Loads scripts from

Third-party domains this page pulls JavaScript or iframes from. Each one can see who visits.

What to fix

1. Add Strict-Transport-Security
   Header: Strict-Transport-Security: max-age=31536000; includeSubDomains
2. Add a Content-Security-Policy
   Limits which scripts can run, and is the main defense against XSS. Start with Content-Security-Policy-Report-Only to test.
3. Add X-Content-Type-Options
   Header: X-Content-Type-Options: nosniff
4. Prevent clickjacking
   Header: X-Frame-Options: DENY (or a CSP frame-ancestors directive).
5. Add a Referrer-Policy
   Header: Referrer-Policy: strict-origin-when-cross-origin
