Our story

Founded in 2010, built on specialist delivery

Founded in 2010, Global Support Services was built to answer a real market need: adaptive and progressive security, delivered with an unsurpassed attention to local detail. Not off-the-shelf guarding, but specialist canine, close protection, and surveillance capability matched precisely to each client's risk.

We keep improving our people, systems, training and technology, so the service clients receive keeps getting better. A UK-wide network of trained professionals lets us respond quickly, wherever the work is.

Our clients will always benefit from cutting-edge service delivery.
