Risk levelMedium

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

Rinn Beton- und Naturstein GmbH is a German company specializing in concrete and natural stone products for garden and property landscaping, with a history spanning over 100 years. The website presents a professional and well-structured digital presence using TYPO3 CMS, featuring comprehensive product information and a clear focus on quality and sustainability. The company targets garden owners, landscapers, and construction professionals, positioning itself as a trusted provider in the landscaping materials sector. Technically, the website employs modern web technologies including Cookiebot for consent management and Google Tag Manager for analytics, ensuring compliance with GDPR and related privacy regulations. However, the absence of WHOIS registration data raises concerns about domain legitimacy, despite the professional appearance and content quality of the site. Security measures such as HTTPS are implied but security headers and incident response policies are not explicitly found, indicating room for improvement in security posture. Overall, the website is functional, compliant, and trustworthy from a user perspective but requires verification of domain registration and enhancement of security policies to strengthen its risk profile.

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 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

      • CWE-327
      • OWASP A04:2025
      • 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

The company operates in the Real Estate sector, specifically in manufacturing and retail of garden concrete products. Its business model focuses on providing high-quality, sustainable landscaping materials to a medium-sized market in Germany. The website reflects a mature digital marketing strategy with integrated analytics and advertising tools from major providers like Google and Meta Platforms. The lack of explicit contact information and WHOIS data suggests potential gaps in transparency that could affect customer trust. The company appears to have a stable market position with a long history, but no parent or subsidiary relationships were identified. The use of Cookiebot and GDPR-compliant privacy policies indicates awareness of regulatory requirements. Strategic partnerships or related domains were not detected in the provided data.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and cookie consent mechanisms in place. However, the absence of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security score. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The lack of a published security policy, incident response contact, or vulnerability disclosure program limits the organization's readiness to handle security incidents. The use of third-party tracking and advertising services introduces privacy considerations that are mitigated by the consent banner. Recommendations include implementing comprehensive security headers, publishing incident response information, and verifying SSL/TLS configurations to enhance security posture.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to protect against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  3. Verify and strengthen SSL/TLS configuration to ensure robust encryption and trust.
  4. Add explicit contact information including company emails and phone numbers to enhance business credibility.
  5. Consider publishing a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a solid technical foundation. It uses modern front-end libraries such as Owl Carousel and integrates Cookiebot for GDPR-compliant cookie management. Google Tag Manager is employed for analytics and marketing tracking, reflecting a mature digital marketing infrastructure. Performance appears moderate with preloading of fonts and compressed CSS/JS assets. Mobile optimization is good, with responsive meta tags and viewport settings. Accessibility features are basic but present. SEO is supported by meta descriptions, canonical links, and structured data in JSON-LD format. Hosting provider details were not identified. Overall, the technical implementation supports a professional and user-friendly website experience but could benefit from enhanced security configurations and accessibility improvements.
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.
