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

GLDF.io is the official website for the Global Lighting Data Format, an open, modular XML-based data format developed and maintained by DIAL GmbH and RELUX Informatik AG, two established German companies in the lighting industry. The website serves as a resource hub offering documentation, schema references, and tools for manufacturers and software developers to adopt and implement GLDF. The project is positioned as an emerging industry standard aiming to streamline lighting product data exchange and integration with BIM and lighting planning software. Technically, the site is built on the modern Docusaurus framework with Algolia-powered search, delivering a fast, accessible, and well-structured user experience. Security posture is moderate with HTTPS enforced but lacking advanced security headers and cookie consent mechanisms. The domain registration is transparent and consistent with the business, supporting trustworthiness. Overall, the site is professional and credible, though improvements in privacy compliance and security policies are recommended.

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. 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

  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';…

  3. GDPR outside view

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

    • 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

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention gldf.io, from OffSeq Breach.

No leaked records found

Breach holds no records for gldf.io right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The GLDF project targets lighting manufacturers, software developers, and BIM professionals by providing a comprehensive, open data format for lighting products. Its business model is collaborative and open-source, driven by industry leaders DIAL and RELUX, which enhances its market position as a credible and innovative standard. The partnership ecosystem includes well-known lighting software platforms, reinforcing its adoption potential. The website content and external links reflect a focused and professional approach, with no commercial advertising or tracking beyond essential search functionality. Growth indicators include active GitHub repository and ongoing documentation updates. The absence of direct contact information suggests a focus on community-driven development rather than direct sales or support.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, ensuring encrypted communications. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No forms or input fields reduce attack surface, but lack of published security policies and incident response contacts limits transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the content. Compliance with GDPR is partial, with a privacy policy present but no cookie consent mechanism. Overall, the security posture is adequate for an informational site but should be enhanced to meet best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  4. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update dependencies and frameworks to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Docusaurus v3.7.0, a modern static site generator optimized for documentation sites, combined with Algolia DocSearch for efficient search functionality. The site uses standard HTML5, CSS3, and JavaScript with deferred script loading for performance. Preloading of images and scripts indicates attention to performance optimization. The site is mobile responsive and accessible, with clear navigation and consistent branding. Hosting details are not explicit but DNS uses managed-ip.com name servers. No CMS beyond Docusaurus is detected. Overall, the technical infrastructure is modern, performant, and well-suited for the site's purpose, with opportunities to enhance security configurations.
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.
