0–100, higher is better. How it is calculated

Thomann is a leading European e-commerce retailer specializing in musical instruments, accessories, and related equipment. The website targets primarily the Norwegian market, offering a wide range of products including guitars, drums, studio equipment, and software. The company positions itself as Europe's largest music retailer, providing extensive services such as repair, customer support, and a mobile app. The business model is focused on online retail with a strong emphasis on customer satisfaction and trust, supported by guarantees and warranties. Technically, the website employs modern web technologies including JavaScript frameworks, Google Tag Manager for analytics, and Turnstile CAPTCHA for security. The site is well-optimized for mobile devices and accessibility, with comprehensive SEO metadata and structured data. Performance is moderate, with room for improvement in loading speed and security headers. From a security perspective, the site uses HTTPS and has implemented cookie consent mechanisms aligned with GDPR requirements. However, explicit security headers are not detected, and there is no publicly available security policy or incident response information. No vulnerabilities or suspicious activities were identified in the content or scripts. Overall, the website presents a professional, trustworthy, and user-friendly platform with strong privacy compliance. The lack of WHOIS data is consistent with .no domain policies and does not detract from the legitimacy of the business. Strategic recommendations include enhancing security headers, publishing security policies, and establishing a vulnerability disclosure program to further strengthen trust and security posture.

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

7 findings rated critical or high. Fix these first.

  1. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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. 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

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 holds a strong market position as Europe's largest music retailer, targeting musicians and music enthusiasts primarily in Norway and Europe. The company leverages a comprehensive e-commerce platform offering a broad product catalog and value-added services such as repair and customer support. Revenue streams likely include direct product sales and possibly affiliate marketing. The business ecosystem includes multiple country-specific domains and localized content, indicating a mature international presence. The company emphasizes customer trust through guarantees and warranties, which are key competitive advantages. Growth indicators include a robust digital presence, mobile app availability, and active marketing via newsletters and promotions.

Security posture

The security maturity level of the website is moderate to good. HTTPS is enforced, and CAPTCHA mechanisms protect login forms, reducing automated abuse risks. Cookie consent and privacy policies demonstrate GDPR compliance. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure information is publicly available, which could hinder rapid response to security events. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture supports business continuity but would benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a detailed security policy and incident response plan accessible to users and stakeholders.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance transparency by providing contact channels for security incidents such as security@ or abuse@ email addresses.
  5. Optimize website performance and loading speed to improve user experience and reduce potential attack surface.

Technical notes

Notes

The website uses a custom JavaScript framework with modular bootstrap components, Google Tag Manager for analytics, and Turnstile CAPTCHA for bot protection. The presence of JSON-LD structured data and comprehensive meta tags supports SEO and rich search results. The site is mobile-optimized and accessible, with clear navigation and consistent branding. Performance is moderate, with potential improvements in resource loading and caching. Hosting provider details are not explicitly identified. The absence of a known CMS suggests a custom-built platform. Technical risks include missing security headers and potential reliance on third-party scripts which should be regularly audited.
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.
