Who we are

MPSI Security Inc. is a licensed Private Security Contractor in Illinois and Wisconsin and owns MPSI of Indiana.  We are currently waiting on issuance of our Florida license as well.


Unlike several security contractor agencies operating in these states, we live and work here, and the revenue and salaries generated by our corporation stay local.

With over 75 years’ of combined experience in Investigations, Law Enforcement, Medical, Military, and Security Services, MPSI is uniquely poised to bring highly qualified security management and security solutions to established, new, and growing businesses in every industry.

MPSI understands the unique nature of security concerns and vulnerabilities in the workplace, at special events, and even at personal residences and understand that our client’s concerns and needs may change at any time.  We specifically train our employees in the area of customer service and find that to be one of the most important attributes of our guards.  Our employees enhance security and safety at workplace, event, retail and residential environments.  Our goal is to focus on our client's needs and provide a customization security solution with our staff. 

MPSI prides itself in the ability to provide exceptionally professional and well trained guards. We specialize in uniformed and plain clothes guards, armed and unarmed as well as K-9 officers.  MPSI also provides executive protection agents who have acquired specialist training either through military or federal law enforcement training programs. 

MPSI Security is deeply committed to bringing the highest quality security solutions to your industry, helping to create a safe environment for the businesses, patrons and individuals on whom you depend. We operate on the principles of Honesty, Integrity, and Professionalism in order to achieve the highest levels of customer satisfaction.

We understand that our employees are an extension of our clients, as well as our company. We strive to achieve the highest level of professionalism through hiring select candidates who are dedicated, professional, hardworking and well trained. We will exceed your expectations due to our customer service satisfaction training and the personable approach of our entire staff.

MPSI Security is proud to say that we operate within all federal, state and local laws and regulations.
