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

DVGW Service & Consult GmbH is a specialized service provider in the German energy and water sectors, offering consulting, IT services, management, and occupational safety solutions. The company operates as a subsidiary or closely affiliated entity of the DVGW association, which has a long-standing history since 1859. Their market position is that of a trusted expert providing technical and organizational support to energy and water industry stakeholders. The website reflects a professional and consistent brand image with clear service offerings and a focus on industry-specific solutions. Technically, the website is built on TYPO3 CMS, leveraging modern web technologies such as jQuery and Bootstrap. It is mobile-optimized and provides a good user experience with clear navigation and relevant content. The site uses HTTPS and cookie consent mechanisms, indicating compliance with GDPR and privacy best practices. However, no explicit security policies or incident response contacts are published, which could be improved. From a security perspective, the site demonstrates a solid posture with no visible vulnerabilities or exposed sensitive data. The use of HTTPS and cookie consent scripts are positive indicators. The absence of security headers and formal security documentation suggests room for enhancement. No WAF or blocking mechanisms were detected, allowing full content accessibility. Overall, the website is trustworthy, professionally maintained, and compliant with relevant privacy regulations. Strategic recommendations include publishing formal security and incident response policies, enhancing security headers, and providing direct contact information for security incidents 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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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"

  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 Service & Consult GmbH operates in a niche market serving the energy and water sectors in Germany. Their competitive advantage lies in their deep industry knowledge combined with IT and management consulting expertise. The business model focuses on providing specialized services including occupational safety, IT solutions, and technical safety management. Revenue streams likely come from consulting contracts, IT service subscriptions, and event hosting. The target customers are energy and water utilities, regulatory bodies, and industry professionals. The company benefits from strong brand association with the DVGW parent organization, enhancing credibility and market reach. Growth indicators include digital service offerings like verifHy and code assignment platforms. The partnership ecosystem includes related DVGW entities and specialized service providers, supporting a comprehensive service portfolio.

Security posture

The current security maturity level is moderate to good. The website enforces HTTPS and uses cookie consent mechanisms, supporting GDPR compliance. No direct security or incident response policies are published, which is a gap in transparency and readiness. No vulnerabilities or sensitive data exposures were detected in the HTML content. The use of third-party scripts for cookie management and analytics should be regularly audited to prevent supply chain risks. The absence of security headers like Content-Security-Policy and X-Content-Type-Options reduces defense-in-depth. Incident response readiness is unclear due to lack of published contacts. Overall, the security posture is adequate for a service website but could be improved with formal policies and enhanced technical controls.

Recommendations

  1. Publish a formal security policy and incident response plan on the website.
  2. Add 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 vulnerabilities.
  5. Enhance accessibility features and provide more detailed privacy compliance information.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, ensuring a stable and scalable platform. The use of modern JavaScript libraries like jQuery and Bootstrap supports responsive design and interactive features. Performance is moderate, with some preloading of scripts and images to optimize loading times. Mobile optimization is good, with separate navigation for mobile devices. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. SEO is addressed with meta tags and canonical links. Hosting provider details are not explicit, but the use of Azure CDN for some assets suggests a cloud-based infrastructure. Overall, the technical implementation is solid with opportunities for modernization and enhanced security controls.
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.
