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

Biogas liefert is an educational and advocacy website operated by Fachverband Biogas, focusing on promoting biogas as a sustainable and flexible energy source in Germany. The platform provides informative content aimed at a general audience interested in renewable energy and the energy transition. The site is positioned as a niche player within the energy sector, leveraging official biogas branding and social media channels to reach its audience. Technically, the website uses modern JavaScript modules and SVG graphics, hosted on servers associated with kasserver.com. The site is mobile-optimized with a good user experience but lacks advanced technical frameworks or CMS indications. Security posture is basic, with no evident security headers or published policies, and no forms or data collection mechanisms are present. Privacy and cookie policies are absent, which impacts compliance and trust. Overall, the site is functional and professional but would benefit from enhanced security and privacy measures.

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

11 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. 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"

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

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention biogas-liefert.de, from OffSeq Breach.

No leaked records found

Breach holds no records for biogas-liefert.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

The website serves as an informational platform for biogas, likely supported by the Fachverband Biogas association. It targets environmentally conscious individuals and stakeholders interested in renewable energy. The business model appears to be advocacy and education, with additional offerings such as downloads and a shop linked to the official biogas.org site. The site maintains a consistent brand identity aligned with Fachverband Biogas and leverages social media for outreach. There is no evidence of direct revenue generation or complex business operations. The partnership ecosystem includes official biogas.org domains, reinforcing credibility. Growth potential lies in expanding educational content and improving digital presence.

Security posture

The current security posture is minimal. The website uses HTTPS (assumed from URL), but no security headers like Content-Security-Policy or X-Frame-Options are detected. There are no visible forms or inputs, reducing attack surface, but also no incident response or vulnerability disclosure information is provided. Privacy compliance is weak due to the absence of privacy and cookie policies. No analytics or tracking scripts are present, which limits privacy risks but also reduces insight into user behavior. The lack of contact information for security incidents is a gap. Overall, the site is low risk but would benefit from implementing standard security best practices and compliance documentation.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance security posture.
  3. Provide clear contact information including a dedicated security or abuse email address for incident response.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance technical SEO and accessibility features to improve site performance and user experience.

Technical notes

Notes

The website is built using modern JavaScript ES modules and CSS with SVG graphics for visual elements. It is hosted on servers indicated by the nameservers ns5.kasserver.com and ns6.kasserver.com, suggesting a German hosting provider. The site is mobile-optimized and has a clean, consistent design. There is no evidence of a CMS or third-party frameworks. Performance appears moderate with no heavy scripts or trackers detected. The site lacks advanced accessibility features and SEO optimizations beyond basic meta tags and Open Graph data. There is no evidence of analytics or marketing tools. Technical risks are low but the absence of security headers and policies represents a modernization opportunity.
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.
