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

Mammut is a well-established Swiss outdoor brand specializing in high-quality outdoor clothing, footwear, and equipment for activities such as hiking, climbing, skiing, and trail running. The website serves as an official e-commerce platform targeting outdoor enthusiasts and athletes, offering a broad product range and curated collections. The brand emphasizes Swiss design heritage dating back to 1862, positioning itself as a premium player in the outdoor retail market. Technically, the website is built on modern web technologies including Next.js and React, ensuring fast performance and excellent mobile optimization. It integrates consent management via Usercentrics and uses Google Tag Manager for analytics, reflecting a mature digital infrastructure. The site is well-structured with comprehensive metadata, structured data, and SEO best practices. From a security perspective, the site enforces HTTPS, implements multiple security headers, and manages user consent effectively. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of WHOIS registration details is notable and should be monitored, though it does not currently detract from the site's legitimacy. Overall, Mammut's website demonstrates a strong security posture, excellent user experience, and compliance with privacy regulations. Strategic recommendations include publishing explicit security and incident response policies, enhancing accessibility, and maintaining vigilance on third-party library updates to sustain security and compliance.

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 operates in the retail sector with a focus on outdoor apparel and equipment. Its competitive advantage lies in its long heritage, Swiss design quality, and athlete-tested products. The business model centers on direct-to-consumer e-commerce complemented by physical retail presence. Revenue streams include product sales across multiple categories such as clothing, footwear, and specialized equipment. The target customer segments are outdoor enthusiasts, athletes, and adventure travelers. Growth indicators include active marketing campaigns, loyalty programs, and collaborations with designers. The partnership ecosystem includes specialized mountain schools and B2B portals. The company maintains a strong brand presence and consistent messaging across its digital channels.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and consent management mechanisms. No signs of malware, phishing, or exposed credentials were found. GDPR compliance is evident through privacy and cookie policies and user consent tools. However, the absence of a dedicated security policy or vulnerability disclosure page suggests room for improvement in transparency and incident response readiness. The site does not publicly list a data protection officer or incident response contacts, which could enhance trust and compliance. Overall, the security culture appears proactive but could benefit from formalized documentation and communication.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program and security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet or exceed WCAG standards for broader user inclusivity.
  5. Maintain ongoing GDPR compliance audits and update privacy practices as regulations evolve.

Technical notes

Notes

The website leverages a modern tech stack with React and Next.js, enabling server-side rendering and optimized performance. Integration of Usercentrics for consent management and Google Tag Manager for analytics indicates a sophisticated approach to privacy and data collection. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well-implemented with structured data and meta tags. No CMS was explicitly detected, suggesting a custom or proprietary solution. Hosting provider details were not identified. Performance is fast with efficient resource loading. Technical risks are minimal but include the need for continuous dependency management and potential improvements in accessibility.
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.
