After conducting a thorough safety and legitimacy analysis, 91quanbao.com receives a trust score of 53/100, which places it in the "Caution Advised" category.

The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks.
