What is the difference between a "security guard" and a "private investigator"?

The distinction between a security guard and a private investigator lies primarily in their roles and responsibilities. A security guard's main function is to protect property, individuals, and assets by monitoring environments, enforcing rules, and responding to emergencies. Their focus is primarily on maintaining safety and security in specific locations, such as offices, schools, or events.

In contrast, a private investigator typically conducts investigations, which may include gathering evidence, conducting interviews, and analyzing information to help their clients address specific issues, such as fraud, missing persons, or legal matters. The nature of their work often requires them to utilize research and observational skills rather than the enforcement of laws or security protocols.

This clear differentiation highlights the roles each professional plays, with the security guard's main focus on protection and the private investigator's emphasis on investigative work.
