Is hsprotect.net a Microsoft property? Graph authentication

Running connect-mggraph, I get the IE "Sign in to your account/Verify your identity" windows.

The first time through, it presents several of the "Trusted Sites" dialogs, to add various MS URLs to the trusted zone.

One of them is https://iframe.hsprotect.net.

The WHOIS for this domain does not list Microsoft. It's NameCheap, with "withheld for privacy" addresses in Iceland.

Microsoft does not document this domain anywhere, though A.I. claims/hallucinates that MS uses it for protection-related telemetry and is certain it's in the Defender API guide.

Can anyone confirm what's going on here?

  • Hope im not too late, but its PerimeterX / Human captcha, the captcha used by microsoft on signup and some other account related things like adding a phone number for the abuse prompt. Its a replacement for funcaptcha/arkose, but arkose is still used sometimes if your IP score is good
