The FBI presentation said part of the problem lies with government procurement practices, revealing that the government normally searches for the lowest prices for products. A counterfeit Cisco 1721 router costs $234 (£120), while the genuine version costs approximately $1,375. Another part of the problem is that government contracts allow for several levels of sub-contractors and non-OEM purchases, according to the presentation. The FBI said there was little or no vetting of vendors or partners by the organisations. It was "gold" and "silver" Cisco partners who had been selling the counterfeit products to the government, said the FBI. Cisco on Tuesday admitted that some of its partners had sold counterfeit goods but said the majority of its certified channel partners had not sold counterfeit Cisco products. The company instead blamed the "grey market" of semi-legal deals for most of the problems.
