The Department of Homeland Security issued the order on September 13 following growing criticism in Congress and elsewhere about the Moscow-based company’s software products, which are widely used in the United States and elsewhere, RFE/RL reports.

A statement said executive-branch departments and agencies have up to 90 days to begin discontinuing use of Kaspersky software and remove the products from computer systems.

“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,” the agency said.

Company founder Eugene Kaspersky has for years been under scrutiny both for his early education at a KGB-run school, but also because of suspicions that the company has the quiet backing of Russian security agencies, like the Federal Security Service (FSB).

Kaspersky has long denied that his company, one of Russia’s most successful technology companies, has connections to Russian intelligence agencies.

In a statement, the Russian company again denied the accusations, saying there is "no credible evidence" to back up the claims, including the allegations of Russian government ties.

"Kaspersky Lab has never helped, nor will help, any government in the world with its cyberespionage or offensive cyberefforts, and it's disconcerting that a private company can be considered guilty until proven innocent, due to geopolitical issues," it said.
