“The risk that the Russian government, whether acting on its own or in collaboration with Kaspersky, could capitalize on access provided by Kaspersky products to compromise federal information and information systems directly implicates U.S. national security,” Ms. Duke said in a statement.
Kaspersky said it was disappointed with the Homeland Security’s decision and denied any ties to the Russian government.
“No credible evidence has been presented publicly by anyone or any organization as the accusations are based on false allegations and inaccurate assumptions, including claims about the impact of Russian regulations and policies on the company,” Kaspersky said in a statement.
Homeland Security officials say they will give Kaspersky an opportunity to submit written responses addressing the department’s concerns or efforts to address those concerns.
It is not clear how widespread the use of Kaspersky software is inside American government systems, which tend be a jumbled-together collection of often-aging software and hardware.
Kaspersky executives have repeatedly denied that the company has ties to any government and said it would not help Russia or any other government with cyberespionage, including Russia’s interference into last year’s presidential election. American officials have said that Russian hackers targeted the election systems in at least 21 states.
Kaspersky has figured elsewhere in the Russia-Trump saga.
Michael T. Flynn, President Trump’s former national security adviser was paid $11,250 by Kaspersky Government Security Solutions, an American branch of Kaspersky Lab, for a speaking engagement.
Despite its denials, the company has not been able to overcome American allegations about its ties to the Kremlin.
The Senate is voting this week on a defense-spending bill that would ban Kaspersky Lab products from being used by American government agencies. And Best Buy, the electronics giant, announced last week that it was pulling Kaspersky Lab’s cybersecurity products from its shelves and website.
Other technology companies have come under fire as investigators look into Russian election interference.
Suspected Russian operators used Twitter and Facebook to spread anti-Hillary Clinton messages during the campaign and to promote the hacked material they had leaked. Research at the cybersecurity firm FireEye found that on both social media platforms, Russian fingerprints are on hundreds or thousands of fake accounts that regularly posted anti-Clinton messages.
Many were automated Twitter accounts, called bots, researchers said, that fired off identical messages seconds apart. On Election Day, for instance, they found that one group of Twitter bots sent out the hashtag #WarAgainstDemocrats more than 1,700 times.
