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

Windows10之家 is a Chinese-language website specializing in providing clean, professional Windows 10 system images for download, including professional, enterprise, and home editions. The site also offers software downloads, Android apps and games, and tutorials related to Windows 10. It targets Chinese-speaking users seeking reliable Windows 10 installation resources and related content. The website appears to be a niche player in the Chinese Windows 10 system download market, with a small-scale operation and moderate content quality. The presence of an ICP license number indicates regulatory compliance within China. Technically, the website uses older JavaScript libraries such as jQuery 1.7.1 and integrates Baidu analytics and push services. The site structure is well-organized with clear navigation and multiple content categories. Mobile optimization is basic but functional. However, there is no evidence of modern security headers or comprehensive privacy and cookie policies, which limits its compliance posture. From a security perspective, the site does not expose forms collecting sensitive data and uses HTTPS for some resources, but lacks visible security headers like CSP or HSTS. No WHOIS data is available for the domain, which raises questions about domain registration legitimacy, although the website content and ICP license suggest legitimate operation. No contact information or incident response channels are provided, which is a gap in security readiness. Overall, the website is functional and content-rich but lacks critical privacy, security, and contact transparency features. Strategic improvements in security headers, privacy compliance, and contact information would 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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 website operates as a free download portal focusing on Windows 10 system images and related software, targeting Chinese-speaking users. Its business model relies on providing downloadable content and tutorials, likely monetized through advertising and partnerships with related software and gaming sites. The site maintains a broad partnership ecosystem with multiple Chinese software and gaming domains. Growth indicators include regular content updates and a diverse content offering. However, the lack of explicit business contact information and WHOIS transparency may limit business credibility in international contexts.

Security posture

The security maturity level of the website is moderate to low. While HTTPS is used for some resources, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No privacy or cookie policies are present, indicating non-compliance with GDPR and similar regulations. The lack of incident response contact channels and security policies further weakens the security posture. No vulnerable libraries or exposed sensitive data were detected, but the use of an outdated jQuery version could pose risks. Overall, the site would benefit from implementing modern security best practices and compliance frameworks.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against web vulnerabilities.
  3. Provide clear contact information including security incident response channels to improve transparency and readiness.
  4. Upgrade JavaScript libraries to current versions to mitigate known vulnerabilities.
  5. Enforce HTTPS site-wide and ensure all resources load securely to protect user data.

Technical notes

Notes

The website uses a traditional web stack with HTML, CSS, and JavaScript, including jQuery 1.7.1, which is outdated and may have security vulnerabilities. Baidu analytics and push scripts are integrated for tracking and SEO purposes. The site is structured with multiple content categories and uses standard navigation elements. Mobile optimization is basic, with some meta tags for mobile agents. Performance is moderate, with no explicit indicators of advanced hosting or CDN usage. No CMS was detected, suggesting a custom or static site architecture. Technical debt is present due to outdated libraries and lack of modern security features, which could impact long-term maintainability and security.
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.
