Priority findings

6 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

  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

The initiative positions itself as a key player in Germany's renewable energy sector, focusing on geothermal energy as a sustainable heating solution. Its business model is collaborative, involving multiple energy companies, industry partners, and research institutions. The presence of numerous partner logos and external links indicates a broad partnership ecosystem. The target market includes municipalities, energy providers, and government agencies, with a focus on promoting geothermal energy adoption and awareness. The website content and testimonials highlight the initiative's competitive advantage in experience and industry support. Growth indicators include active content updates and engagement with stakeholders. The business operates in the energy sector with a medium organizational size and a history of up to 20 years among members.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, and privacy compliance is evident through cookie consent banners and detailed privacy policies. However, the absence of key security headers such as Content-Security-Policy, HSTS, and X-Frame-Options reduces the overall security posture. No direct vulnerabilities or exposed sensitive data were found in the HTML content. The use of multiple third-party WordPress plugins introduces potential risk if not regularly updated. There is no visible incident response contact or security policy page, which could be improved to enhance readiness. Overall, the site follows good security practices but should strengthen header policies and formalize incident response mechanisms.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Maintain regular updates and security patches for WordPress core and all plugins to mitigate vulnerabilities.
  3. Add a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  4. Conduct periodic security audits and penetration testing to identify and remediate potential risks.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine ranking.

Technical notes

Notes

The website is built on a stable and widely used CMS platform, WordPress 6.8.3, leveraging a variety of reputable plugins for sliders, forms, GDPR compliance, and image lightboxes. The theme used is BeTheme, a popular commercial WordPress theme, ensuring a professional design and responsive layout. Hosting is provided by rzone.de, a known hosting provider. The site loads with moderate performance, likely due to multiple plugins and slider assets. SEO is well addressed with proper meta tags and structured data. Accessibility is basic but could be improved. The technical stack is modern but requires ongoing maintenance to avoid plugin-related security risks. Overall, the infrastructure supports the business goals effectively with opportunities for optimization.
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.
