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

Fensterfibel.de is an informational portal operated by BAKA Bundesverband Altbauerneuerung e.V., focusing on providing guidance and resources related to window and facade quality, renovation, and ventilation. The website targets planners, craftsmen, and building owners interested in energy-efficient building upgrades. It offers downloadable brochures, event announcements, and seminar information, positioning itself as a niche resource within the energy renovation sector in Germany. Technically, the site is built on the dev4u® CMS platform and uses legacy JavaScript libraries including jQuery 1.7.1, which introduces security concerns. Google Analytics is implemented with IP anonymization, but no cookie consent mechanism is present, indicating partial GDPR compliance. Security posture is moderate with no HTTPS or security headers data provided, and outdated libraries increase risk. WHOIS data is consistent and transparent, supporting legitimacy. Overall, the site is functional but requires modernization and improved security and privacy practices.

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. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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"

      • 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';…

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 portal serves a specialized market segment within the energy and building renovation industry, providing educational content and event information. Its business model revolves around information dissemination and community engagement rather than direct sales. Partnerships with organizations like BAKA and KfW indicate a credible ecosystem. The lack of direct contact emails or phone numbers suggests a low-touch engagement model, relying on contact forms. The site’s content quality and branding are consistent, supporting moderate trustworthiness. Growth opportunities include expanding digital presence and improving user engagement through enhanced technical and security features.

Security posture

The website demonstrates a basic security posture with the use of Google Analytics configured for IP anonymization. However, the presence of outdated JavaScript libraries such as jQuery 1.7.1 exposes the site to known vulnerabilities. No security headers were detected, and there is no evidence of HTTPS enforcement or advanced security policies. The absence of a cookie consent mechanism also indicates incomplete GDPR compliance. Incident response and security policy information are not provided, limiting transparency. Recommendations include updating all libraries, implementing security headers, enforcing HTTPS, and adding privacy compliance mechanisms to improve security maturity.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement and enforce HTTPS with strong SSL/TLS configurations to secure data in transit.
  3. Add comprehensive security headers such as Content Security Policy, X-Frame-Options, and HSTS to enhance protection.
  4. Introduce a cookie consent banner and improve privacy policy details to ensure GDPR compliance.
  5. Provide clear contact information including security incident response contacts to improve transparency and trust.

Technical notes

Notes

The website is built on the dev4u® CMS platform and uses several legacy JavaScript libraries including jQuery 1.7.1, jQuery BlockUI, Metadata, and Fancybox 1.3.0. Google Analytics is integrated via the older ga.js script with IP anonymization enabled. The site uses multiple CSS files for layout and print styles. The HTML content is served with charset ISO-8859-1, which may cause encoding issues as seen in meta tags. No modern frameworks or responsive design features are evident, indicating basic mobile optimization. Performance is moderate with no explicit speed optimizations detected. The site lacks accessibility features and advanced SEO optimizations. Overall, the technical stack is functional but outdated, posing risks and limiting user experience.
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.
