The distinction between a security guard and a private investigator is primarily based on their roles and responsibilities. Security guards are primarily responsible for the protection of property and individuals. Their duties often include monitoring premises, preventing unauthorized access, patrolling areas to deter crime, and responding to incidents to ensure safety and security.

In contrast, private investigators are trained to conduct investigations. Their work involves gathering information, conducting surveillance, and performing background checks for various purposes, such as legal cases, security issues, or personal matters. They often deal with specific inquiries and uncover details that are not related to immediate protective measures or security responses.

This difference in focus defines the two professions distinctly, emphasizing that while both contribute to safety and security, their methodologies and objectives vary significantly. The other options misinterpret or oversimplify these professional roles, failing to recognize the unique functions and purposes each serves in the field of security and investigation.
