Three months after the General Services Administration removed Kaspersky Lab from a list of approved federal vendors, Homeland Security is banning the Russian security software maker outright. In a statement on Wednesday, DHS Acting Secretary Elaine Duke directed all Executive Branch agencies and departments to identify any Kaspersky products being used over the next 30 days, to make a plan to eliminate their use in the next 60 days and to begin that discontinuation within 90 days.

“The Department is concerned about the ties between certain Kaspersky officials and Russian intelligence and other government agencies, and requirements under Russian law that allow Russian intelligence agencies to request or compel assistance from Kaspersky and to intercept communications transiting Russian networks,” DHS said in its directive.
