Mixed Content

Mixed content occurs when HTTPS pages load resources (scripts, images, etc.) over insecure HTTP.

Why It Matters

Mixed content undermines HTTPS security. Active mixed content (scripts) is blocked by browsers. Passive mixed content (images) shows warnings and can be modified by attackers.

How We Check

We scan your page for resources loaded over HTTP and identify active vs passive mixed content issues.

How to Fix

Update all resource URLs to use HTTPS. Use protocol-relative URLs (//) or absolute HTTPS URLs. Add CSP upgrade-insecure-requests directive.
