TE0019.1
Verification Service Gate
The human verification step came from a real verification service, such as Cloudflare Turnstile. These services are used to stop automated scanners, and passing the check says nothing about the page behind it.
TE0019.2
Simulated Verification Gate
The page showed a human verification step that only imitated a check, letting anyone through with a click. Attackers use fake checks to make a page look protected and trustworthy.
