Findings
-
Fail Security headers grade F SEC-HEADERS-GRADE
15 / 100: almost no browser protections are declared.
How to fix: Start with Strict-Transport-Security and X-Content-Type-Options, then add a Content-Security-Policy in report-only mode.
-
Caution Plain HTTP serves content instead of redirecting to HTTPS WEB-HTTP-NO-REDIRECT
How to fix: Redirect http:// to https:// with a 301.
-
Caution No HTTP Strict Transport Security header HSTS-MISSING
Browsers may still try plain HTTP first on each visit.
How to fix: Send "Strict-Transport-Security: max-age=31536000; includeSubDomains".
