Brosnan Security® Officers are consistently ranked as the best in the industry. 

Before acceptance into the Brosnan Institute™ training program, potential security recruits undergo a rigorous background check. Upon completion of the program, new security officers are assigned to posts based on experience, location-specific training and client requirements.

Whether you require a Personal Armed Bodyguard to escort you to your next high profile event or a highly trained Security Guard Team to protect your commercial property, we have you covered and can configure our advanced security teams and systems to meet your specific needs. All of our Security Guards are licensed in the states they do business in and trained in first aid and CPR.


To properly anticipate and manage an emergency or disaster response, clients need a field-tested partner that can provide detailed risk assessments, proactive security technologies, experienced security personnel and real-time intelligence. Brosnan️'s team of disaster response specialists prepare and implement emergency action plans for terrorism, manmade disasters, social unrest, riots, active shooters, disease outbreaks and other threat events.

COVID-19 has been a harsh reminder that some of the greatest threats we face cannot be immediately resolved. Mitigating these threats requires changes in social behavior and implementation of enhanced safety protocols. Achieving that goal requires specialists that only Brosnan can provide. Brosnan’s response to the COVID-19 pandemic is led by former CIA and military infectious disease experts. Using guidance established in part by the Centers for Disease Control, Brosnan has created screening and security protocols that ensure employee and customer compliance with your company’s safety policies, including any federal, state and local laws.


Brosnan’s Construction-to-Occupancy Security Program (C2O) is the security industry’s only comprehensive security solution for commercial construction projects.  The program begins with a security assessment of the construction site and recommendations for a layered security program that evolves and progresses as the site evolves and progresses.  This innovative program is the industry’s only full circle, end-to-end solution that ensures continuity from the time the first shovel breaks ground until the day that the new property's tenants occupy their spaces.
