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

Michel Bau is a German family-owned construction company specializing in high-rise, civil engineering, and environmental construction projects. The company positions itself as a specialist with experience, engagement, and modern technology, targeting clients across Germany. The website reflects a medium-sized business with a professional online presence, showcasing project stories and career opportunities. Technically, the site is built on WordPress using Elementor and Yoast SEO, with a cookie consent mechanism implemented via Borlabs Cookie and Google Tag Manager integration. Security posture is good with HTTPS enforced, but lacks some advanced security headers and explicit security policies. Privacy compliance is partial due to missing privacy and terms of service pages. Overall, the site is professional, trustworthy, and safe for general audiences.

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

9 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

Michel Bau operates in the real estate and construction sector, focusing on complex infrastructure, industrial buildings, and environmental projects. The business model is service-oriented, providing specialized construction services nationwide in Germany. The company leverages a family business reputation and emphasizes employee engagement and technical expertise. The website content targets business clients and potential employees, highlighting project case studies and career paths. The marketing ecosystem includes Google Tag Manager for analytics and Borlabs Cookie for consent management. No direct partnerships or subsidiaries were identified from the domain data.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and cookie consent mechanisms in place. However, there is an absence of explicit security policies, incident response contacts, and vulnerability disclosure information. No security headers were detected in the provided data, which could improve protection against common web attacks. The use of third-party plugins like Elementor and Borlabs Cookie requires regular updates to mitigate vulnerabilities. No exposed sensitive data or known vulnerabilities were found in the analysis. GDPR compliance is partial due to missing privacy policy documentation.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear contact information for security incidents, including dedicated security or abuse email addresses.
  5. Regularly audit and update all third-party plugins and scripts to minimize security risks.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building and Yoast SEO for search engine optimization. It employs jQuery and Swiper.js for interactive elements and Borlabs Cookie for GDPR-compliant cookie management. The site is mobile optimized with good accessibility and SEO practices. Performance is moderate, with potential improvements in caching and script optimization. Hosting provider details were not identified. The site uses Google Tag Manager for analytics and marketing tracking. Overall, the technical infrastructure supports a professional and functional web presence but could benefit from enhanced security configurations and performance tuning.
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.
