0–100, higher is better. How it is calculated

抵押车交易网 is a Chinese online platform specializing in the buying and selling of mortgage vehicles across China. Established in 2014 and operated by Chengdu Fly-Digital Technology Co., Ltd., it offers a marketplace with vehicle listings, price evaluations, and customer support services. The platform targets consumers and businesses interested in secure and regulated mortgage vehicle transactions. The website features a professional design with clear navigation and localized city-based filtering to enhance user experience. Technically, the site employs common JavaScript libraries such as jQuery and Swiper.js, integrates Baidu and Ahrefs analytics, and hosts images on Alibaba Cloud OSS. While HTTPS is enforced, the site lacks advanced security headers and DNSSEC, which are recommended for improved security. Mobile optimization is basic, with a mobile subdomain redirect in place. From a security perspective, the platform implements captcha on its reservation form to mitigate spam and uses HTTPS for secure communications. However, the absence of DNSSEC and security headers, along with no visible incident response or security policies, indicates room for improvement. Privacy compliance is basic, with privacy and terms of service pages present but no cookie consent mechanism. Overall, the website is functional and credible with a moderate security posture. Strategic enhancements in security headers, DNSSEC, privacy compliance, and mobile optimization would strengthen its trustworthiness and user protection.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

11 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates as a specialized online marketplace for mortgage vehicles, serving a national Chinese audience. Its competitive advantage lies in its focused niche, offering direct vehicle sales, price evaluations, and a large inventory of brands and models. Revenue likely derives from listing fees, transaction facilitation, and value-added services such as vehicle assessments. The platform supports growth through extensive city coverage and brand variety, appealing to both individual buyers and dealers. Partnerships with analytics providers and cloud hosting indicate a moderate digital maturity. The company maintains a customer service hotline and user agreements, reinforcing its operational legitimacy.

Security posture

The website demonstrates a foundational security posture with HTTPS enabled and captcha protection on forms. However, the lack of DNSSEC and absence of key security headers such as Content-Security-Policy and X-Frame-Options reduce its defense-in-depth. No explicit security or incident response policies are published, and no dedicated security contact channels are visible. The site collects user data via forms and tracks visitors using analytics scripts, but lacks cookie consent mechanisms, which may pose compliance risks under privacy regulations. Overall, the security maturity is moderate but requires enhancements to meet best practices and regulatory expectations.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement essential security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  3. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations and improve user transparency.
  4. Publish a dedicated security policy and incident response contact information to enhance trust and preparedness.
  5. Improve mobile optimization and accessibility to provide a better user experience across devices.

Technical notes

Notes

The website uses a custom or unknown CMS with a technology stack including jQuery 2.0.2 and Swiper.js for UI components. Analytics are provided by Baidu and Ahrefs, indicating integration with major Chinese and international tracking services. Hosting leverages Alibaba Cloud OSS for media assets, suggesting scalable infrastructure. Performance is moderate with room for improvement in mobile responsiveness and accessibility. The site uses meta tags effectively for SEO and includes Open Graph tags for social sharing. However, the absence of modern frameworks or CMS platforms may indicate technical debt or limited modernization. Security configurations lack advanced headers and DNSSEC, representing technical risks that could impact business continuity.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
