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

Benner Holding is a well-established German family-owned holding company founded in 1882, with diversified business interests spanning real estate, trade, agriculture, energy, and hospitality sectors. The company emphasizes long-term investments and diversification to maintain stability even during economic downturns. The website reflects a professional corporate presence with clear business sector segmentation and leadership visibility, notably CEO Dr. Dominik Benner. Technically, the site is built on WordPress using Elementor and Yoast SEO, indicating a modern and maintainable infrastructure. The site is mobile-optimized and SEO-friendly but lacks some advanced accessibility features. Security posture is adequate with HTTPS enabled and domain transfer protection, but lacks DNSSEC and security headers, and no explicit security or incident response policies are published. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the site is trustworthy and professional but could improve in security and privacy 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

6 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
      • 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

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

Benner Holding operates as a medium-sized diversified family business with a strong legacy and market presence in Germany. Its business model focuses on broad sector diversification to mitigate risks and capitalize on multiple revenue streams. The company targets general audiences including investors, tenants, and partners across real estate, trade, agriculture, and hospitality. The website's navigation and content structure support clear communication of its business units and strategic goals. The partnership with p5.immo suggests active engagement in real estate industry events. The absence of detailed financial or certification information limits deeper business intelligence insights but the long history and visible leadership indicate stability and growth orientation.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and domain transfer protection status set. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or security policy information is publicly available, which could hinder transparency and trust. No forms or input fields on the homepage reduce attack surface, but the overall security maturity appears moderate. The site uses common WordPress plugins and themes, which require regular updates to avoid vulnerabilities. No analytics or tracking scripts were detected, reducing privacy risks but also limiting behavioral insights.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Content-Type-Options, X-Frame-Options) to mitigate common web attacks.
  3. Add a cookie consent banner/mechanism to comply with GDPR and improve privacy transparency.
  4. Publish a clear security policy and incident response contact information to build trust and readiness.
  5. Regularly audit and update WordPress core, themes, and plugins to minimize vulnerability exposure.

Technical notes

Notes

The website is built on a modern WordPress platform using Elementor page builder and Yoast SEO plugin, indicating good CMS choice for flexibility and SEO. The site loads moderate resources including jQuery and Swiper.js for UI components. Performance is moderate with no explicit speed optimizations detected but mobile responsiveness is good. Accessibility is basic with some ARIA attributes and skip links present but no advanced features. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Hosting appears to be with IONOS SE, a reputable provider. No advanced analytics or marketing tools are detected, suggesting a focus on corporate presence rather than aggressive marketing.
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.
