About MPS Security

Established in 1967

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

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 the 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.

    I've worked for many security companies, and I enjoyed this one the most because they were organized and didn't micromanage. Tally Flotron is great! She is by the books, but always helpful and fair.
