There are plenty of publicly traded large security companies. They may not be the absolute best, but they're not going to screw you over. I would feel pretty comfortable calling G4S, Securitas, GardaWorld, DynCorp, Brinks, Control Risks, etc. Alternative, you call the whitest of white shoe law firms and retain them to find a good security firm for you.
