved in the effort, including its founder Tomasz Kojm.
