HTTP and DNS callbacks

Introspector starts HTTP and DNS callback servers to register target’s interactions, a flag of the origin server’s country is shown to help interaction tracking. Introspector also has a whois button to show full information of the target.

Analysis and Detect SSRF Detection with controlled response delay

If you want to be sure about a backend’s interaction, you can use Introspector to set specific response time to a response.

Follow-Redirect Detection Redirect Chaining

If you want to know whether a backend behaves like a ‘browser-like’ client, Introspector can flag FOLLOW REDIRECT events when the target automatically follows 3xx responses and performs the next request (for example, when hitting common paths like favicon). This helps you confirm the system isn’t just validating a URL—it’s continuing the flow by following redirects.
