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

ERDWERK GmbH is a German-based company specializing in geothermal energy solutions, including consulting, planning, execution, and project management services. The company has a solid market presence with numerous projects primarily in Germany and some international locations. Their website is professionally designed using Drupal 8 CMS, featuring integration with Google Maps and Piwik analytics, indicating a moderate level of digital maturity. Contact information and social media links are clearly provided, enhancing business credibility. From a security perspective, the website uses HTTPS and does not expose sensitive data in the HTML content. However, it lacks visible security headers and explicit privacy or cookie policies, which are important for compliance and security best practices. The absence of WHOIS registration data is a concern, as it reduces trustworthiness despite the professional website presence. No WAF or blocking mechanisms were detected, and the site content is fully accessible. Overall, the website demonstrates a good business and technical foundation but requires improvements in privacy compliance, security headers, and WHOIS transparency to enhance trust and security posture. Strategic recommendations include implementing comprehensive privacy and cookie policies, adding security headers, and clarifying domain registration details.

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

  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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

ERDWERK GmbH operates in the energy sector with a focus on geothermal energy projects. Their business model centers on providing specialized consulting, planning, and project management services for geothermal energy development. The company targets energy sector stakeholders and project developers seeking expert geological and drilling supervision. Their portfolio includes near-surface and deep geothermal projects, as well as balneology applications. The company maintains an active presence on professional social media platforms such as Xing, LinkedIn, and Twitter, supporting their market positioning. The website content and project showcases indicate a medium-sized enterprise with a strong regional focus in Germany and some international projects, reflecting growth and expertise in the geothermal energy market.

Security posture

The website employs HTTPS, ensuring encrypted communication. It uses Piwik (Matomo) for analytics, which is privacy-friendly compared to other analytics platforms. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which are important for mature security governance. The WHOIS data inconsistency raises questions about domain registration transparency. Overall, the security maturity is moderate but can be significantly improved by adopting standard security headers, publishing security policies, and clarifying domain registration information.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish a vulnerability disclosure policy and incident response contact information.
  4. Clarify WHOIS domain registration details to improve trust and transparency.
  5. Enhance accessibility features and SEO metadata to improve user experience and search visibility.

Technical notes

Notes

The website is built on Drupal 8 CMS, leveraging Google Fonts and Google Maps API for enhanced user experience. It integrates Piwik (Matomo) analytics for visitor tracking. The site is mobile responsive with good navigation clarity and professional design. Performance is moderate, with no critical technical issues detected in the HTML content. However, the lack of visible security headers and privacy compliance features indicates areas for technical improvement. No forms were detected in the analyzed content, suggesting limited data collection points. The hosting provider is not explicitly identified. Overall, the technical infrastructure is solid but would benefit from modernization in security and privacy implementations.
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.
