Established in 1967

MPS Security, a division of National Business Investigations, Inc. (NBI), is a multi-service security firm providing physical and asset security using Uniformed Security Officers and Executive Protection Agents for site security, events, residential and commercial properties, access control, patrols, loss prevention, fraud detection, and undercover roles.

In 1967, Ron Julian, a Navy veteran and former law enforcement officer, opened the first NBI office in Fullerton, CA, providing general investigative and protective services.

30 years later, Ron's son Michael Julian took the helm and established a separate division focused on protection, security, and risk mitigation services. MPS Protection & Security (MPS) was formed and became the organization's highest revenue-earning sector over the following decades.

Today, MPS serves clients throughout the U.S., including Fortune 100 companies, protecting their executives, assets, and reputation with a level of service refined by over 50 years of experience.
