Risk levelHigh

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

青云加速器 is a newly launched free VPN/accelerator service targeting Chinese-speaking users who want to access global websites and video platforms securely and without restrictions. The website offers multi-platform client downloads and emphasizes military-grade encryption and privacy protection. The business model appears to be freemium or ad-supported, with a focus on ease of use and broad server coverage. Technically, the site uses common web technologies such as Bootstrap and jQuery, with moderate performance and good mobile optimization. However, the site lacks formal privacy and cookie policies, contact information, and visible security headers, which impacts its security posture and compliance standing. The domain is recently registered with GoDaddy without privacy protection, consistent with a new service launch. Overall, the site is functional and professional but requires improvements in security and compliance documentation to enhance trust and user confidence.

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

9 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 · found on this site
  • 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

青云加速器 positions itself as a free, reliable VPN/accelerator service with a broad server network across 59 countries and over 150 servers. Its competitive advantage lies in offering military-grade encryption and multi-device support with 24/7 customer service. The target market includes general internet users in China and other regions seeking unrestricted internet access. The business likely generates revenue through ads or premium services, though no explicit monetization details are provided. The ecosystem includes partner domains hosting downloads and tracking scripts. The company is small and newly founded in 2024, with no visible parent or subsidiary companies. Branding is moderately consistent, but the absence of formal policies and contact details limits credibility.

Security posture

The website's security posture is moderate but has notable gaps. The domain uses registrar lock statuses to prevent unauthorized changes but lacks DNSSEC, which could improve DNS security. No HTTPS enforcement or security headers were detected in the provided data, which are critical for protecting users against common web attacks. The absence of privacy and cookie policies indicates poor compliance with data protection regulations such as GDPR. No incident response contacts or vulnerability disclosure policies are present. The use of military-grade encryption is claimed but not verifiable from the site content. Overall, the site needs to implement standard security best practices and compliance documentation to reduce risk and improve user trust.

Recommendations

  1. Implement and enforce HTTPS with HSTS headers to secure all user connections.
  2. Enable DNSSEC for the domain to protect against DNS spoofing and cache poisoning.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  4. Add visible contact information including security incident response contacts.
  5. Incorporate security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.

Technical notes

Notes

The website uses a standard front-end stack including Bootstrap for responsive design, jQuery for DOM manipulation, Swiper for sliders, Toastr for notifications, and Animate.css for animations. It loads analytics scripts from Baidu and tracking scripts from tj.ysponge.com. The hosting provider is inferred as GoDaddy based on WHOIS data and nameservers. Performance is moderate with good mobile optimization. SEO is basic with meta keywords and description but no Open Graph or JSON-LD structured data found. Accessibility features are minimal. The site lacks CMS indicators and appears custom-built or static. Technical debt includes missing security headers and lack of formal compliance documentation.
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.
