Security headers
Domain & Security TechnicalYour site sends 1 of the 5 security headers we look for; missing: csp, x_frame_options, x_content_type_options, referrer_policy.
Why it matters: These headers tell browsers how to protect visitors - for example, stopping your pages being framed inside someone else's site.
How to fix it: Ask your developer or host to add the missing headers in the server or hosting settings.
