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 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 business is positioned as a leading public DNS service provider under Alibaba Cloud, targeting both individual internet users and enterprises requiring DNS solutions. The business model includes free public DNS services and paid enterprise-grade DNS solutions with SDKs and APIs. The company benefits from Alibaba Group's strong market presence and infrastructure. The website content and linked domains reinforce Alibaba's ecosystem, with no suspicious or unrelated domains detected. The lack of direct contact details suggests a focus on self-service and online support channels. The company demonstrates a solid partnership ecosystem within Alibaba's cloud services portfolio.

Security posture

The website enforces HTTPS and uses domain status flags to prevent unauthorized transfers or deletions, indicating good domain security hygiene. However, DNSSEC is not enabled, which could improve DNS integrity and security. No security.txt or incident response contact information is published, limiting transparency for vulnerability reporting. Analytics scripts are present but no sensitive data exposure or vulnerable libraries were detected. The absence of privacy and cookie policies is a compliance gap. Overall, the security posture is good but could be enhanced with DNSSEC and published security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and integrity.
  2. Publish clear privacy and cookie policies with GDPR compliance details.
  3. Add a security policy page including incident response and vulnerability disclosure contacts.
  4. Implement a cookie consent mechanism to comply with privacy regulations.
  5. Consider adding direct contact information for enterprise support and security reporting.

Technical notes

Notes

The website uses modern JavaScript frameworks and libraries, including Ant Design icons and Alibaba's Goldlog analytics platform. The site is hosted on Alibaba Cloud, ensuring robust infrastructure and fast performance. The HTML is well-structured with responsive design elements for mobile optimization. SEO is basic but present with meta tags and Open Graph properties. Accessibility features are minimal but functional. No CMS was detected, suggesting a custom or proprietary platform. The site includes multiple tracking and analytics scripts, indicating moderate user tracking. Overall, the technical implementation is solid with room for improvements in accessibility and SEO.
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.
