SOS Security started out by serving clients in New Jersey, and from these local beginnings, followed clients all over the U.S. and the world. Now the fifth largest security personnel company in the U.S., SOS Security’s growth is driven by our ongoing dedication to meet our clients’ evolving security requirements. As these needs have expanded and changed, so has the scope and character of our growing portfolio of security solutions – both through controlled organic growth and carefully executed strategic acquisitions.
