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

6 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

    • 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

  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 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

DGNB GmbH holds a strong market position as a leading provider of sustainable building education and certification services. Its business model revolves around offering modular training and recognized certifications, appealing to a wide range of stakeholders including architects, energy experts, and companies. The company leverages partnerships with professional bodies like Architektenkammern and dena to enhance credibility and reach. The presence of international consultants and events indicates growth and global outreach. Revenue streams likely include course fees, certification charges, and corporate training contracts. The website's integration with job portals and social media reflects a well-rounded ecosystem supporting recruitment and community engagement.

Security posture

The website exhibits a solid security posture with mandatory HTTPS, secure OAuth2 login flows, and no visible exposure of sensitive data. Use of Matomo analytics aligns with privacy best practices. However, explicit security headers such as Content-Security-Policy and X-Content-Type-Options are not evident and could be added to enhance protection against common web threats. No vulnerabilities or malware indicators were found in the content. Incident response and security policy pages are not explicitly present, which could be an area for improvement. Overall, the site is secure for users and business operations but could benefit from enhanced header policies and documented incident response procedures.

Recommendations

  1. Implement and enforce Content-Security-Policy and X-Content-Type-Options headers to strengthen browser security.
  2. Publish a dedicated security policy and incident response information to improve transparency and preparedness.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  4. Enhance visibility of data protection officer contact details to comply fully with GDPR transparency requirements.
  5. Continue leveraging privacy-respecting analytics and maintain clear cookie consent mechanisms.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system suitable for enterprise-grade sites. The use of Matomo analytics indicates a focus on privacy and data protection. Hosting on agenturserver nameservers suggests professional managed hosting. The site is mobile optimized with responsive design and good accessibility features. SEO is well addressed with comprehensive meta tags, Open Graph, and JSON-LD structured data. Performance is moderate, likely due to rich content and images, but overall user experience is smooth. There is room for technical modernization by adding advanced security headers and possibly upgrading to newer frontend frameworks for enhanced interactivity.
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.
