In many states, they are licensed to carry firearms and often work in high-risk environments such as for VIPs, celebrities, or high-value assets. Their responsibilities include threat assessment, close protection, and emergency response. Level 4 Security guards typically require prior security experience and must meet specific state licensing requirements.

Strong situational awareness, leadership, and effective communication skills help you manage teams and diffuse high-stress situations. These competencies are crucial to ensure the safety of people and property, maintain compliance with regulations, and effectively handle emergencies.
