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

Müller Handels GmbH & Co. KG operates a large retail and e-commerce platform primarily serving the German market and neighboring German-speaking countries. The company offers a wide range of products including perfumes, cosmetics, toys, multimedia, and household goods, positioning itself as a comprehensive drugstore and lifestyle retailer. The website is professionally designed with excellent content quality, clear navigation, and strong branding consistency, targeting general consumers with a focus on convenience and variety. Technically, the website leverages modern web technologies such as Next.js and React, combined with Usercentrics for cookie consent management and Google Tag Manager and Facebook Pixel for analytics and marketing. The platform is mobile-optimized and performs moderately well, with good SEO and accessibility features. Hosting details are not explicitly disclosed, but the infrastructure supports a robust e-commerce experience. From a security perspective, the site enforces HTTPS and integrates consent mechanisms for privacy compliance. While explicit security headers and policies are not fully visible, no critical vulnerabilities or exposed sensitive data were detected. The absence of a published security policy or vulnerability disclosure page suggests room for improvement in transparency and incident response readiness. Overall, the website presents a low-risk profile with strong business credibility and compliance posture. Strategic recommendations include publishing comprehensive privacy and security policies, enhancing security header implementation, and providing clear incident response contacts to further strengthen trust 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

1 finding rated critical or high. Fix these first.

  1. 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

      • ASVS V12.1.1

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

Müller is a well-established retail chain with a significant online presence, competing in the drugstore and lifestyle retail sector. Its business model combines physical stores with e-commerce, offering a broad product assortment to a wide consumer base. The company benefits from strong brand recognition, a diversified product portfolio, and loyalty programs such as BabyClub. Its market position is reinforced by consistent branding and a professional digital presence. The company leverages partnerships with major brands and maintains active social media channels to engage customers. Growth indicators include continuous product updates and online exclusives. The absence of parent or subsidiary domain mentions suggests a focused brand strategy without complex corporate layering.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and integration of a consent management platform to comply with GDPR. No critical security issues or vulnerabilities were identified in the visible content. However, the lack of explicit security headers and absence of a public security policy or vulnerability disclosure mechanism indicate potential gaps in security transparency and incident readiness. The use of third-party scripts for analytics and marketing is standard but requires ongoing monitoring to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by formalizing policies and improving header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and explicitly declare security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide clear contact information for a Data Protection Officer or security incident response team.
  5. Regularly audit third-party scripts and tracking technologies to minimize privacy and security risks.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) enabling server-side rendering and optimized performance. It uses Usercentrics for GDPR-compliant cookie consent management and integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is mobile-optimized with responsive design and accessible navigation. Performance is moderate, likely due to the extensive use of images and third-party scripts. No CMS is explicitly detected, suggesting a custom or proprietary content management solution. Hosting details are not disclosed, but the domain uses multiple name servers indicating a stable DNS setup. Opportunities exist to improve technical SEO and security header implementation to reduce technical debt and enhance resilience.
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.
