Challenge we solve

How we solve Missing Referrer Policy

In our experience, A missing Referrer Policy means the server (or page) sends no directive controlling how much URL information is included in the Referer header when users navigate away from the page or load third party resources. Without an explicit policy, browsers use their own default (commonly strict origin when cross origin in modern browsers, but historically more permissive), which isn't guaranteed to match the site's privacy intent. This can leak full internal URLs, query parameters, or session adjacent data to external sites and analytics tools, an information disclosure risk rather than a functional bug.

How we solve Missing Referrer Policy

In our experience, A missing Referrer Policy means the server (or page) sends no directive controlling how much URL information is included in the Referer header when users navigate away from the page or load third party resources. Without an explicit policy, browsers use their own default (commonly strict origin when cross origin in modern browsers, but historically more permissive), which isn't guaranteed to match the site's privacy intent. This can leak full internal URLs, query parameters, or session adjacent data to external sites and analytics tools, an information disclosure risk rather than a functional bug.

Why this happens (and how we fix it)

In our experience, referrer Policy is a header that has to be explicitly set at the server or CDN level, and it's frequently skipped because the site functions identically whether it's present or not, so there's no functional bug forcing anyone to add it. Teams that haven't done a dedicated security header review are especially likely to be running on whatever their browser's own default happens to be rather than a policy chosen deliberately for their privacy needs.

What it costs you while it goes unfixed

In our experience, without an explicit policy, the amount of URL information leaked to external sites and analytics tools when a visitor navigates away is left up to browser defaults rather than a deliberate choice, which can expose full internal URLs, query parameters, or session adjacent values to third parties who receive that referrer data in their own server logs. For any page carrying sensitive parameters, an internal search term, an account reference, that's a verifiable information disclosure risk rather than a cosmetic gap.
