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

The website www.dnxitong.com operates as a specialized Chinese platform offering Windows operating system downloads, including Win7, Win10, Win11, and XP versions, alongside software sharing and system tutorials. It targets general users seeking clean and activated Windows system versions and related software tools. The site maintains a consistent brand presence with regular content updates and a clear author identity, positioning itself as a niche resource in the technology sector focused on system software distribution. Technically, the site is built on WordPress using the CorePress theme and incorporates common JavaScript libraries such as jQuery, QRCode.js, NProgress, and Swiper for UI enhancements. The site demonstrates moderate performance and good mobile optimization, with basic accessibility and SEO practices in place. However, there is room for improvement in security headers and privacy compliance. From a security perspective, the site uses HTTPS but lacks critical security headers like Content-Security-Policy and HSTS, which could expose it to certain web-based attacks. No privacy or cookie policies are present, indicating compliance gaps with GDPR and similar regulations. The absence of WHOIS data limits the ability to fully verify domain legitimacy, which slightly impacts trustworthiness. Overall, the site is functional and serves its intended audience well but should prioritize enhancing security measures and privacy compliance to improve user trust and regulatory adherence.

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

www.dnxitong.com operates as a small-scale technology content platform focused on Windows OS and software downloads. Its business model revolves around providing free or unlocked versions of Windows systems and software tools, targeting Chinese-speaking users interested in system installation and software utilities. The platform's competitive advantage lies in its niche focus and regularly updated content. Revenue streams are not explicitly stated but may include advertising or affiliate links. The site maintains partnerships or references to related technology and software domains but lacks formal business registration disclosures. Growth indicators include frequent content updates and an active user engagement model via comments and contact channels.

Security posture

The website exhibits a basic security posture with HTTPS enabled but lacks important security headers such as Content-Security-Policy, X-Frame-Options, and HSTS, which are essential for mitigating common web vulnerabilities. No evidence of vulnerability disclosure or incident response policies is found. Privacy compliance is weak due to the absence of privacy and cookie policies. The site does not expose sensitive data or show signs of malware but would benefit from implementing security best practices and formalizing data protection measures to enhance resilience and user trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve regulatory compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and enable HSTS to strengthen web security.
  3. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  4. Establish a vulnerability disclosure policy or security contact to improve incident response readiness.
  5. Enhance transparency by providing clear business registration information and additional contact methods.

  6. No WAF or blocking mechanisms detected; site is fully accessible.
  7. WHOIS data is missing or unavailable, limiting domain trust assessment.

  9. Website uses WordPress with CorePress theme and common JS libraries.
  10. No explicit advertising or tracking scripts detected.
Technical notes

Notes

The website uses a WordPress CMS with the CorePress theme and integrates several JavaScript libraries for UI and functionality enhancements. The site is mobile optimized and has a clear navigation structure. Performance is moderate, with some lazy loading of images to improve load times. SEO is supported by meta tags and structured navigation. However, the absence of advanced security headers and privacy mechanisms indicates technical debt in security and compliance areas. Hosting provider details are not disclosed, and WHOIS data is unavailable, limiting infrastructure transparency.
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.
