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

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Duda operates in the competitive website builder market with a focus on professional users and agencies, differentiating itself through AI capabilities and white label offerings. Its business model is SaaS-based, generating revenue from subscriptions and enterprise plans. The platform's integration with localization, analytics, and consent management tools indicates a global and privacy-conscious approach. The company maintains a consistent brand and professional content quality, supporting its market position. While WHOIS data is privacy-protected, the domain and website maturity suggest a stable and legitimate business. The absence of explicit security and vulnerability disclosure policies may reflect a cautious approach or an opportunity to enhance transparency. Duda's ecosystem includes partnerships with analytics and marketing providers but no direct subsidiary or partner domains were identified in the content.

Security posture

The website demonstrates a strong security posture with enforced HTTPS, modern security headers, and no visible exposure of sensitive data. Cookie consent is managed via OneTrust, supporting GDPR compliance. The use of reputable third-party scripts is evident, though continuous monitoring for vulnerabilities is recommended. The lack of a published security policy, incident response plan, or vulnerability disclosure program limits transparency and may impact trust for security-conscious clients. No critical vulnerabilities or suspicious patterns were detected in the analysis. Recommendations include publishing security documentation and providing dedicated security contact channels to improve incident handling readiness and customer confidence.

Recommendations

  1. Publish a detailed security policy and incident response plan accessible on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact emails such as security@duda.co or abuse@duda.co.
  4. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  5. Enhance accessibility features to meet or exceed WCAG standards for broader compliance.

Technical notes

Notes

The website is built on the Duda proprietary CMS platform, utilizing modern JavaScript, jQuery, and FontAwesome for UI components. It integrates Google Tag Manager, OneTrust for cookie consent, Vidyard for video content, and Localize for multilingual support. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Performance is fast with efficient CSS loading strategies. Hosting details are not explicitly disclosed but likely leverage cloud infrastructure. No technical debt or deprecated technologies were observed. Opportunities exist to improve technical documentation and security transparency to align with enterprise-grade expectations.
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.
