In May 2004, Trend Micro, a competing cyber security and defense company, filed a legal complaint against Fortinet. Though the International Trade Commission initially ruled against Fortinet, the Trend Micro patents at the center of the dispute were later declared as invalid in 2010. In 2005, an OpenNet study suggested that Myanmar, which was under American sanctions, had begun using Fortinet's FortiGuard system for internet censorship. Fortinet stated that their products are sold by third party resellers, and that they acknowledged US embargoes.
