GhostHunter is a Chrome add-on developed by greaselovely, designed to assist web administrators and security professionals in tracking and logging domain requests for specific tabs. In the modern web landscape, managing the numerous Fully Qualified Domain Names (FQDNs) associated with websites, especially those utilizing SaaS applications, can be challenging. GhostHunter aims to simplify this process by allowing users to effortlessly capture and catalog these FQDNs and their corresponding referrers.

By providing visibility into the complete network of FQDNs used by a website, GhostHunter empowers administrators to make informed decisions regarding access control and resource allocation. This tool is particularly useful in environments where strict security measures are required, enabling administrators to enforce policies that restrict access to essential domains only, thereby enhancing web security.
