Bouncers, also known as security personnel or door supervisors, are individuals hired to maintain security and control access to premises, such as nightclubs, bars, and event venues. They are responsible for ensuring the safety of patrons and preventing incidents such as fights, theft, or other forms of disorderly behavior.

Bodyguards, on the other hand, are individuals hired to provide personal protection for a specific individual or group of individuals. They are often used to protect high-profile individuals, such as politicians, celebrities, or business executives, and may accompany them to events, meetings, and other public appearances. Bodyguards are trained in a variety of security techniques, including evasive driving, self-defense, and emergency response procedures.
