Night clubs expert witness Bill Nesbitt is a Board Certified Protection Professional. On his website he answers the question:
Why is a security assessment (sometimes referred to as a security survey, vulnerability assessment, threat assessment, or security audit) so important?
Many security programs result from a series of reactions to perceived acute security breeches. Many of these kinds of programs resemble a patchwork quilt with no specific theme or mission. At some point, especially since 9/11, every business must establish a baseline from which to move forward into the future. There is a need to establish a foundational basis, at some point, for everything that is to follow. Those enterprises that fail to come to this conclusion usually have security programs that do not sufficiently produce adequate return on investment. A security assessment will allow the business to establish a foundation on which to build on for at least the next five years.
