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

Cloud DNS Ltd operates the ClouDNS platform, a leading DNS hosting provider offering a range of services including free DNS hosting, premium DNS, DDoS protected DNS, GeoDNS, and domain registration. The company emphasizes high performance and reliability, holding the #1 spot for raw DNS performance according to DNSPerf as of May 2025. Their global infrastructure spans multiple data centers worldwide, supporting a broad international customer base. The website is professionally designed, mobile-optimized, and provides clear navigation and comprehensive service information. Technically, the site leverages modern JavaScript libraries such as jQuery and AJAX for dynamic content loading, with a focus on performance and user experience. The presence of structured data (JSON-LD) enhances SEO and business transparency. Security practices include HTTPS enforcement and use of CAPTCHA for forms, though formal security policies and incident response disclosures are absent. The security posture is strong with no evident vulnerabilities or exposed sensitive data, but could be improved by adding security headers and publishing formal security and incident response policies. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. The WHOIS data aligns well with the website claims, supporting legitimacy and trustworthiness. Overall, ClouDNS presents a mature, trustworthy, and technically sound DNS hosting service with a strong market position. Strategic improvements in security policy transparency and incident response readiness would further enhance their security posture and customer confidence.

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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

ClouDNS is positioned as a competitive DNS hosting provider with a freemium business model, offering both free and paid premium services. Their market advantage lies in high DNS performance, global Anycast network, and comprehensive DNS-related services including monitoring and SSL certificates. The company targets businesses and individuals requiring reliable DNS management, with a focus on uptime and security. Their partnership with cloudprima.com for DDoS protected VPS services indicates an ecosystem approach. The presence of affiliate and reseller programs suggests diversified revenue streams and growth strategies. Customer testimonials and social proof reinforce their market credibility.

Security posture

The website demonstrates a solid security foundation with HTTPS, CAPTCHA integration, and no visible sensitive data leaks. However, the absence of published security policies, incident response plans, and vulnerability disclosure mechanisms indicates room for maturity. No security headers were detected in the provided data, which could be added to mitigate common web attacks. The company should consider formalizing and publishing these policies to align with best practices and compliance requirements such as GDPR and NIS2. Incident response contact channels are not publicly listed, which may delay handling of security incidents.

Recommendations

  1. Publish a formal security policy and incident response plan on the website.
  2. Implement and disclose a vulnerability disclosure program or security.txt file.
  3. Add security HTTP headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Enhance transparency by providing direct security contact emails (e.g., security@cloudns.net, abuse@cloudns.net).
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern JavaScript-based front end with jQuery and AJAX for dynamic content loading, enhancing user experience and responsiveness. The presence of structured data (JSON-LD) improves SEO and semantic understanding by search engines. The site is mobile-optimized with responsive CSS and supports multiple languages, indicating a global target audience. Performance indicators suggest fast loading times. No CMS was detected, implying a custom or proprietary platform. Hosting provider details are not explicit but the global Anycast DNS network and multiple data centers indicate a robust infrastructure. Technical risks are minimal but could be reduced further by implementing security headers and formalizing security policies.
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.
