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

The website youxiniao.com is a Chinese mobile gaming portal specializing in heavy mobile games and software downloads. It offers a comprehensive range of services including game downloads, software downloads, news, reviews, rankings, player forums, and special topic collections. The site targets mobile gamers primarily in China and positions itself as a specialized heavy mobile game download portal. Technically, the site uses modern front-end technologies such as HTML5, CSS3, JavaScript, and Swiper.js for carousels, with good mobile optimization and SEO practices. However, there is no evidence of a CMS or hosting provider from the data provided. Security posture is weak due to lack of visible security headers, privacy policies, and incident response information. The WHOIS data is missing, which raises concerns about domain registration legitimacy. Overall, the site is content-rich and professionally designed but lacks transparency in privacy and security 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 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

Youxiniao.com operates as a content portal focused on mobile games and software, monetizing likely through advertising and affiliate links. Its extensive catalog of games and apps, along with news and reviews, suggests a strong content-driven business model targeting Chinese mobile gamers. The site shows consistent branding and regular content updates, indicating a medium-sized operation with a stable user base. The absence of clear business registration or contact information limits the ability to verify corporate legitimacy. No partnerships or subsidiaries are explicitly identified. The site’s market position is that of a niche leader in heavy mobile game downloads in China.

Security posture

The website lacks critical security features such as security headers (CSP, HSTS, X-Frame-Options), privacy and cookie policies, and incident response contacts. There is no evidence of GDPR compliance or data protection officer information. The absence of WHOIS data further reduces trustworthiness. No signs of malware or phishing were detected, and HTTPS usage is assumed but not confirmed from the data. The security score is moderate to low, with recommendations to implement security headers, publish privacy and cookie policies, and provide incident response contacts to improve trust and compliance.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish comprehensive privacy and cookie policies clearly accessible on the website.
  3. Add explicit contact information including security incident response and abuse contacts.
  4. Verify and publish domain WHOIS information or use a reputable registrar with transparent data.
  5. Conduct regular security audits and vulnerability assessments to identify and remediate risks.

Technical notes

Notes

The website uses a modern front-end stack with HTML5, CSS3, and JavaScript libraries like Swiper.js for interactive elements. It supports mobile devices with responsive design and redirects mobile users to a mobile-optimized subdomain. SEO is well addressed with meta tags and structured navigation. However, no CMS or backend technology is identified. Performance is moderate with no explicit indicators of optimization or CDN usage. Accessibility features are basic, and no ARIA or advanced accessibility tags were detected. The site would benefit from enhanced accessibility and performance optimizations.
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.
