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

The website gzzhouyuan.com operates as a platform offering free and trial-based network acceleration software primarily targeting Chinese-speaking users interested in VPN and network speed enhancement tools. The site features multiple software download links for Android and Apple platforms, focusing on 5G network acceleration. The business model appears to be centered on providing free acceleration tools with limited direct monetization visible. The market position is unclear due to lack of business information and branding consistency. Technically, the website uses older JavaScript libraries such as jQuery 1.11.1 and Unslider for UI components, with Matomo analytics for tracking. The site lacks modern security practices such as HTTPS enforcement and security headers, and no CMS or hosting provider information is evident. Performance and mobile optimization are basic, with moderate SEO and accessibility features. From a security perspective, the site demonstrates a weak posture with no visible privacy or cookie policies, no incident response contacts, and no security certifications. The absence of HTTPS and security headers increases risk exposure. No forms or sensitive data collection points are present, reducing some risk but also limiting user engagement. The site does not appear to be blocked or protected by a WAF. Overall, the website presents a low trust profile with minimal compliance and security measures. Strategic improvements in security, privacy compliance, and business transparency are recommended to enhance credibility and user trust.

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 site targets users seeking free or trial VPN and network acceleration services, primarily in the Chinese market. It leverages a network of related acceleration service sites as indicated by numerous external partner links. The business model is likely based on software distribution and possibly affiliate marketing, though no direct monetization is visible. The lack of company information and contact details limits trust and may hinder growth. The site’s competitive advantage is unclear, and it appears to operate as a small-scale technology service provider with limited market differentiation.

Security posture

The security maturity level is low, with no HTTPS enforcement, no security headers, and no visible privacy or cookie policies. The use of outdated JavaScript libraries may introduce vulnerabilities. No incident response or security contact information is provided, indicating poor readiness for security incidents. Compliance with GDPR or other data protection regulations is not evident. The site does not collect user data via forms, which reduces some risk but also limits engagement. Overall, the security posture requires significant improvement to meet modern standards.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information including security incident response channels.
  5. Update JavaScript libraries to current versions to mitigate known vulnerabilities.

Technical notes

Notes

The website uses legacy JavaScript libraries and basic UI frameworks without modern frontend frameworks or CMS. Performance is moderate with some mobile responsiveness but limited accessibility features. SEO is basic with meta tags present but no structured data or Open Graph tags. Hosting and infrastructure details are not disclosed. The site relies on external scripts from multiple domains, which may introduce security risks. There is opportunity to modernize the tech stack, improve performance, and enhance 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.
