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

The Delfinarium website is an official informational platform for the Zoo Duisburg's dolphinarium, providing educational content about dolphins, their care, and related zoological information. The site targets general visitors and animal enthusiasts, positioning itself as a regional zoological attraction with a focus on dolphin care and education. The business operates as a non-profit entity within the hospitality and non-profit sectors in Germany. Technically, the website is built on TYPO3 CMS with Bootstrap 5 for responsive design, integrating modern tools such as Google Analytics for visitor tracking and Usercentrics for cookie consent management. The site demonstrates good mobile optimization and basic accessibility features, with a moderate performance profile. SEO practices are adequately implemented with proper meta tags and structured navigation. From a security perspective, the site uses HTTPS and incorporates consent management, but lacks visible security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected, though improvements in security headers and formal security documentation are recommended to enhance the security posture. Overall, the website is professional, trustworthy, and compliant with GDPR requirements, with clear contact phone information and social media presence. The absence of email contacts and terms of service pages are minor gaps. The site is safe for general audiences with no adult or questionable content. Strategic recommendations include enhancing security headers, publishing security policies, and adding vulnerability disclosure mechanisms to strengthen trust and compliance.

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.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. 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

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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

Zoo Duisburg operates a specialized dolphinarium as part of its zoological offerings, serving primarily local and regional visitors interested in marine mammals and animal education. The business model is non-profit, focusing on animal care, public education, and conservation awareness. The website supports this by providing detailed information on dolphin species, care practices, medical data, and historical records. Partnerships with recognized zoological associations such as EAZA and WAZA enhance credibility and market positioning. The presence on social media platforms like Facebook and Instagram indicates active engagement with the community. Revenue streams likely include ticket sales and donations. The website's content and structure reflect a stable, medium-sized institution with consistent branding and a clear mission.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent management in place. However, the absence of key security headers (e.g., Content Security Policy, HSTS) and lack of published security policies or incident response contacts indicate areas for improvement. No evidence of vulnerabilities or exposed sensitive data was found, and no security.txt or vulnerability disclosure mechanisms are present. Compliance with GDPR is supported by the privacy and cookie policies. Overall, the security posture is adequate for the business type but could be enhanced by adopting best practices in HTTP security headers and formalizing incident response procedures.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and provide incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Consider adding a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website is built on a modern and stable technology stack using TYPO3 CMS and Bootstrap 5, ensuring responsive design and compatibility across devices. Integration of Google Analytics and Usercentrics indicates a mature approach to analytics and privacy compliance. Performance is moderate, with potential for optimization. The site uses valid meta tags and SEO-friendly structures. However, the lack of visible security headers and limited accessibility features suggest technical debt in security and inclusivity. Hosting details are not explicitly available, limiting full infrastructure assessment. Overall, the technical implementation supports the business needs but can benefit from security and accessibility enhancements.
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.
