"I'm pleased to welcome American Security to the Allied Universal team. The transition will be seamless as American Security and Allied Universal share a deep commitment to our employees, as well as our customers and the communities we serve," said Steve Jones, Global Chairman & CEO of Allied Universal.

"I am also excited that several members of the American Security management team will join Allied Universal to coordinate a seamless transition," Jones said.

We will be able to take the service we provide to our clients to the next level, and our employees will have access to growth opportunities throughout the world because Allied Universal has a promote-from-within culture."
