Security System Service

The world is changing and so are security risks. That’s why we are always investing in our security systems to ensure that we meet our customers' expectations and needs, even as the type and severity of security risks evolve. This means always keeping up with new and innovative security technology developments.

Additional Security Services

G4S also provides security guard services, as well as risk management security services. Visit our other services pages for more details.


At the core of our operations is the ability to combine the best of our people, risk, technology and data services. We do this through transparency and a coordinated approach to serve our customers with end-to-end, flexible, and scalable technology driven integrated security solutions.

Individualised Support
Our customer service model is based around individual customer support. Our customer service is integral in our day-to-day operations, in whatever capacity our customers may need our support. For more than 100 years, our strength as a company has been our dedication to building strong customer relationships and we have continued to foster these partnerships.
Geographical Reach
Each of our offices is locally and independently managed, with the added benefits of the resources of a global organisation. Our local management is tied to the community, builds lasting relationships with their customers, and is built with professionals that have devoted their careers to the provision of quality security services.
Our size and scale allow us to bring our customers benefits that smaller providers may not. We are able to push the industry forward with innovative technologies and a flexible emergency response offering.
