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

港通智信（深圳）商务有限公司 operates a professional consulting website focused on US company registration, annual compliance, tax filing, auditing, legal notarization, and related business services primarily targeting Chinese-speaking clients. The company positions itself as a specialized service provider with government recognition claims and a comprehensive suite of services including company formation, bank account opening, trademark registration, and overseas business support. The website is well-structured, mobile-optimized, and uses common frontend technologies such as jQuery, Bootstrap, and Swiper for UI components. However, the absence of WHOIS registration data for the domain www.gtzxus.com raises significant concerns about domain legitimacy and ownership verification. The site lacks explicit privacy and cookie policies, which impacts compliance and user trust. Security headers are not detected, though HTTPS usage is implied. Contact information is comprehensive, including multiple phone numbers, emails, and physical addresses in China, Hong Kong, Korea, and the US, enhancing business credibility. Overall, the website demonstrates good content quality and user experience but requires urgent attention to domain registration legitimacy and privacy compliance to improve trustworthiness and security posture.

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. 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';…

  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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 company targets Chinese entrepreneurs and businesses seeking to establish or manage US-based companies, offering a full range of consulting services from company registration to tax and legal compliance. Its business model is service-oriented, generating revenue through consulting fees and service packages. The market position is niche, focusing on cross-border business facilitation between China and the US. The presence of multiple physical addresses and contact channels suggests a medium-sized operation with regional presence. The partnership with byt.zoosnet.net for live chat indicates investment in customer engagement. The lack of WHOIS data is a critical risk factor that could affect client trust and regulatory compliance. The company could benefit from clarifying domain ownership and enhancing transparency through published policies and certifications.

Security posture

The website uses HTTPS (implied by URL) but lacks visible security headers such as Content-Security-Policy, X-Frame-Options, or HSTS, which are important for mitigating common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of outdated jQuery 1.11.3 may pose security risks if not properly patched. The absence of privacy and cookie policies indicates a compliance gap, especially relevant under GDPR and other data protection regulations. Incident response and security policy information are not present, limiting the site's preparedness for security events. Overall, the security posture is moderate but requires improvements in headers, library updates, and compliance documentation.

Recommendations

  1. Verify and register the domain properly to resolve WHOIS inconsistencies and improve trust.
  2. Publish comprehensive privacy and cookie policies to enhance compliance and user trust.
  3. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.
  4. Update JavaScript libraries to current versions to mitigate known vulnerabilities.
  5. Establish and publish security policies and incident response contacts to demonstrate security maturity.

Technical notes

Notes

The website is built using standard web technologies including jQuery 1.11.3, Bootstrap, Swiper, and Font Awesome. It is mobile-optimized with responsive design and includes interactive elements such as live chat via Zoosnet and Baidu Analytics for tracking. The site structure is clear with well-organized navigation and content sections. Performance is moderate, with no explicit indicators of slow loading but no advanced optimization detected. Accessibility is basic, with room for improvement in ARIA roles and semantic markup. SEO is supported by meta tags and structured content but lacks advanced schema markup or JSON-LD data. Hosting provider details are not discernible from the content. Overall, the technical implementation is solid but could benefit from modernization and enhanced accessibility.
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.
