About

BSI Grundschutz++ OSCAL Viewer v1.6.54

A single-binary, offline viewer for the official BSI Grundschutz++ OSCAL catalog. The complete catalog is embedded in the executable: copy the binary, run it, and browse, filter and search every requirement — no installation and no network access required. The optional Annotations feature keeps your notes in a local SQLite file (--db); without it the viewer stays entirely read-only.
