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

The website www.technisches-sicherheitsmanagement.de represents the Technisches Sicherheitsmanagement (TSM) program operated by DVGW e.V., a prominent organization in the German energy sector. The site offers comprehensive information and services related to voluntary self-assessment and verification of technical safety management for gas and water supply companies. It positions itself as a trusted partner providing independent expert reviews, guidelines, and service coordination through its subsidiary DVGW Service & Consult GmbH. The business model focuses on compliance, efficiency, and transparency in technical process management, targeting medium to large energy sector enterprises in Germany. Technically, the website is built on TYPO3 CMS, leveraging modern JavaScript libraries and frameworks such as jQuery and Bootstrap. It integrates Matomo analytics for user tracking and employs a cookie consent mechanism compliant with GDPR. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although some accessibility features could be enhanced. Performance is moderate, with room for optimization. From a security perspective, the site enforces HTTPS and uses cookie consent banners to manage privacy. However, explicit security headers are not detected, and no public incident response or vulnerability disclosure policies are published. No vulnerabilities or exposed sensitive data were found in the content. The domain registration data aligns well with the business identity, supporting legitimacy and trustworthiness. Overall, the website presents a professional, trustworthy, and compliant digital presence for a specialized service in the energy sector. Strategic improvements in security headers, incident response transparency, and accessibility would further strengthen its posture.

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

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 e.V. holds a strong market position as a key technical safety management authority in the German energy sector, offering voluntary compliance verification services that enhance organizational safety and regulatory adherence. The business benefits from a clear partnership ecosystem including its service subsidiary and related organizations. Its competitive advantage lies in independent expert validation and comprehensive guidelines tailored to the gas and water supply industries. The business model is service-oriented, generating revenue through verification processes, training, and consulting. The target customers are utility companies and industrial enterprises requiring compliance with technical safety standards. Growth indicators include extensive regional best practice networks and event offerings. The company maintains a consistent brand and content strategy focused on trust and professionalism.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, GDPR-compliant cookie consent, and no visible sensitive data exposure. The absence of security headers such as Content-Security-Policy and X-Frame-Options is a minor gap. No incident response or vulnerability disclosure information is publicly available, which could limit transparency and responsiveness to security events. The use of independent experts for TSM verification adds a layer of operational security assurance. Overall, the site is secure but could improve by publishing explicit security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish an incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system widely used in enterprise environments. It uses modern front-end technologies including Bootstrap for responsive design and jQuery for DOM manipulation. The integration of Matomo analytics indicates a preference for privacy-conscious tracking. The site loads multiple JavaScript assets asynchronously and employs cookie consent management via 2b-advice services. Performance is moderate with potential for optimization in asset delivery and caching. The site is mobile-optimized and SEO-friendly with proper meta tags and canonical URLs. No major technical debt or outdated technologies were detected.
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.
