One would hope and expect that when selecting private security services providers, buyers would base themselves primarily on quality criteria, and not just cost. Regretfully, this is rarely the case.
ASSA-i and CoESS, the Confederation of European Security Services have been recommending guiding principles and quality criteria for the selection of quality private security services.
Back in 1999 already, CoESS published a first version of their Best Value Manual. In 2015 a new version was developed, in cooperation with
UNI Europa, and financial support of the European Commission.
The new guide, entitled “Buying Quality Private Security Services”, is available in 14 languages, and can be downloaded here: http://www.securebestvalue.org
