Risk levelMedium

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

The website www.yunqishi.net operates as a Chinese-language platform offering software downloads, primarily focused on system reinstallation tools, U disk boot disk creation, and related tutorials. It targets general computer users, especially novices seeking easy-to-use system maintenance solutions. The site provides a broad range of software and video tutorials, positioning itself as a helpful resource in the technology/software niche. Technically, the site uses common web technologies such as jQuery and Swiper.js, and integrates analytics from Baidu and 51.la. The site is accessible over HTTPS and demonstrates moderate performance and mobile optimization. However, it lacks visible advanced security headers and privacy compliance documentation, which are areas for improvement. The absence of WHOIS registration data for the domain raises concerns about domain legitimacy and transparency, impacting overall trust. No adult or explicit content is present, making it safe for general audiences.

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

7 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 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';…
  4. 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 model centers on providing free software downloads and educational content to end users, likely monetized through indirect means such as advertising or affiliate links, though no explicit advertising networks were detected beyond analytics. The platform serves a medium-sized audience interested in system tools and tutorials, with a focus on ease of use for non-technical users. The lack of clear company registration or contact information limits the ability to fully assess business credibility. The site maintains consistent branding and a professional appearance, supporting user trust. The ecosystem includes multiple subdomains for software, Android apps, and games, indicating a diversified content offering within the technology sector.

Security posture

The website employs HTTPS, which is a fundamental security measure. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces its defense against common web attacks. No sensitive data exposure or vulnerable libraries were detected in the provided content. The site lacks visible privacy and cookie policies, which are important for compliance with data protection regulations like GDPR. No incident response or security contact information is provided, limiting transparency and readiness for security events. Overall, the security posture is moderate but could be significantly improved by implementing best practices and compliance documentation.

Recommendations

  1. Implement comprehensive privacy and cookie policies to enhance compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to improve legitimacy.
  4. Provide clear contact information including security incident response channels to improve transparency and readiness.
  5. Regularly audit third-party scripts and analytics integrations to minimize potential vulnerabilities.

Technical notes

Notes

The website uses a traditional web technology stack with jQuery 1.10.1 and Swiper.js for UI components, along with Base64 encoding scripts and analytics from Baidu and 51.la. The site is served over HTTPS with canonical URLs properly set, indicating basic SEO awareness. The site shows moderate performance and good mobile optimization. Accessibility features are basic, with room for improvement. No CMS or hosting provider information was detected. The site structure is clear with multiple categorized sections for software, Android apps, games, and tutorials, supporting good user navigation. Technical debt may exist due to use of older jQuery versions. Overall, the infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
