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

成都联联好信息科技有限公司 operates as a technology service provider specializing in website construction, design, responsive development, and digital marketing solutions. The company targets primarily small to medium-sized enterprises seeking comprehensive digital transformation services including website building, internet marketing, and multi-channel program development such as WeChat mini programs and apps. Their market position is supported by over 11 years of experience and a portfolio of more than 2000 website projects serving over 1200 clients. Technically, the website employs modern front-end technologies including jQuery, Swiper.js, WOW.js, and CSS animations, ensuring a responsive and visually engaging user experience. The site is mobile-optimized and structured with SEO best practices in mind, although accessibility features are basic. The CMS appears to be DedeCMS based on content references. From a security perspective, the site lacks visible security headers and privacy compliance documentation, which poses risks in terms of data protection and regulatory adherence. The use of an external third-party script from bytegoofy.com introduces potential privacy concerns. The absence of WHOIS registration data for the domain raises questions about domain legitimacy and ownership transparency. Overall, the website is functional and professional but requires improvements in security posture, privacy compliance, and domain registration transparency to enhance trustworthiness and regulatory adherence.

NIS2 Art. 21(2)

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 positions itself as a specialized provider in the digital services sector, focusing on website and application development tailored to business needs. Their competitive advantage lies in extensive experience, a broad client base, and a comprehensive service offering that includes marketing and sales promotion. The business model is service-oriented with direct client engagement via multiple communication channels, including QQ instant messaging and telephone support. Growth indicators include a large number of completed projects and positive client testimonials. The partnership ecosystem is limited to internal references and no external business partners or subsidiaries are identified from the data.

Security posture

The current security maturity level is basic with no advanced security headers or documented policies. The lack of HTTPS verification in the provided data is a concern, although it cannot be confirmed if HTTPS is enforced. No forms collect sensitive data, reducing immediate risk, but the absence of privacy and cookie policies indicates compliance gaps with GDPR and similar regulations. Incident response and vulnerability disclosure mechanisms are not present. The use of third-party scripts without clear privacy disclosures further weakens the security posture. Overall, the site would benefit from implementing standard security best practices and compliance documentation.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and other data protection regulations.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  4. Review and audit third-party scripts for privacy and security risks, removing or replacing those that pose concerns.
  5. Verify domain registration status and update WHOIS information to improve trust and legitimacy perception.

Technical notes

Notes

The website uses a modern front-end technology stack with jQuery, Swiper.js for sliders, WOW.js for animations, and CSS3 for styling. The site is responsive and mobile-friendly, with a clear navigation structure and SEO-optimized meta tags. The CMS is likely DedeCMS, a popular Chinese content management system. Performance is moderate with no explicit indicators of slow loading but could be improved by optimizing external script usage. Accessibility is basic, lacking ARIA roles or other advanced features. Technical debt appears low but the absence of security headers and privacy compliance documentation indicates areas for modernization and risk mitigation.
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.
