Twitter bans ads from Russia’s Kaspersky Lab

“We laid out a very transparent process and how we came to our decision,” to ban Kaspersky products from government networks, she said at a panel at the RSA security conference in San Francisco. “I would defer to the companies for how they made their decisions.”

Kaspersky said in an email that Twitter was the only social media company to ban its ads.

But other social media companies have taken action regarding Kaspersky Lab.

Facebook Inc in January said it had removed Kaspersky Lab from a list of anti-virus offerings to users.

When asked to explain its ban, Twitter said in an email, “This decision is based on our determination that Kaspersky Lab operates using a business model that inherently conflicts with acceptable Twitter Ads business practices.”

Twitter also said it was responding to a Department of Homeland Security warning of a threat to national security posed by Russian government access to Kaspersky products.

It is rare for Twitter to ban specific advertisers. In October it banned Russian media outlets Russia Today and Sputnik, accusing them of interfering in the 2016 U.S. elections. Last month, Twitter banned cryptocurrency ads.
