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

The DVGW-Regelwerk Plus website serves as an authoritative platform for technical rules and standards in the gas and water sectors in Germany. Operated by the Deutscher Verein des Gas- und Wasserfaches e.V. (DVGW), a well-established organization founded in 1859, the site provides subscription-based access to regulatory documents and supports professionals in the energy industry. The business model centers on membership and paid access to technical standards, positioning DVGW as a key player in ensuring safety and compliance in the gas and water supply industry. Technically, the website is built on TYPO3 CMS with legacy JavaScript libraries such as jQuery 1.10.2 and Handlebars.js. The site is hosted on INWX nameservers and employs HTTPS with a cookie consent mechanism, reflecting a moderate level of digital maturity. Performance and mobile optimization are adequate but could benefit from modernization, particularly updating JavaScript libraries and enhancing accessibility features. From a security perspective, the site enforces HTTPS and uses cookie consent tools, but lacks explicit security headers and visible incident response policies. The login form uses POST method, and no sensitive data is exposed in the HTML. Analytics are handled via Matomo with moderate user tracking, aligned with privacy compliance. Overall, the security posture is good but could be improved by updating libraries, adding security headers, and publishing security policies. The overall risk assessment is low, with no signs of malicious content or suspicious domain registration. Strategic recommendations include modernizing the tech stack, enhancing security headers, publishing incident response and vulnerability disclosure information, and improving mobile and accessibility features to strengthen trust and compliance.

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 DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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

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 holds a strong market position as a technical standards body in the German energy sector, with a large membership base and authoritative role in gas and water safety. Its competitive advantage lies in its long history, recognized expertise, and comprehensive technical rules. Revenue streams likely include membership fees and subscription sales for access to the Regelwerk Plus platform. The target customers are industry professionals, regulatory bodies, and companies in the gas and water sectors. Growth indicators include ongoing updates to standards and active calls for participation in rule-setting committees. The partnership ecosystem includes related domains such as the main DVGW website and subscription service portals. The organization operates with a clear focus on technical excellence and regulatory compliance.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS, cookie consent, and secure login forms. However, the use of outdated JavaScript libraries such as jQuery 1.10.2 introduces potential vulnerabilities. The absence of security headers like Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No explicit incident response or vulnerability disclosure mechanisms are visible, which could delay response to security incidents. Data protection practices appear aligned with GDPR, supported by a comprehensive privacy policy and cookie consent. Overall, the security culture is professional but could be enhanced by adopting modern security best practices and transparency measures.

Recommendations

  1. Upgrade JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish explicit security policy and incident response information, including a security.txt file for vulnerability disclosure.
  4. Enhance mobile optimization and accessibility to improve user experience and compliance with accessibility standards.
  5. Maintain and regularly update cookie consent mechanisms and privacy policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, combined with legacy JavaScript libraries including jQuery 1.10.2 and Handlebars.js. The hosting is managed via INWX nameservers, indicating a German hosting provider. Performance is moderate with preloading of scripts and stylesheets, but the use of older libraries may impact security and performance. SEO is supported by proper meta tags and canonical links. Accessibility and mobile responsiveness are basic but functional. There is an opportunity to modernize the tech stack, improve security headers, and optimize for mobile and accessibility to reduce technical debt and enhance operational resilience.
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.
