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

Mammut Sports Group AG is a well-established Swiss outdoor equipment and apparel company with a rich history dating back to 1862. The company operates a professional e-commerce platform targeting outdoor enthusiasts including hikers, climbers, skiers, and trail runners. The website reflects a mature digital presence with a modern tech stack based on Next.js and React, integrating advanced analytics and cookie consent management. Security posture is strong with HTTPS, security headers, and no visible vulnerabilities, although explicit security policies and incident response information are not published. The absence of WHOIS data is notable but does not detract from the overall trustworthiness given the brand's reputation and website professionalism. Strategic recommendations include publishing security and vulnerability disclosure policies and enhancing transparency on data retention.

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

4 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 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';…

  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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Mammut holds a strong market position as a premium Swiss brand in the outdoor retail sector. Its business model focuses on direct-to-consumer sales via its online shop, complemented by physical retail presence. The company targets active outdoor consumers seeking high-quality, performance-tested gear. Mammut benefits from brand heritage, athlete endorsements, and a broad product portfolio including clothing, footwear, and safety equipment. Partnerships such as the Mammut Mountain School enhance brand engagement. The company is part of Conzzeta AG, indicating solid corporate backing. Growth opportunities lie in expanding digital channels and sustainability initiatives.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected. However, the lack of published security policies, incident response contacts, or vulnerability disclosure programs indicates room for improvement in transparency and readiness. Compliance with GDPR is evident but could be strengthened by clearer data retention disclosures. Overall, the security posture is robust for an e-commerce retail site but would benefit from formalized security governance documentation.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting.
  3. Enhance transparency regarding data retention policies and user data handling.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Consider WHOIS record visibility improvements to enhance domain trust signals.

Technical notes

Notes

The website uses a modern JavaScript framework (Next.js) with React, enabling server-side rendering and good performance. Integration with Usercentrics provides GDPR-compliant cookie consent management. Analytics are handled via Exponea and Google Tag Manager, indicating a mature marketing stack. The site is mobile-optimized with responsive design and accessibility features. No CMS is explicitly identified but content delivery suggests a headless CMS, likely Contentful. Performance is moderate with potential for optimization in image delivery and script loading. Hosting provider details are not explicit. Overall, the technical infrastructure supports a high-quality user experience with scope for continuous improvement.
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.
