Security Investigator
Protecting assets and uncovering threats through vigilance and thorough investigation.
What is a Security Investigator?
Security Investigators work to prevent and investigate security breaches, theft, and other incidents within an organization. They conduct internal investigations, analyze security systems, and recommend improvements to safeguard assets and personnel. Their work helps maintain a safe and secure environment for employees and customers.
You spend days inspecting fire scenes, collecting and packaging fragments, photographing damage, and drafting detailed reports that trace evidence from scene to lab. Routine work includes acceptance testing of protection systems, following up on code violations, and subpoenaing and interviewing witnesses. Much of the role is office-bound paperwork and coordination with labs and prosecutors, punctuated by on-site evidence collection and testing.
