About MPS Security

In 1967, Ron Julian, a Navy veteran and former law enforcement officer, opened the first office of National Business Investigations in Fullerton, California providing general investigative and protective services.

30 years later, when Ron’s son Michael ascended into leadership of NBI, he created a separate division specifically focused on protection, security, and risk mitigation services. MPS Protection & Security (MPS) was born and continued to grow in the following three decades becoming the highest revenue earning sector of the organization.

Now in the 21st Century, MPS serves clients throughout the United States, including Fortune 100 companies, protecting their executives, assets, and reputation by providing a level of service derived from, and managed by, over 50 years of experience.
