Key notes

Firstly, HTTP security header not detected is an alarming issue that leaves your site vulnerable to hackers. Security headers determine whether a set of security precautions should be blocked or activated on the web browser.

Security headers direct and instruct web applications on how to handle your request and rely on responses from HTTP headers.

It depends on the responses obtained from the metadata in the HTTP request to determine if the HTTP security header is not detected.

Also, new browsers have a built-in protection system known as the XSS filter. However, it could be turned off by default, which leads to this problem.
