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

The website yyhaomawang.com operates as a specialized e-commerce platform focused on the trading of YY numbers and channels, a niche digital goods market primarily serving Chinese users. The business claims to be the largest and safest platform in this domain, offering various YY number types and channel trading services. The company behind the domain is Chengdu West Dimension Digital Technology Co., Ltd., with domain registration consistent with the business profile and location in China. The site content is primarily in Chinese and targets general users interested in YY number trading. Technically, the website employs a modern JavaScript stack including Vue.js, jQuery, Swiper.js, and Clipboard.js, indicating a moderate level of digital maturity. The site is moderately optimized for performance and mobile use but lacks advanced accessibility and SEO features. Analytics are implemented via 51.la, a Chinese analytics service, with moderate user tracking. From a security perspective, the site uses HTTPS but lacks DNSSEC and important security headers, which lowers its security posture. There are no visible privacy or cookie policies, nor incident response contacts, indicating compliance gaps with data protection regulations such as GDPR. The domain registration is legitimate and consistent, but the absence of privacy and security policies reduces trustworthiness. Overall, the website presents a functional but basic e-commerce platform with moderate business credibility but notable gaps in privacy compliance and security best practices. Strategic improvements in security headers, privacy policies, and incident response readiness are recommended to enhance trust and compliance.

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

8 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 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 platform targets a niche market of YY number and channel trading, positioning itself as the largest and safest provider in China. Its business model revolves around digital goods e-commerce, with revenue likely generated from sales of YY numbers and related services. The target customers are users of the YY platform seeking premium or special numbers and channels. The company operates independently without disclosed subsidiaries or parent companies. The partnership ecosystem includes related YY number sites as indicated by footer links. Growth indicators are limited but the domain age and consistent registration suggest stable operations since 2020.

Security posture

The security maturity of the website is basic. HTTPS is enabled, but DNSSEC is not, and no security headers such as Content-Security-Policy or X-Frame-Options are detected. There is no published privacy or cookie policy, nor incident response contact information, which are critical for compliance and user trust. The use of third-party analytics (51.la) introduces moderate tracking without visible consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the site requires improvements in security headers, privacy compliance, and incident response readiness to meet modern security standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to comply with data protection regulations.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear incident response contact information to handle security issues and abuse reports.
  5. Review and improve SSL/TLS configuration and ensure all resources load securely.

Technical notes

Notes

The website uses a combination of Vue.js framework and common JavaScript libraries like jQuery, Swiper.js for UI components, Clipboard.js for clipboard interactions, and Layer.js for UI layers. The site is moderately optimized for performance with lazy loading of images and asynchronous script loading. Mobile optimization is basic with a fixed viewport width of 1200px, which may limit responsiveness on smaller devices. SEO is basic with meta keywords and description but lacks Open Graph or structured data markup. Hosting provider details are not explicit but the registrar is a Chinese digital technology company. The site uses 51.la analytics for user tracking.
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.
