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

Alibaba Cloud Computing (Beijing) Co., Ltd. operates the alidns.com website, providing global public recursive DNS services as part of Alibaba Cloud's internet infrastructure offerings. The website positions itself as a reliable, fast, and secure DNS service provider, targeting both general internet users and enterprise customers. The business is well-established, with a domain age of over 15 years and strong brand association with Alibaba Group. Key services include public DNS resolution, cloud DNS authoritative services, and support for modern DNS security protocols such as DoH and DoT. Technically, the website employs modern JavaScript frameworks and Alibaba's proprietary analytics tools, ensuring good performance and mobile optimization. The hosting is managed by Alibaba Cloud, ensuring robust infrastructure and fast content delivery. However, the site lacks explicit privacy and cookie policies, which is a gap in compliance and user transparency. From a security perspective, the site uses HTTPS and modern tracking scripts but does not disclose security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content. The WHOIS data confirms the domain's legitimacy and consistency with the business entity. Overall, the website is professional and trustworthy but would benefit from enhanced privacy compliance and explicit security disclosures to improve user 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

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 website serves as a key digital asset for Alibaba Cloud's DNS services, targeting a broad audience from individual internet users to enterprise clients. Its market position is strong within China's cloud and internet infrastructure sector, leveraging Alibaba's brand and resources. The business model focuses on providing both free public DNS services and enterprise-grade DNS solutions with advanced features. The presence of SDKs and APIs indicates a developer-focused approach for integration. The site also links to related Alibaba Cloud products, suggesting a comprehensive ecosystem strategy. Growth indicators include continuous domain registration and active analytics tracking. Partnerships are primarily internal within Alibaba's ecosystem, with no external subsidiaries or partners explicitly listed.

Security posture

The security posture is solid with HTTPS enforced and no immediate vulnerabilities visible. The use of Alibaba's analytics and tracking scripts is standard for enterprise sites but lacks transparency in privacy and cookie management. The absence of a published security policy or incident response contact is a notable gap. No security.txt or vulnerability disclosure program is evident, which could hinder responsible vulnerability reporting. The site does not expose sensitive data or use deprecated libraries. Security headers are not explicitly detected in the HTML content, suggesting room for improvement. Overall, the site is secure but could enhance its security maturity by adopting best practices in policy disclosure and user consent.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to inform and obtain user consent for tracking.
  3. Add a security policy page including incident response contacts such as security@ or abuse@ emails.
  4. Provide a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.

Technical notes

Notes

The website uses modern JavaScript frameworks and Alibaba Cloud's proprietary analytics tools, ensuring good performance and mobile responsiveness. The hosting is on Alibaba Cloud, providing robust infrastructure. The site uses Ant Design icons and modular JavaScript loading. SEO is basic with meta tags and Open Graph tags present but no JSON-LD structured data detected. Accessibility features are minimal but present. No CMS is detected, suggesting a custom or proprietary platform. The site loads asynchronously and uses CDN resources from alicdn.com and related Alibaba domains. Overall, the technical implementation is modern and efficient but could improve SEO and accessibility further.
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.
