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

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 business operates as a small regional service provider within the energy and home improvement sectors, focusing on bathroom and heating installations and renovations. Its competitive advantages include comprehensive customer support from planning to completion, fixed pricing, and a single point of contact. The affiliation with SHK eG enhances credibility and market reach. Revenue streams likely derive from service contracts, renovations, and heating system installations. The target customers are residential clients and possibly small commercial properties. The partnership ecosystem includes the die-badgestalter.de platform and the Koch Haustechnik GmbH official site. Growth indicators include active content marketing via inspiration articles and social media engagement. Strategic observations suggest maintaining strong local presence and expanding digital marketing efforts.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, and cookie consent mechanisms comply with GDPR, including anonymization of IP addresses in analytics. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The site does not provide explicit incident response contacts or vulnerability disclosure information, which could be enhanced to improve security culture and transparency. Overall, the security posture is adequate for the business size and sector but could benefit from formalized policies and technical hardening.

Recommendations

  1. Implement HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Expand digital marketing and SEO efforts to strengthen market position and customer acquisition.

Technical notes

Notes

The website is built on the TYPO3 CMS platform, indicating a mature and scalable content management system. It uses Matomo analytics for privacy-conscious user tracking and Google Maps API for location services. The presence of promise-polyfill and systemjs scripts suggests compatibility with older browsers and modular JavaScript loading. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with potential improvements in loading speed by optimizing assets and leveraging caching. The technical stack is modern but could benefit from enhanced security headers and accessibility improvements. Hosting appears to be managed via generic German hosting providers as indicated by the nameservers.
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.
