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

Bayern Fernwärme is a small German company specializing in the insulation and re-insulation of district heating pipelines, operating primarily in Donaueschingen. The website presents a professional image with clear business descriptions and contact information, targeting property owners and businesses interested in cost-effective heating solutions. The company positions itself as a reliable local service provider with a focus on customer consultation and quality service. Technically, the website is built on the IONOS MyWebsite platform, utilizing standard web technologies such as HTML, CSS, and JavaScript. The site is moderately optimized for performance and mobile devices but lacks advanced SEO and accessibility features. No advanced frameworks or analytics tools are detected, indicating a basic digital maturity level. From a security perspective, the site uses HTTPS but lacks important security headers and policies such as privacy and cookie notices, which are critical for GDPR compliance. The absence of WHOIS registration data raises concerns about domain legitimacy and ownership transparency. No forms or data collection mechanisms are present, reducing immediate data protection risks but also limiting user engagement. Overall, the website is functional and professional but requires improvements in compliance, security best practices, and domain registration transparency to enhance trust and reduce risk.

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

7 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 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

    • 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

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

Bayern Fernwärme operates in the energy sector with a niche focus on district heating insulation services. Its business model revolves around providing specialized services including planning, consultation, and implementation of insulation solutions. The company targets local customers in Germany, particularly in Donaueschingen, positioning itself as a trusted partner for cost-effective heating alternatives. The website content and metadata suggest a small-sized enterprise with no visible parent or subsidiary relationships. The lack of social media presence and limited digital marketing tools indicate a traditional business approach with potential growth opportunities through enhanced online engagement and partnerships.

Security posture

The current security posture of the website is basic. HTTPS is enabled, ensuring encrypted communication, but the absence of critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No privacy or cookie policies are present, indicating non-compliance with GDPR and other data protection regulations. The lack of incident response contacts or vulnerability disclosure mechanisms further limits the site's security readiness. Additionally, the missing WHOIS data undermines domain ownership transparency, which is a key trust factor. Overall, the site requires significant improvements in security policies, compliance documentation, and technical safeguards to meet modern standards.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against web vulnerabilities.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement a cookie consent mechanism.
  3. Verify and update domain registration details to ensure WHOIS data is complete and accurate, improving legitimacy and trust.
  4. Establish an incident response contact channel and consider publishing a vulnerability disclosure policy to improve security transparency.
  5. Enhance website accessibility and SEO features to improve user experience and search engine visibility.

Technical notes

Notes

The website is hosted on the IONOS MyWebsite platform, leveraging standard web technologies such as HTML5, CSS, and JavaScript. The site uses CDN services from website-start.de and related subdomains for resource delivery. Performance is moderate with basic mobile optimization and responsive design. However, the site lacks advanced frameworks or modern JavaScript libraries, indicating limited technical complexity. SEO optimization is basic with meta tags and Open Graph data present but no structured data like JSON-LD. Accessibility features are minimal, and no analytics or tracking scripts are detected beyond platform essentials. The technical infrastructure is stable but could benefit from modernization and enhanced compliance features.
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.
