From a Simple Spark to Global Security Leadership
Gallagher’s story began in 1938 in Hamilton, New Zealand, when founder Bill Gallagher Senior created the first electric fence to stop his horse, Joe, from damaging a car. That simple innovation sparked a global business.
More than 85 years later, Gallagher remains headquartered in Hamilton, with 1,300 employees worldwide working together to protect what matters most through advanced security solutions.
Today, Gallagher Security is a global leader in integrated technology, delivering trusted solutions across 140 countries. Its products—ranging from access control to perimeter and intruder detection—serve industries including government, healthcare, education, transport, and critical infrastructure.
Designed and manufactured at its global headquarters, Gallagher’s scalable systems help organizations stay safe, efficient, and productive. From securing high-risk sites to simplifying everyday operations, Gallagher empowers over 20,000 customers worldwide.
