Explanation

The query is used to find the domains of URLs that were blocked. It includes two parts: one for Defender for Endpoint/Sentinel and another for EmailEvents. The first part filters UrlClickEvents data to find URLs that were blocked, extracts the domain and top-level domain (TLD) from the URL, and projects relevant fields. The second part filters EmailEvents data to find blocked emails with URLs or domains, joins with EmailUrlInfo data, extracts the domain and TLD from the URL, and projects relevant fields.
