Private Security Services

Physical Security Measures

The specific measures adopted can depend on the nature of your needs, the type of facility, and the perceived security risks. Our services are tailored specifically to what you need, and we’ll make sure to assess the entire situation before providing you with our recommendations and plan.

Surveillance Systems

On-site security often involves the use of surveillance cameras and monitoring systems to keep a watchful eye on the premises. Video footage can be used for real-time monitoring and investigations. Defender One can help you with installation providers as well as operating the equipment and surveilling footage, as needed.

Perimeter Security

Protecting the perimeter of a facility is essential. This may involve physical barriers, adding additional lighting, and supplying manpower for surveillance to deter and detect potential intruders.

Security Personnel

On-site security requires our trained guards to monitor and respond to security threats. Our team is available to conduct routine patrols, check identification at the entrances to buildings and floors, and provide a visible deterrent.

Intrusion Detection Systems

These systems are designed to detect and alert authorities to unauthorized entry or suspicious activities. This could include motion sensors, alarms, and other detection technologies.

Emergency Response

Our team designs emergency response plans and can also train your team on how to respond to emergencies, such as fires, natural disasters, security incidents, terrorist activity, and more. This is a crucial aspect of on-site security.
