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. 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 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';…

  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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain shop.buersten.de points to unregistered service elb-front-92-16-397964034.eu-central-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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.

Dark web exposure

Add-on

Leaked records that mention buersten.de, from OffSeq Breach.

No leaked records found

Breach holds no records for buersten.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 company maintains a focused market position as a manufacturer and supplier of cleaning tools, serving a specialized sector within manufacturing and retail. Its direct-to-factory production approach suggests control over product quality and supply chain. The website's integration with advertising and affiliate networks like Google Ads and ADCELL indicates active marketing efforts to reach target audiences. The absence of phone contact but presence of email and account login forms suggests a digital-first customer engagement strategy. No parent or subsidiary companies are identified, indicating an independent small business. The company’s digital ecosystem is supported by established third-party services, enhancing its operational capabilities and market reach.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and the use of Google reCAPTCHA to mitigate spam and abuse. Consent management for cookies and tracking is implemented in compliance with GDPR, reflecting awareness of privacy and security regulations. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact limits transparency in security governance. Overall, the site is secure for typical e-commerce operations but could benefit from formalizing and communicating its security framework and incident response procedures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated contact channels for incident reporting and vulnerability disclosure to improve transparency and trust.
  3. Regularly audit and update all third-party libraries and plugins to mitigate risks from known vulnerabilities.
  4. Enhance contact information by including verified company phone numbers to improve customer trust and support accessibility.
  5. Consider creating and publishing a security.txt file to facilitate responsible vulnerability disclosure and improve security posture.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, Bootstrap, and integrates Google services for analytics and advertising. The CMS appears to be JTL Shop, a specialized e-commerce platform, which supports structured data and SEO best practices. Performance is moderate with good mobile optimization and accessibility features. The site uses deferred and asynchronous loading for scripts and stylesheets to improve load times. However, there is no explicit evidence of advanced performance optimization techniques such as CDN usage or image optimization beyond standard responsive images. The technical infrastructure supports a professional and functional e-commerce experience but could be enhanced with additional security headers and performance tuning.
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.
