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

The website www.dxtong.com represents a Chinese cloud communication service provider specializing in SMS, MMS, video messaging, voice verification, and marketing messaging platforms. The company, 上海互亿文化传播有限公司, claims over 21 years of industry experience and serves over 150,000 enterprise customers. Their platform offers a variety of messaging services with direct operator connections and emphasizes fast delivery, reliability, and brand trust through SMS signature authentication. The website is professionally designed, mobile-optimized, and provides clear navigation and service descriptions targeting enterprises and developers in China. Technically, the site uses modern JavaScript libraries such as jQuery, Swiper, and Layui, and integrates Baidu Analytics for user tracking. However, explicit privacy and cookie policies are absent, and no security headers are detected, which are areas for improvement. The domain WHOIS data is missing, which raises some concerns about domain registration transparency, although the presence of ICP and public security filings supports legitimacy within China. Overall, the site is functional and professional but could enhance security and privacy compliance to improve 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. 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 company operates in the telecommunications and technology sector, providing cloud-based messaging services primarily to Chinese enterprises and developers. Their business model revolves around offering API-driven SMS, MMS, voice, and video messaging solutions with a focus on marketing and verification use cases. The firm leverages direct connections with telecom operators to ensure high delivery rates and fast message transmission. Their market position is strong domestically, supported by long industry experience and a large customer base. Partnerships with service providers like ihuyi.com enhance their customer support and live chat capabilities. The company’s revenue streams likely include subscription and usage fees for messaging services. The website’s extensive list of linked partner domains indicates a broad ecosystem supporting their operations. Strategic observations include the need to improve transparency around privacy and security policies to align with international standards and enhance appeal to global clients.

Security posture

The website demonstrates a moderate security posture. HTTPS is implied by canonical URLs, but no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options are detected in the HTML content. There is no visible exposure of sensitive data or credentials. The absence of privacy and cookie policies, as well as lack of incident response or vulnerability disclosure information, indicates gaps in compliance and security transparency. The use of third-party scripts like Baidu Analytics and live chat widgets introduces potential risk vectors that require regular auditing. The missing WHOIS data reduces domain trustworthiness and could be a concern for phishing or impersonation risks, although the presence of ICP and public security registrations mitigates some risk within China. Recommendations include implementing security headers, publishing privacy and cookie policies, and establishing clear incident response contacts to improve security maturity.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to improve compliance.
  2. Add HTTP security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish security incident response and vulnerability disclosure information to build trust and readiness.
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Clarify domain registration details or use verified WHOIS information to improve domain trust and reduce suspicion.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, Swiper.js for carousels, and Layui as a UI framework. It integrates Baidu Analytics for traffic monitoring and a third-party live chat service from ihuyi.com. The site is mobile-optimized with responsive design and includes SEO best practices such as meta tags and canonical URLs. Performance appears moderate with asynchronous script loading and optimized CSS usage. However, accessibility features are basic and could be improved. The lack of a CMS suggests a custom or static site architecture. Hosting provider details are not evident from the HTML content. Overall, the technical implementation supports a professional user experience but could benefit from enhanced security configurations and accessibility improvements.
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.
