Server signature checker
Server signature checker reads the Server response header for a URL. Inspect server information and understand how proxies can affect the reported value.
What is Server signature checker?
Server signature checker reads the Server header returned by a webpage request. It helps you inspect what server information a response exposes to clients. This can support a configuration review, but the value is a declaration from the response rather than proof of the complete hosting stack.
How to use this tool
Enter a page URL and submit the check. Review the reported signature, or the absence of one. Compare the same route after a supported hosting setting changes, and check representative pages if your application uses different servers or proxy rules for different paths.
Understanding the results
A CDN or reverse proxy can supply its own Server header, hiding or replacing the origin's value. The header can also be omitted or deliberately generalized. For that reason, do not treat it as reliable software inventory or assume that a reported product version identifies every component behind the website. The tool does not fingerprint services beyond the returned header.
Frequently asked questions
Does no signature mean the website is secure?
No. Reducing disclosed information does not establish that software is current or that vulnerabilities are absent. Use the result as one configuration observation.
Can I identify my hosting company from this value?
Sometimes the header gives a clue, but it may name a server product or an intermediary instead. Confirm hosting arrangements through your account records or a separate network lookup.
