Risk levelLow

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

MVV Energie AG is a leading German energy company based in Mannheim, offering a broad range of energy products and services including electricity, gas, water, district heating, solar energy, and e-mobility solutions. The company targets both general consumers and business customers within Germany, positioning itself as a major player in the German energy market. The website is professionally designed using TYPO3 CMS, with good SEO and accessibility features, and integrates multiple analytics and marketing tools such as Google Analytics, Facebook Pixel, and HubSpot. Cookie consent is implemented, indicating awareness of privacy compliance requirements. Security posture is adequate with HTTPS enabled, but lacks explicit security headers and published security policies. No privacy policy or terms of service pages were detected in the provided content, which is a compliance gap. Overall, the website is trustworthy and professional but could improve transparency and security documentation.

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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

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

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. 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.

    • Medium

      DMARC not enforcing

      DMARC policy is set to "none"

      What to do: Gradually move to "quarantine" then "reject" policy

    • Medium

      No DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

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

MVV Energie AG operates in the energy sector with a comprehensive portfolio of energy supply and related services. The company leverages digital marketing and analytics tools to engage customers and optimize services. The business model focuses on energy provision and innovative solutions like solar and e-mobility. The website reflects a mature digital presence with consistent branding and good user experience. However, the absence of explicit privacy and security policies online may impact customer trust and regulatory compliance. The integration of multiple external domains for analytics and marketing suggests a robust partnership ecosystem. The company appears to be an enterprise-level organization with a strong market position in Germany.

Security posture

The website employs HTTPS and a cookie consent mechanism, which are positive security and privacy practices. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No incident response or vulnerability disclosure information is published, which limits transparency and preparedness for security incidents. No exposed vulnerabilities or sensitive data were detected in the analyzed content. The use of reputable third-party services for analytics and marketing is noted, but these increase the attack surface and require careful management. Overall, the security maturity is moderate, with room for improvement in policy publication and technical hardening.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website footer or main navigation.
  2. Add terms of service and security policy documents to enhance transparency and compliance.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide explicit incident response contact information, including security@ or abuse@ email addresses.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used open-source content management system. It uses modern web technologies including JavaScript and integrates with multiple third-party services for analytics and marketing. The site is mobile optimized and accessible, with good SEO metadata including Open Graph and Twitter card tags. Performance is moderate, with preconnect and preload hints for resources. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicit in the content. The technical infrastructure supports a professional and scalable web presence but could benefit from enhanced security configurations and clearer documentation of policies.
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.
