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

5 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 business focused on musical instruments and related equipment, serving a broad European market with localized country sites. Their business model is primarily e-commerce driven, supported by extensive product categories and customer service offerings such as repair and warranty. The company leverages a network of partner domains for regional markets, enhancing reach and localization. Trust signals such as satisfaction guarantees and payment security are prominently featured, supporting strong market positioning. The absence of direct contact emails or phone numbers in the HTML suggests reliance on web forms and informational pages for customer interaction. The company appears well-established with a consistent brand presence across multiple domains.

Security posture

The website employs HTTPS and includes CAPTCHA for bot mitigation, alongside a comprehensive cookie consent mechanism indicating GDPR awareness. However, no explicit HTTP security headers (e.g., CSP, HSTS) were detected, which could improve protection against common web attacks. The use of third-party scripts like Google Tag Manager introduces a moderate tracking footprint, balanced by privacy policy transparency. The lack of visible incident response or vulnerability disclosure pages suggests room for improvement in security communication. Overall, the security posture is moderate with good privacy compliance but could benefit from enhanced technical security controls and transparency.

Recommendations

  1. Implement and enforce HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to strengthen web security.
  2. Publish a dedicated security policy and vulnerability disclosure program to improve transparency and incident response readiness.
  3. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance contact information availability by providing verified company emails and phone numbers for customer and security inquiries.
  5. Monitor domain registration status and consider clarifying WHOIS information to improve trust and legitimacy perception.

Technical notes

Notes

The website uses a custom JavaScript framework with modular bootstrap components and SVG iconography, ensuring a modern and responsive user interface. Google Tag Manager is integrated for analytics and marketing tracking. The site supports multiple languages and currencies, indicating a robust localization infrastructure. Performance appears moderate with optimized images and lazy loading for popups. Accessibility features such as skip links and ARIA roles are present, supporting inclusive design. However, the absence of detected CMS or hosting provider details limits full infrastructure assessment. Technical risks include missing security headers and reliance on third-party scripts without visible mitigation details.
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.
