As a comprehensive, multi-service protection firm, we deliver a best-in-class team of executive protection agents and uniformed officers for sites, high-profile events, estate coverage, corporate headquarters, as well as asset protection, patrols, loss prevention, and covert operations — all tailored to safeguard discerning clients.
MPS Security and Protection, a division of National Business Investigations, Inc. (NBI), provides elite uniformed and executive protection for critical assets—from corporate events to private estates. We specialize in access control, roving/vehicle patrol, fraud detection, loss prevention, and covert/undercover security operations.
Founded in 1967 by Navy veteran and former law enforcement officer Ron Julian, NBI pioneered comprehensive investigative and protective services from its original Fullerton, CA office.
Thirty years later, Michael Julian established a dedicated protection and risk mitigation division—MPS Security and Protection—which has grown into the organization’s leading revenue engine.
Today, MPS serves clients nationwide, including Fortune 100 firms, securing their executives, assets, and reputations with service grounded in five decades of expertise.
