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

2 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

VDI holds a strong market position as a leading engineering association in Europe, leveraging a membership-based business model. Its competitive advantage lies in its large member base and comprehensive technical offerings. Revenue streams likely include membership fees, publications, and event hosting. The target customer segment is professional engineers and technical experts. The organization maintains partnerships and uses multiple external domains for content delivery and services. The website reflects a well-established entity with consistent branding and professional content, supporting growth and member engagement.

Security posture

The website employs HTTPS with strong SSL configuration and security headers, indicating a good security baseline. Cookie consent is implemented with opt-in mechanisms covering preferences, statistics, and marketing cookies, aligning with GDPR requirements. No direct security or incident response policies are published, and no vulnerability disclosure mechanisms are evident. Third-party scripts from Google, Microsoft, Meta, and others are used, which require ongoing monitoring for vulnerabilities. Overall, the security posture is solid but could be enhanced by publishing explicit security policies and providing dedicated security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Provide explicit contact information for security incidents (e.g., security@vdi.de).
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by publishing data protection officer contact details.

Technical notes

Notes

The website is powered by TYPO3 CMS, a mature and extensible content management system, supported by various modern JavaScript libraries such as Slick Slider and Ionicons. Google Tag Manager and Cookiebot are integrated for analytics and privacy compliance. Hosting appears to be managed via NRW.net nameservers, indicating German-based infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Technical debt appears low, but continuous monitoring and updates are recommended to maintain security and performance.
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.
