Status: NetBox: 4.5–4.6 · Plugin: 0.4.17 · Requires: netbox-custom-objects
Features
- Security Panel on prefix, IP, device, VM, custom objects —
+ Assignfor zones, addresses, … - Bundles — deploy NSM schema and demo data from JSON bundles (
Security → Configuration → Bundles) - Type Metadata — per-COT settings (
nsm_configin type comments): role, display template, sort order - Rulebooks with flexible columns (zones, addresses, labels, …)
- Rules — table, row grouping, grouped columns, zone matrix; Export JSON (bundle-compatible, re-import via Bundles)
- IP Analyzer — address resolution via the IP Analyzer applet on rule pages (loupe icon)
- Object Analyzer — graph from any NetBox object
- Object Report — daily background audit of NSM addresses/groups; TOML export

Bundles — apply nsm_schema first, then optional demo bundles:
Type Metadata — nsm_config per COT type (role, display template, sort order):
Object Report — daily address/group audit with TOML export:
Rulebooks — list and detail (fields, enforcement targets):
Rules — row grouping, grouped columns, Export JSON:
Zone matrix — permit/deny between zones:
IP Analyzer — destination tree with merge/diff:

First run
- Security → Configuration → Bundles — Apply
nsm_schema(required; imports built-innsm_*COT types and writesnsm_configinto each type's comments). - Optional demo bundles: RB Demo Zone Matrix, RB Demo Zone/Address (Preview → Apply).
- Open a prefix → Security tab →
+ Assign→ zone. - Rulebooks under Security → Rulebooks.

Rules export / import
On a rulebook Rules tab, Export JSON downloads all rules matching the current filters (not just the visible page) as a bundle-compatible JSON document (objects[].records[] with portable refs like nsm_zone/zone_01). Import the file via Security → Configuration → Bundles (objects seeding).
