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

The website duchengqihuo.com operates as a Chinese-language software acceleration and VPN app download portal, focusing on providing users with various acceleration tools for Android and Apple platforms. The business model centers on promoting and distributing acceleration software, targeting general internet users seeking improved network performance. The site appears to be relatively new, with domain registration dating back to early 2022, and does not disclose detailed company or contact information, which limits transparency. Technically, the site employs older JavaScript libraries such as jQuery 1.11.1 and uses Cloudflare for DNS services, though DNSSEC is not enabled. The site includes Matomo analytics for user tracking but lacks visible security headers and privacy or cookie policies, indicating a basic level of digital maturity. The website design and content quality are functional but basic, with moderate mobile optimization and SEO. From a security perspective, the absence of security headers, lack of DNSSEC, and missing privacy and cookie policies represent gaps in best practices. No forms or sensitive data collection mechanisms were detected, reducing immediate risk exposure. The WHOIS data shows consistent domain registration with no privacy protection, supporting legitimacy but highlighting opportunities for improved security hardening. Overall, the site presents a low to moderate risk profile with room for improvement in security posture, privacy compliance, and business transparency. Strategic enhancements in these areas would strengthen trust and compliance, benefiting both users and the business.

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 website targets the technology sector, specifically focusing on network acceleration and VPN-related software. Its market positioning is that of a niche software download portal catering primarily to Chinese-speaking users. The business model appears to be based on software promotion and distribution, possibly monetized through affiliate links or advertising, though no explicit monetization details are provided. The extensive list of external linked domains suggests a broad partnership ecosystem within the acceleration and VPN niche. Growth indicators are limited due to lack of business disclosures. The absence of contact and company information reduces credibility and may hinder user trust and partnership opportunities.

Security posture

The current security maturity level is basic. Key vulnerabilities include the lack of DNSSEC, absence of security headers, and missing privacy and cookie policies. No incident response or vulnerability disclosure mechanisms are evident. The use of an outdated jQuery version may expose the site to known JavaScript vulnerabilities. The site does not collect user data via forms, which reduces attack surface but also limits user engagement capabilities. Compliance gaps with GDPR and other privacy regulations are apparent due to missing policies and consent mechanisms. Overall, the security culture appears minimal, with significant room for improvement to meet industry best practices.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement HTTPS with strong TLS configuration and verify SSL status.
  3. Add comprehensive privacy and cookie policies with clear GDPR compliance statements.
  4. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Upgrade JavaScript libraries to current secure versions to mitigate vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery 1.11.1 and Unslider for UI components, indicating legacy technology usage. Hosting appears to leverage Cloudflare DNS services, but no CMS or modern frameworks are detected. Performance is moderate with basic mobile optimization and SEO. The site lacks accessibility features and modern technical enhancements. The presence of Matomo analytics shows some level of user behavior tracking. Technical debt is evident in outdated libraries and missing security configurations. Modernization opportunities include adopting a CMS or framework for better maintainability, improving accessibility, and enhancing 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.
