Challenge we solve
How we solve Mixed Passive Content
In our experience, mixed passive content is a subset of mixed content where only passive resources like images, audio, or video are loaded over HTTP on a HTTPS page, as opposed to scripts or stylesheets that can alter page behavior. It happens for the same reason as general mixed content, leftover absolute http:// references in markup or database fields after a HTTPS migration. Browsers usually still render passive mixed content but show a 'not fully secure' warning, which erodes user trust and can suppress the padlock/secure indicator in the address bar.

Why this happens (and how we fix it)
In our experience, this shows up for the same underlying reason as general mixed content, leftover http:// references in image src attributes, video sources, or audio embeds that never got updated during a HTTPS migration, but it's easier to miss because the page keeps functioning normally. Since passive resources don't execute code, they don't trigger the same hard warnings that active mixed content does, so these references can persist in a codebase for years without anyone noticing during routine QA.
What it costs you while it goes unfixed
In our experience, even though the page still renders, browsers show a 'not fully secure' or similar warning state and can suppress the padlock icon, which is a visible trust signal to any visitor who checks. For ecommerce or lead gen pages, that small dent in perceived security sits right at the moment a visitor is deciding whether to trust the site with a purchase or personal information, an unnecessary source of hesitation given how easy the underlying fix is.
