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

DGNB GmbH operates the DGNB Navigator, a specialized online platform dedicated to sustainable building products. The platform connects manufacturers providing detailed sustainability data with architects, planners, and DGNB auditors, facilitating informed product selection and integration into DGNB certification processes. The website is professionally designed, multilingual (German and English), and supported by a mature CMS (TYPO3). It hosts a large ecosystem of partners and manufacturers, reinforcing its market position as a unique sustainability-focused product database in the construction sector. Technically, the site is well-structured and mobile-optimized, though it lacks some advanced security headers and explicit privacy/cookie policies. Security posture is moderate with HTTPS usage but could be improved with better header policies and incident response information. Overall, the site is trustworthy and serves a niche but important role in sustainable construction, with room for enhanced privacy compliance and security best practices.

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 targets manufacturers, architects, planners, auditors, and building owners interested in sustainable construction products. Its business model combines free access for research with paid product publication for manufacturers, positioning itself as a market leader in sustainability transparency. The extensive partner network and integration with DGNB certification software provide competitive advantages. The company leverages digital platforms to enhance market reach and influence in the green building sector. Growth potential exists in expanding language support and enhancing digital services. The partnership ecosystem is broad, including many well-known manufacturers and suppliers, indicating strong industry acceptance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web threats. There is no public incident response or vulnerability disclosure information, which could hinder rapid response to security issues. Forms use POST methods but no visible CAPTCHA or anti-bot measures are detected. Privacy compliance is limited, with no clear cookie consent or privacy policy on the main page, posing potential GDPR compliance risks. Overall, the security posture is adequate but could benefit from enhancements in headers, policies, and transparency.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  2. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Publish incident response and vulnerability disclosure contacts to enhance transparency and readiness.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider integrating analytics with privacy-respecting configurations to monitor usage and improve services.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable technical foundation. The use of compressed CSS and JavaScript assets suggests optimization efforts. The site is mobile-optimized with responsive design and includes SEO best practices such as meta tags, Open Graph, and JSON-LD structured data. Hosting is managed via webix.de nameservers, a professional hosting provider. Performance is moderate with no evident blocking scripts or heavy third-party integrations. However, the absence of visible analytics or tracking scripts limits insights into user behavior. The technical stack is modern but could be enhanced with improved security configurations and privacy tools.
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.
