About Whelan Security

Founded in 1949 as a simple patrol company along the St. Louis riverfront, Whelan Security has enjoyed a rich heritage of service excellence rivaled by few in the contract security industry. While other security companies have merged, consolidated, downsized, or sold, Whelan Security is still owned by the same family and guided by the same business principles more than six decades after our inception.

Whelan provides contract security services across many diverse industries and vertical markets including corporate headquarters, commercial real estate properties, financial institutions, educational campuses, manufacturing & industrial facilities, retail shopping centers, residential communities, and sensitive government facilities throughout much of the United States. Driven by an employee-centric culture and a performance based business model, Whelan has grown to become one of the largest security companies in the country.
