The National Council of Investigative & Security Services is made up of security service and investigative agency owners and managers throughout the United States.  Regular membership is not offered to proprietary security management, in house investigators or foreign agency operators.

Most state's private investigator and contract security service associations are associate members of the NCISS and provide assistance and support when adverse federal legislation is proposed.

While the primary focus of the NCISS relates to monitoring federal legislation, training is provided at  annual seminars.

The president of Loss Prevention Concepts, Ltd. is a founding member and former Investigations Vice President of this organization.  He has served on the Board of Directors and chaired various committees.
