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 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"

  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

Thomann operates a large-scale retail e-commerce business focused on musical instruments and equipment. Its market position as Europe's largest music retailer is supported by extensive product categories and international reach. The business model centers on direct online sales with value-added services such as warranties and customer support. The company targets musicians and music enthusiasts across Europe and beyond. The website's multilingual and multi-currency support reflects a strategic approach to global markets. Trust indicators like satisfaction guarantees and payment security enhance customer confidence. The absence of direct contact emails or phone numbers in the HTML suggests reliance on contact forms and centralized customer service channels.

Security posture

The website maintains a good security baseline with HTTPS enforced and a cookie consent mechanism compliant with GDPR. Use of Google Tag Manager indicates tracking and marketing capabilities, balanced with privacy considerations. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options represents an area for improvement. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. CAPTCHA technology is implemented but currently disabled, which could be enabled to enhance protection against automated abuse. The absence of a published security policy or incident response contact limits transparency in security governance.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Enable CAPTCHA on login and critical forms to mitigate automated attacks and abuse.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  4. Consider adding direct verified contact emails and phone numbers for customer and security inquiries.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize tracking footprint.

Technical notes

Notes

The website uses a custom JavaScript framework with modular bootstrap components, SVG iconography, and asynchronous loading of Google Tag Manager scripts. The presence of multiple language and currency options indicates a robust internationalization infrastructure. Performance appears moderate with optimized images and responsive design. Accessibility features such as skip links and ARIA roles are implemented, enhancing usability. No CMS or hosting provider details are explicitly detected. The technical stack is modern but could benefit from enhanced security header configurations and active CAPTCHA enforcement to reduce risk.
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.
