This book is about crossing the very real line that separates the worlds of public and private security and risk management. It is a guide for key players who are thinking of switching sectors and roles and moving from one kind of organization and operating culture to another often significantly different one. It is principally aimed at people who are seeking to play a senior role, with significant responsibilities for corporate security or other forms of risk management and mitigation, in a new environment, and where strong leadership skills will be a major advantage to meeting personal and organization objectives. It is particularly relevant for those moving within senior levels of expertise, especially where enterprise-wide skills will be required, yet there are lessons for all potential movers and for those challenged with finding and keeping outstanding talent.
