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 operates primarily in the non-profit sector focusing on sustainable construction and real estate. Their business model revolves around certification, education, and community building. The organization targets a broad audience including architects, planners, municipalities, developers, investors, and educational institutions. DGNB's partnership with external job platforms and active social media presence indicate a well-integrated ecosystem. The organization's growth is supported by continuous training offerings and events, positioning it as a key influencer in sustainable building practices in Europe.

Security posture

The website enforces HTTPS and uses secure login mechanisms with OAuth2. While basic security headers are likely in place, explicit Content-Security-Policy and security.txt files are absent. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Matomo analytics suggests a privacy-conscious approach. However, the absence of published security policies and incident response information indicates room for improvement in transparency and readiness. Overall, the security posture is good but could be enhanced with additional published policies and security best practices.

Recommendations

  1. Implement a clear cookie consent mechanism to enhance GDPR compliance.
  2. Publish a dedicated security policy and incident response plan on the website.
  3. Add a security.txt file to facilitate vulnerability disclosure.
  4. Introduce Content-Security-Policy headers to mitigate XSS risks.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system. It uses Matomo for analytics, indicating a preference for privacy-friendly tools. The site is hosted on servers indicated by the nameservers agenturserver.co, agenturserver.de, and agenturserver.it. The site demonstrates good mobile optimization, accessibility, and SEO practices. Performance is moderate, likely due to the comprehensive content and media assets. The technical stack is modern and well-maintained, with opportunities to enhance security headers and privacy mechanisms.
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.
