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

1 finding rated critical or high. Fix these first.

  1. 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

The company targets engineers and technical specialists, providing continuing education through conferences and seminars. Their business model revolves around paid educational events and training programs. The presence of multilingual support (German and English) and partner domains like vdiconference.com indicates a broad market reach. The company leverages social media channels extensively for engagement and marketing. The business appears medium-sized with a focus on education and technology sectors. No parent or subsidiary companies were identified, suggesting an independent operation. The company maintains GDPR compliance and transparent cookie policies, which are critical for operating in the EU market. Their partnership ecosystem includes related conference platforms, enhancing their service offerings.

Security posture

The website enforces HTTPS and uses security best practices such as cookie consent and bot protection via reCAPTCHA. However, no explicit security policy or incident response information is published, which could be improved to enhance transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Cookiebot ensures compliance with cookie regulations and user consent management. Security headers are partially present but could be strengthened by adding explicit Content-Security-Policy and X-Frame-Options headers. The absence of a security.txt file or vulnerability disclosure policy is a gap in their security posture. Overall, the security maturity is good but could benefit from formalized policies and disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Add incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance HTTP security headers by explicitly adding Content-Security-Policy and X-Frame-Options.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used content management system, indicating a stable technical foundation. Integration with Google Tag Manager and Cookiebot shows a modern approach to analytics and privacy compliance. The site loads multiple JavaScript bundles for navigation, forms, and UI components, suggesting a modular and maintainable front-end architecture. Performance is moderate, with room for optimization in script loading and caching. Mobile optimization and accessibility are well addressed, with responsive design and ARIA roles present. The use of structured data (JSON-LD) enhances SEO and semantic understanding by search engines. Hosting details are not explicit but the domain uses name servers consistent with a German hosting provider. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
