ISIG

ISIG is an acronym used to refer to multiple, unrelated entities and concepts. It does not designate a single organization, standard, or term; the intended meaning depends on the context, geography, and field of reference. In reference works, ISIG entries typically begin by noting that the abbreviation has multiple meanings and then outline the relevant expansions for different domains.

In government and public administration, ISIG is often encountered as shorthand for interagency groups or institutes that focus on information handling, security policy, or collaborative governance. In the sciences and engineering, ISIG may appear as a domain-specific acronym within a particular discipline, standing for terms defined within that field. Because there is no universally accepted expansion, readers should rely on contextual cues such as accompanying organization names, field descriptors, or other related acronyms to identify the precise reference.

If you have a specific sector or region in mind, providing that information can help determine the most probable ISIG meaning and allow for a more targeted, domain-focused description.
