A unit of telecommunications giant Verizon agreed to pay approximately $4.1 million to settle allegations levied by the Department of Justice (DOJ) regarding false claims caused by failure to fully implement cybersecurity controls required of a government contractor.

Verizon Business Network Services violated the False Claims Act when it “failed to completely satisfy certain cybersecurity controls in connection with an information technology service provided to federal agencies,” the DOJ said in a press release Tuesday.
