US intelligence officials are expressing concern over a Russian cybersecurity company’s access to US government systems and pushing the Government Services Administration for answers on how long it has been approved for use by US agencies.

Three US intelligence officials told BuzzFeed News they were concerned by what they categorized as a close relationship between the company, Kaspersky, and the Russian government, and what giving the company access to US government systems could mean. All of the officials who spoke with BuzzFeed News requested anonymity to discuss internal intelligence community conversations about Kaspersky.

A spokesperson for Kaspersky told BuzzFeed News that the company “has no ties to any government, and the company has never helped, nor will help, any government in the world with its cyberespionage efforts. For 20 years, Kaspersky Lab has been focused on protecting people and organizations from cyberthreats, and its headquarters’ location doesn’t change that mission–just as a U.S.-based cybersecurity company doesn’t send or allow access to any sensitive data from its products to the U.S. government, Kaspersky Lab products also do not allow any access or provide any secret data to any country’s government.”
