Greenroom Security Agency staffs, manages, and protects Chicago's highest-profile events — pairing seasoned command leadership with the next generation of safety technology. From 300 to 25,000+ attendees a day, with a zero-incident record.
From festival gates to full-venue command, this is how our team keeps Chicago's biggest events safe.
One partner for the entire safety operation — planning, personnel, command, and compliance — delivered under ASIS International, NIMS, ICS, and FEMA Whole-Community standards.
Trained, professional unarmed event personnel — from intimate galas to multi-day festivals serving tens of thousands daily.
Ingress/egress strategy, credentialing, perimeter security, and crowd-flow optimization that keeps lines moving and guests safe.
EAPs and risk assessments aligned to CISA and NCS4 guidelines for venues, amphitheaters, restaurants, and festivals.
Unified ICS/NIMS command structures and multi-agency coordination with police, fire, EMS, and OEMC.
Close protection for executives, talent, and field news reporters operating in high-pressure environments.
Visible, professional patrol presence for residential and commercial properties and community partners.
Personnel will always be the core of safe events. But the best outcomes come when trained teams are amplified by technology — extending what a human can see, hear, and respond to. That's the direction Greenroom is built to grow into.
Real-time visibility into crowd build-up at gates, stages, and choke points — so teams move before a bottleneck becomes a problem.
Integrated screening at ingress points for fast, non-intrusive entry security.
Real-time event communication and coordinated incident response across the venue.
Primary security force for DCASE events including the Taste of Chicago and the Chicago Air & Water Show — plus the Special Olympics, the Chicago Park District, and dozens of high-profile producers across Illinois.
Greenroom consistently went above and beyond — often with short notice. Their staff is outgoing, keeps a positive attitude, and regularly identifies and resolves security issues before we even know there's an issue.
Your crew was amazing — every team member was on it. Any incidents were handled immediately and with the utmost professionalism. I gladly recommend them to any organization seeking a dependable security partner.
Founded and led by Eugene Posey — Founder & Director of Security, and an 18-year Chicago Police Department veteran with an MPA in Public Safety Administration.
