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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention dzg.de, from OffSeq Breach.

No leaked records found

Breach holds no records for dzg.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

DZG holds a strong market position in the German energy metering industry, supported by subsidiaries such as IEL Industrie-Elektrik GmbH, DZG Metering, and MeterPan GmbH. Their business model focuses on providing integrated metering solutions and services to various energy-related sectors. The website content and navigation clearly reflect their business scope and partnerships. The company emphasizes quality and innovation, with state-recognized testing facilities and a broad product range. No direct revenue or financial data is available, but the medium size and established subsidiaries indicate a stable business operation.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism, reflecting good privacy practices. However, no explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present. No security headers were detected in the HTML content, which could be improved to enhance protection against common web threats. The absence of exposed sensitive data and use of modern libraries like jQuery and Bootstrap indicate a reasonable security baseline. The social feed widget is loaded only after user consent, aligning with privacy best practices. Overall, the security posture is good but could benefit from additional hardening and transparency.

Recommendations

  1. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve web security.
  2. Publish a dedicated security policy page and provide clear incident response contact information to enhance trust and readiness.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Consider adding explicit company contact emails and phone numbers on the website for easier communication and transparency.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap and jQuery, ensuring a modern and responsive design. The use of Magic360 and Elfsight widgets adds interactive and social features. Performance is moderate with good mobile optimization and SEO practices. No major technical debt or outdated libraries were detected. However, the lack of visible security headers and limited analytics integration suggest areas for technical improvement. Hosting provider details are not disclosed, and no advanced platform integrations were identified. Overall, the technical infrastructure supports the business needs effectively but could be enhanced for security and analytics.
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.
