According to data from Forescout, which has been able to find banned devices via its government customers, there are at least 2,061 Dahua and Hikvision systems on U.S. federal government networks. That data was accurate as of August 19, and the figure is actually higher than the total from a July 11 scan, which stood at 1,797. But Forescout noted that the figure was higher only because it had gained more customers across government, not because agencies were buying more banned technology.
