DansGuardian
content-control software
DansGuardian, written by SmoothWall Ltd and others, is content-control software: software designed to control which websites users can access. It also includes virus filtering and usage monitoring features. DansGuardian must be installed on a Unix or Linux computer, such as a server computer; its filtering extends to all computers in an organization, including Windows and Macintosh computers. DansGuardian is used by schools, businesses, value-added Internet service providers, and others.
As of now, DansGuardian is no longer maintained. Its successor is named "e2guardian".

Begin with the source’s own compact description: “DansGuardian” is content-control software. The dossier treats that line as a proposition to test through DansGuardian, content-control and software, not as a finished interpretation.
Why this record matters
The phrase “content-control software” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 11, 2025. The linked authority identifier is Q524566. None of the 1 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
