A Cut Above other security GUARD SERVICES… CHICAGO security experts who give back

The Always Giving Back Foundation is the charitable and philanthropic arm of AGB Investigative. Our security company, AGB, was crafted intentionally to stand for Always Giving Back. While cyber security and security guard service are our craft, bridging the diversity gap for minorities is our ministry. This is why our mission has always been to provide business and security training and create hundreds of professional opportunities for adults, both within and beyond the security industry, and particularly within the most underserved areas of Chicago.
