We're nothing if not diverse when it comes to the people and facilities we safeguard. We protect students in schools. Patients in hospitals. Guests in hotels. We protect transit workers in major hubs, staff in world-class museums and cutting-edge researchers working on the next big breakthrough.

Our technology portfolio integrates every aspect of a building – whether security systems, energy management, fire protection or HVAC – to ensure that we exceed customer expectations at all times.

We operate in more than 150 countries through our unmatched network of branches and distribution channels, helping building owners, operators, engineers and contractors enhance the full lifecycle of any facility.
