1. Optional online diagnostics
A global switch allows WordPress.org checksum and plugin-directory queries, DNS checks, and self-tests of the site itself.
2. Vulnerability check
This is started separately by click and queries wpvulnerability.net with plugin identifiers. It does not require a Witte Marketing connection.
3. Witte Marketing services
External analysis, the detailed report, and monitoring are each started through their own actions and use the documented Witte Marketing endpoints.
Rule of thumb: Enabling one of these groups does not automatically enable the others.
