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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

DVGW Kongress GmbH operates as a key event organizer within the German energy and water sectors, leveraging its parent company DVGW's reputation. Its business model centers on delivering specialized events that facilitate knowledge exchange and networking among industry professionals. The company benefits from a clear market niche and a strong partnership ecosystem including DVGW and related service centers. Revenue streams likely derive from event registrations, sponsorships, and agency services. The target customer segments include technical experts, decision-makers, and companies in the gas and water industries. Growth indicators include a robust event calendar and digital event formats. The company maintains a professional online presence with consistent branding and active social media engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a cookie consent mechanism that aligns with GDPR requirements. Use of Matomo analytics indicates a preference for privacy-conscious data collection. However, the absence of explicit security policies, incident response contacts, and security.txt files suggests room for improvement in transparency and readiness. No security headers were detected in the provided data, which could be enhanced to mitigate common web vulnerabilities. No vulnerabilities or exposed sensitive data were found, indicating good operational security. Overall, the security maturity is good but could be elevated by formalizing policies and improving header configurations.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Provide explicit contact channels for security incidents, e.g., security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to enhance transparency and trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a stable technical foundation. It integrates modern JavaScript libraries including Hyphenopoly for hyphenation and WURFL for device detection, enhancing user experience. Matomo analytics is used for privacy-respecting user tracking. The site is mobile optimized with responsive design elements and good SEO metadata. Performance is moderate, with compressed CSS and JS assets. Hosting provider details are not explicit, but the use of Azure CDN for some assets suggests cloud hosting. Technical risks are minimal, though the absence of security headers and formal security policies could pose future risks if not addressed.
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.
