Armed security refers to security personnel who are equipped with firearms for the purpose of protecting individuals, properties, and assets. These individuals are typically trained in the use of firearms and the handling of weapons, and they may have the authority to use force if necessary. Armed security is often used in high-risk situations, such as for protecting high-value assets or during volatile events.

Unarmed security refers to security personnel who do not carry firearms. Instead, they may use other tools, such as pepper spray or batons, for self-defense. Unarmed security personnel are typically used for tasks such as crowd control, surveillance, and access control. The goal of unarmed security is to provide a visible security presence, deter criminal activity, and respond to security incidents as necessary.
