Let's check how your browser is set up.

What this checkup does and doesn't do: everything above is based on information your browser voluntarily shares with any website it visits — connection type, browser/OS version signals, and a couple of standard web APIs. It cannot see installed apps, scan for malware, check for unpatched operating-system vulnerabilities, or inspect your network beyond what's described above — no website can, by design of how browsers sandbox pages from the rest of your device. Treat the score as a quick hygiene check, not a full security audit.
