Kaspersky Lab is fighting back against the Trump administration’s ban of its security products in agency networks with a lawsuit filed today. The Moscow-based security company is seeking the appeal of US Department of Homeland Security’s September 13 Binding Operational Directive 17-01 that banned federal agencies from using its products on their systems. DHS cited its concerns of Russian law requiring companies to cooperate with its intelligence agencies. The DHS ban came in the wake of concerns about potential ties between officials at the firm and Russian intelligence agenices, and required federal agencies to remove it.”]
