Questions
Does XML Sitemap Validator upload my input?
No. The working tool runs in the current browser tab. Avoid browser extensions or shared devices when handling sensitive material.
Does a passing result prove my system is secure?
No. It proves only the checks described on this page against the input you supplied. Server behaviour, business logic and runtime vulnerabilities require separate authorised testing.
Why is the result different from a live scanner?
This tool analyses pasted or local data. A live scanner observes network responses, DNS, TLS and redirects, so its evidence and scope are different.
