Committed to advancing professionalism in the field of security, the Society is organized on local, regional and international levels, in a global network of more than 180 Chapters.

ASIS members are charged with initiating and supervising loss-prevention programs to thwart internal and external offenses ranging from acts of terrorism, the pirating of classified documents, industrial/economic espionage, and counterfeiting, to insurance fraud, arson, employee theft, white collar, computer and organized crime. They are also responsible for preventing or minimizing losses from such natural or man-made disasters as fire, riots, strikes and other civil disorders.
