In this environment, a new industry has grown to deal with these challenges: international security consulting. Drawing from military, law-enforcement, and intelligence communities, new private companies are springing up across the world. Global Security Consulting, written by a former intelligence specialist who has built a successful consultancy, provides solid guidance for anyone wishing to enter this glamorous but often dangerous field.
