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

GrünKonzept Flensburg GmbH is a medium-sized local business specializing in garden and landscape construction, garden maintenance, and garden technology services in the Flensburg region of Germany. The company targets both private and public garden owners, offering a range of services including garden construction, robotic lawn mowers, lighting, and irrigation systems. The website is professionally designed using TYPO3 CMS and integrates modern marketing tools such as Google Ads and Tag Manager. Contact information is clearly provided, and social media presence on Facebook and Instagram supports customer engagement. However, the site lacks explicit privacy and cookie policies, which may impact GDPR compliance. Security posture is adequate with HTTPS enabled but could be improved by adding security headers and incident response information. Overall, the website presents a trustworthy and professional image with room for enhanced privacy and security 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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

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

The company holds a strong local market position as a trusted expert in garden and landscape services with over 18 years of experience. Its business model focuses on service provision to both private and public sectors, leveraging a diversified portfolio including garden construction, maintenance subscriptions, and garden technology products. The presence of a dedicated subdomain for Nordic Fence suggests product line specialization or partnership. Marketing efforts include Google Ads and social media engagement. The company appears to have a stable operational structure with clear departmental roles and a medium-sized team. No parent or subsidiary companies are indicated. The website content and branding are consistent and support a credible business image.

Security posture

The website employs HTTPS and integrates Google Tag Manager for analytics and conversion tracking, indicating a baseline security awareness. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No incident response or vulnerability disclosure information is provided, limiting transparency for security issues. Forms appear to be standard with no visible sensitive data exposure. No known vulnerable libraries or scripts were detected. The security score is moderate, with recommendations to implement security headers, publish a security.txt file, and provide incident response contacts to improve trust and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR-compliant consent mechanisms.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish a security.txt file and provide clear incident response contact information to improve security transparency.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features and conduct periodic SEO audits to maintain and improve website performance and user experience.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a mature technical infrastructure. It uses Google Tag Manager and Google Ads for marketing and analytics, and Elfsight widgets for customer reviews integration. Hosting is managed via DomainControl nameservers, likely GoDaddy. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate with compressed CSS and lazy loading images. Accessibility is basic but could be improved. SEO is supported by meta tags, structured data (JSON-LD with LocalBusiness schema), and canonical links. No critical technical debt or outdated technologies were detected, but security enhancements are recommended.
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.
