How it works

01

Start with a domain or IP

Run a full scan when you are not sure where the issue sits, or choose a record-specific check when you already know the problem area.

02

Read the key findings first

The workspace leads with the highest-signal conclusions so mixed technical and non-technical users can orient themselves quickly.

03

Expand into details only when needed

Tabs keep records, propagation, health, registration, and developer payloads available without crowding the default view.
