Courses attended by the management include, although not limited to, Detective courses, Investigation of Crime, Law Policing and Human rights, Certified Fraud Examiners Course, Electronic Scene of Crime Course, Private Security Industry Regularity Authority Grade A Course, and more.

4N6 Have conducted numerous Risk Assessments at the premises of our clients in order to identify risks, as well as suggest remedies to be put in place, so as to mitigate the risks identified.

Furthermore we have been involved in conducting “Fraud and Corruption Awareness Sessions” to senior managers of our clients. This was to make senior management aware of the day to day risks that they are faced with during decision taking. This was conducted in conjunction with their “Business Code of Ethics” and included the UK bribery Act.
