Who is liable if an assault occurred because a third-party security guard failed to do their job?

Both the property owner and the hired security company may be held legally responsible. In Florida, property owners owe a duty to keep their premises reasonably safe for lawful visitors, which cannot simply be discharged by hiring a contractor. Additionally, private security companies can be sued directly if their guards act negligently—such as abandoning posts, failing to monitor cameras, or lacking proper training under Florida regulations. The Altman Law Firm evaluates vendor contracts, guard logs, and post orders to identify all negligent commercial parties after an injury occurs.
