I was invited to attend the covert surveillance and osint level 3 courses by Jason at ESS Consulting. I have a background in government intelligence services and therefore a grounding on covert operations.
My honest assessment of the surveillance training, although being relatively short in duration (5 days) is all around excellence. The techniques and case files this company impart and the work they’ve been involved with could have come straight out of a spy novel. Some ingenious methods of achieving remarkable results and the instructors are first class.
My verdict, great training by a very competent operational company.
