Security Services

On Site Security

Our on-site security services refer to the measures and practices implemented to protect physical spaces, properties, and assets from unauthorized access, vandalism, theft, or other security threats. This type of security is primarily focused on safeguarding a specific location, such as a building, facility, or campus.

Executive Protection

High-profile individuals, such as business leaders, celebrities, and sports personalities, hold significant value for the organizations they represent. Their public visibility exposes them, and their families, to potential threats. To ensure their safety, these VIPs require specialized and highly trained protection services.

Specialized Security

Defender One Security works with medical institutions, private schools, daycare facilities, corporations, and residential communities to offer customized security solutions. Our security teams are well-versed in the latest security methodologies, guaranteeing that our clients receive the most effective protection possible. Specialized services may include tactical units, vehicle patrols, law enforcement personnel, and more.

Private Investigation

Private investigation is an indispensable resource for providing vital information to support critical decisions, protect assets, and mitigate risks.

We offer private investigators to verify insurance claims, investigate employee misconduct, track spouses, investigate domestic violence situations, and more.
