What Auth0's website sends to your browser.
Scanned 2026-08-25. Grade headers B, scoring 80 out of 100.
This is one narrow, automated check of the HTTP response headers on the vendor's own website. It says nothing about how the product itself is built, how it stores your data, or whether it has ever been audited. A good grade here is a small signal that somebody was paying attention.
