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

第一手游网 is a Chinese mobile gaming media platform providing game downloads, news, reviews, and guides primarily targeting mobile gamers in China. The website is well-structured with frequent content updates, including game rankings, gift packages, and original game evaluations. The platform positions itself as a trusted source for mobile gaming information and services in the Chinese market. Technically, the site uses HTTPS and common JavaScript libraries, with moderate performance and good mobile optimization. However, it lacks some modern security headers and cookie consent mechanisms, which may affect privacy compliance. The absence of WHOIS data reduces domain trustworthiness, but the site maintains consistent branding and professional content. Overall, the site is functional and relevant for its audience but could improve security and privacy practices.

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

The business operates in the media sector focused on mobile gaming content and services. It leverages affiliate marketing and content-driven engagement to attract a large user base interested in mobile games. The platform offers a variety of services including game downloads, news, strategy guides, and gift packages, catering to gamers seeking comprehensive mobile gaming resources. The company appears medium-sized with a history dating back to 2013, serving primarily the Chinese market. Partnerships with various gaming and software sites are evident through external links. The business model relies on content monetization and advertising, with a focus on maintaining updated and relevant gaming information to retain user engagement.

Security posture

The website enforces HTTPS, which is a fundamental security measure. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No evidence of exposed sensitive data or vulnerable libraries was found. The site does not provide a public security policy or incident response contact, nor a vulnerability disclosure program, which limits transparency and readiness for security incidents. The absence of cookie consent mechanisms also indicates potential non-compliance with privacy regulations. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, privacy controls, and security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  2. Add a cookie consent banner and detailed cookie policy to improve privacy compliance and user transparency.
  3. Publish a clear security policy and provide incident response contact information to build trust and readiness.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features and mobile usability to improve user experience and broaden audience reach.

Technical notes

Notes

The website uses standard web technologies including JavaScript, jQuery, and Baidu Analytics for tracking. It loads external scripts and images from multiple domains, including ad networks. The site is mobile-optimized with responsive design and redirects mobile users to a mobile-specific subdomain. Performance is moderate with no major issues detected. The lack of a detected CMS suggests a custom or proprietary platform. There is no clear hosting provider identified from the content. SEO is supported by meta tags and structured navigation. Technical debt is minimal but security and privacy technical implementations need enhancement to meet modern standards.
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.
