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

      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';…

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 with a focus on integrated services from development to operation. Its business model revolves around providing comprehensive property-related services, leveraging digital tools and partnerships such as smart-construction.de. The website's content and linked domains suggest a mature market position with a medium to large company size. The absence of direct contact emails or phone numbers on the site indicates a preference for controlled communication via contact forms. The company maintains a professional digital presence with active social media engagement and a clear cookie consent strategy, supporting compliance and user trust.

Security posture

ZECH Bau SE demonstrates a moderate to strong security posture. The website uses HTTPS exclusively, employs a detailed cookie consent mechanism with GDPR compliance, and avoids exposing sensitive data. However, the absence of explicit security headers like Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerabilities or suspicious scripts were detected in the HTML content. The use of Matomo analytics with consent-based tracking reflects a privacy-aware approach. Overall, the security maturity is good but could be enhanced by formalizing security policies and adding security headers.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and readiness.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Add explicit company contact emails and phone numbers for improved user trust and communication.
  5. Regularly audit third-party scripts and tracking tools to ensure ongoing privacy compliance and security.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, combined with modern frontend libraries including jQuery, Bootstrap 4, and Owl Carousel for UI components. Analytics are handled by Matomo, configured for privacy with fingerprinting and no cookies by default. The site is mobile-optimized with responsive design and includes SEO-friendly meta tags and Open Graph data. Performance is moderate, with asynchronous loading of analytics scripts. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicitly disclosed. Overall, the technical infrastructure supports a professional and user-friendly web presence.
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.
