Ferris started the company Frontline Security after being released from prison. In January 2004 Frontline Security were criticised when it was reported the company were guarding the Rosepark nursing home, where 14 pensioners had died in a fire. Relatives of the victims demanded to know why a company linked to Ferris had been hired. Three months later it emerged that Frontline Security had won a contract to protect speed cameras on the M8 motorway, with a police source stating "The fact this firm have been handed this speed camera contract is just plain ridiculous". Later the same year it emerged that the company had been paid taxpayers' money to protect Dumbarton Sheriff Court, and court bosses said they would not use the firm again.
