Google announced to its employees that it would be banning them from using Zoom on their company computers because of potential security vulnerabilities.

“We have long had a policy of not allowing employees to use unapproved apps for work that are outside of our corporate network,” Jose Castaneda, a Google spokesperson, said in a statement to Buzzfeed News on Wednesday. “Recently, our security team informed employees using Zoom Desktop Client that it will no longer run on corporate computers as it does not meet our security standards for apps used by our employees. Employees who have been using Zoom to stay in touch with family and friends can continue to do so through a web browser or via mobile.”
