Challenge we solve
How we solve Missing Feature Policy
In our experience, A missing Feature Policy (now largely superseded by the Permissions Policy header) means the site sends no header restricting which browser features, like camera, microphone, geolocation, or autoplay, can be used by the page or its embedded iframes. It happens because the header is opt in and easy to overlook since its absence doesn't break functionality. Without it, third party scripts or embedded content have unrestricted access to sensitive browser APIs, widening the attack surface for privacy invasive or malicious embedded code.

Why this happens (and how we fix it)
In our experience, feature Policy (and its successor, Permissions Policy) is a header that has to be explicitly configured to restrict browser APIs like camera, microphone, and geolocation, and because the site works identically with or without it, there's no functional pressure to ever add it. It typically gets skipped for the same reason many security headers do, it requires someone to audit every embedded iframe and script to decide what should be restricted, and that audit rarely gets prioritized over feature work.
What it costs you while it goes unfixed
In our experience, without a restrictive policy, any third party script or embedded iframe on the page, an ad, a widget, an analytics tag, has unrestricted access to sensitive browser APIs by default, so a single compromised or poorly vetted embed can attempt to access a visitor's camera, microphone, or location without an extra layer of browser level enforcement standing in the way. It's a defense in depth gap, not the first thing an attacker needs, but one less barrier standing between a vulnerable embed and verifiable privacy harm to visitors.
