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 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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  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

VSB Gruppe operates in the renewable energy sector with a diversified portfolio including wind and solar energy projects, battery storage solutions, and e-mobility services. Its business model combines project development, energy production, and operational services, supported by a skilled workforce of over 500 employees. The company benefits from its association with TotalEnergies, which likely provides financial stability and strategic advantages. The website's multilingual support and European country-specific pages indicate a broad geographic reach and customer base. Marketing and analytics tools are used responsibly with consent mechanisms in place, reflecting a mature digital strategy. The company emphasizes innovation and sustainability, positioning itself as a key player in Europe's energy transition.

Security posture

The website enforces HTTPS and includes multiple security headers such as Strict-Transport-Security, X-Content-Type-Options, and Content-Security-Policy, indicating a robust security baseline. The use of a consent management platform (Usercentrics) aligns with GDPR requirements, enhancing privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of publicly available security policies or incident response contacts suggests room for improvement in transparency and preparedness. No vulnerability disclosure program or security.txt file was found, which could be beneficial for responsible vulnerability management. Overall, the security posture is strong but could be enhanced by publishing explicit security governance information.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Enhance data retention policy disclosures to align with GDPR best practices and user expectations.
  4. Regularly audit third-party scripts and tracking tools to ensure no vulnerable or deprecated libraries are used.
  5. Maintain and update WHOIS information where possible to improve domain transparency and trust signals.

Technical notes

Notes

The website is powered by TYPO3 CMS, a mature and widely used content management system, indicating a stable and scalable platform. It integrates modern web technologies including Lottie animations for enhanced user experience and Usercentrics for consent management, reflecting compliance with privacy regulations. Google Tag Manager and LinkedIn Insight are used for analytics and marketing, with appropriate asynchronous loading to optimize performance. The site demonstrates good mobile optimization and accessibility features, contributing to a positive user experience. Performance is moderate, with potential for further optimization in loading times and resource management. The technical infrastructure supports the company's business goals effectively but could benefit from enhanced hosting provider transparency and continuous performance monitoring.
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.
