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

4 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. 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 DVGW operates as a non-profit entity providing education and technical standards in the energy sector, particularly gas and water. Its business model revolves around membership services, vocational training, and certification. The website reflects a mature digital presence with integrated social media and partner links. The organization leverages partnerships with related domains to extend its service offerings. The target customers are technical professionals, engineers, and specialists seeking continuous education and certification. The site content and structure support a high level of user engagement and trust, positioning DVGW as a leading competence network in its sector.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent management, and no visible exposure of sensitive data. The use of Piwik/Matomo analytics indicates privacy-conscious tracking. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection against common web attacks. There is no public security policy or incident response contact information, which could be added to improve transparency and readiness. No vulnerabilities or malicious scripts were detected in the provided content.

Recommendations

  1. Implement and enforce Content-Security-Policy header to mitigate XSS and data injection risks.
  2. Add X-Frame-Options and X-Content-Type-Options headers to prevent clickjacking and MIME sniffing.
  3. Publish a dedicated security policy and provide incident response contact channels.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update them timely.
  5. Enhance user trust by providing more visible certifications or trust seals on the website.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, combined with Bootstrap for responsive design and JavaScript libraries for interactivity. Hosting is managed via INWX, a reputable German provider. Performance is moderate with optimized images and lazy loading techniques. The site is mobile-friendly and accessible, with good SEO metadata and structured navigation. Some technical debt may exist in the form of missing security headers and potential improvements in script loading strategies. Overall, the technical infrastructure supports the business goals effectively with room for modernization in security and performance optimization.
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.
