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

8 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

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 with a focus on musical instruments and related equipment. Its market position as Europe's largest music retailer is supported by extensive product categories and strong customer service guarantees such as money-back and warranty policies. The business model is direct online sales supported by a large European distribution center. The target customers are musicians, studios, and event professionals. The company maintains multiple country-specific domains, indicating a broad geographic reach. The website content and structure reflect a mature digital presence with strong branding consistency and trust signals. No suspicious or privacy-protected WHOIS data is present, reinforcing legitimacy. The company benefits from a robust partnership ecosystem and a well-established brand reputation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and modern security headers likely in place. The use of Cloudflare Turnstile CAPTCHA enhances protection against automated abuse. Cookie consent mechanisms comply with GDPR requirements, and login forms include CAPTCHA fallback for security. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information represents a gap in transparency and readiness. No public vulnerability disclosure or security.txt file was found, which could be improved to foster responsible vulnerability reporting. Overall, the security posture is strong but could benefit from enhanced communication of security policies and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user privacy practices.
  5. Continue monitoring and updating third-party libraries and frameworks to mitigate vulnerabilities.

Technical notes

Notes

The website uses a custom JavaScript framework with modular bootstrap components, SVG icons, and JSON-LD structured data for SEO. Google Tag Manager is integrated for analytics and marketing. The site is optimized for desktop and mobile with responsive design and accessibility features. Performance is fast with efficient image loading and asynchronous script loading. The CMS appears custom-built, supporting multiple country and language variants. No technical debt or deprecated technologies were detected in the HTML content. Hosting provider details are not explicit but the infrastructure supports HTTPS and modern security features. Opportunities exist to improve technical documentation around security and privacy compliance.
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.
