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

The website cdqoz.com operates as a specialized telecommunications service provider in China, focusing on the application, management, and agency services for 400 telephone numbers. It targets enterprises nationwide, offering multiple service packages tailored to different business sizes and needs. The site positions itself as a legitimate and authorized operator with a broad regional presence through numerous city-specific subdomains. The content is primarily in Chinese and provides detailed service descriptions, pricing, and functional features of 400 telephone services, catering to business customers seeking professional call center and telephony solutions. From a technical perspective, the website employs standard web technologies including jQuery and SuperSlide for UI interactions and slideshows. The site is mobile-optimized with responsive CSS and includes SEO-oriented meta tags and Baidu push scripts to enhance search engine visibility in China. However, no advanced CMS or modern frameworks are detected, and performance is moderate. Accessibility features are basic, and no explicit security headers are observed in the provided data. Security posture is moderate; HTTPS is implied by the use of https URLs, but no explicit security headers or incident response contacts are present. No forms collecting sensitive data are detected, reducing immediate risk exposure. Privacy and cookie policies are absent, indicating compliance gaps with data protection regulations such as GDPR. No contact emails or phone numbers are explicitly provided, which may impact user trust and support accessibility. Overall, the website is functional and professionally presented with good content quality and business credibility. The lack of privacy and cookie policies, absence of security headers, and missing contact information are notable weaknesses. Strategic improvements in compliance documentation, security hardening, and user contact transparency are recommended to enhance trust and regulatory adherence.

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 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

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

cdqoz.com operates in the telecommunications sector, specifically providing 400 telephone number services widely used by Chinese enterprises for customer service and branding. The business model revolves around offering multiple tiered packages with varying pricing and number quality, targeting small to medium-sized businesses and larger enterprises. The company leverages a network of city-specific subdomains to extend its market reach across China, indicating a decentralized regional approach. Competitive advantages include official authorization, a broad selection of numbers, and value-added call center features. Revenue streams likely derive from service package sales and number leasing. The absence of direct contact details online suggests reliance on online chat (QQ) for sales and support. The partnership ecosystem includes multiple related domains and external links to complementary service providers. Growth indicators include active news updates and SEO efforts targeting Baidu. Overall, the company maintains a solid market presence in the niche 400 phone service industry within China.

Security posture

The website demonstrates a moderate security maturity level. HTTPS usage is present, ensuring encrypted communication. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. No forms are present that collect sensitive user data, minimizing immediate data exposure risks. The lack of a published security policy or incident response contact channels indicates limited preparedness for security incidents. No vulnerabilities or outdated libraries were detected in the provided content. Compliance with data protection regulations is weak due to missing privacy and cookie policies. Overall, the security posture is functional but requires enhancements in policy transparency, header implementation, and incident readiness to meet higher standards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve compliance and user trust.
  2. Implement essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance web security.
  3. Provide clear contact information including security and abuse reporting channels.
  4. Ensure HTTPS is enforced site-wide and monitor SSL/TLS configurations for best practices.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a traditional web technology stack with jQuery and SuperSlide for interactive elements. CSS files are organized for desktop and mobile responsiveness, indicating attention to mobile optimization. The site includes Baidu push scripts for SEO purposes, targeting Chinese search engines. No modern JavaScript frameworks or CMS platforms are detected, suggesting a custom or lightweight implementation. Performance is moderate, with no explicit indicators of optimization or CDN usage. Accessibility is basic, with no ARIA roles or landmarks detected in the provided HTML snippet. SEO is supported by meta keywords, description, and viewport settings. The site structure includes multiple city subdomains, indicating a distributed hosting or DNS strategy. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced performance tuning.
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.
