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

Denns BioMärkte operates as a large-scale organic retail chain in Germany, offering a comprehensive range of organic products including food, fresh produce, bakery items, ecological drugstore goods, and natural cosmetics. The company is part of the BioMarkt Verbund, a recognized network of organic markets, and emphasizes certified organic products from reputable associations such as Bioland, Biokreis, Naturland, and Demeter. The website reflects a professional retail business model targeting general consumers interested in organic and ecological products. Technically, the website is built using modern frameworks like React and Gatsby, hosted on Microsoft Azure DNS infrastructure, and incorporates essential marketing and tracking tools such as Google Tag Manager and Facebook Pixel. The site includes a cookie consent mechanism via Cookiebot, indicating compliance efforts with GDPR regulations. Security-wise, while HTTPS is implied and cookie consent is implemented, the site lacks visible advanced security headers and formal security policies or incident response contacts. No blocking or WAF challenges were detected, allowing full content access. Overall, the website demonstrates a good balance of business credibility, technical implementation, and privacy compliance, with room for improvement in security policies and transparency.

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

3 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"

    • 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

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

Denns BioMärkte holds a strong position in the German organic retail sector, leveraging certifications from leading organic associations to build trust and brand recognition. The business model focuses on providing a wide assortment of organic products for daily needs, appealing to environmentally conscious consumers. The company benefits from being part of the BioMarkt Verbund, enhancing its market reach and credibility. The website's content quality and branding consistency support a professional image, while the use of modern web technologies suggests a commitment to digital maturity. However, the absence of explicit contact information and detailed corporate data on the website limits direct customer engagement and transparency. The presence of tracking and marketing tools indicates active customer analytics and retargeting strategies, aligned with typical retail marketing practices.

Security posture

The website employs HTTPS and integrates a cookie consent mechanism, reflecting baseline security and privacy compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No vulnerability disclosure or security.txt files were found, and no incident response contacts are provided, which could hinder effective communication in case of security incidents. The use of third-party tracking scripts introduces potential privacy risks if not properly managed. Overall, the security maturity is moderate, with key areas for enhancement including formal security policies, improved header configurations, and transparent incident response mechanisms.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a clear privacy policy and terms of service pages accessible from the website footer or main navigation.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide explicit contact information including emails and phone numbers for customer support and security incident reporting.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize data exposure.

Technical notes

Notes

The website is built on a modern React and Gatsby stack, leveraging Tailwind CSS for styling, which supports responsive and performant front-end delivery. Hosting on Microsoft Azure DNS indicates reliable infrastructure. The site includes integration with Cookiebot for consent management and uses Google Tag Manager and Facebook Pixel for analytics and marketing. The HTML structure and meta tags support good SEO practices. However, accessibility features appear basic and could be improved for better inclusivity. Performance is moderate, with potential optimization opportunities in script loading and asset management. The absence of visible security headers and formal security documentation suggests technical debt in security hardening. Overall, the technical implementation is solid but can benefit from focused improvements in security and 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.
