The National Institute of Standards and Technology (NIST) is the United State's equivalent of the International Organization for Standardization (ISO).
Originally, NIST 800-53 only applied to Government entities, but the latest revision of NIST 800-53 (revision 5) extends the framework to non-U.S Government.
This revised version accommodates the unification of different security controls to facilitate the integration of multiple cybersecurity frameworks.
