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

BauNetz Maps is a well-established interactive platform dedicated to showcasing contemporary architecture projects worldwide. Operated by Heinze GmbH, a subsidiary of Infopro Digital, the platform aggregates over 10,000 architectural projects and related content from multiple BauNetz services, including news, architect profiles, and educational resources. The website targets a broad audience interested in architecture, including professionals and enthusiasts, and offers additional services such as job listings in the architecture and construction sectors. Technically, the website employs modern web technologies including JavaScript frameworks (likely Vue.js), Google Maps API for geolocation and mapping, and Cloudflare CDN for performance and security. Consent management and analytics are handled via ConsentManager and Webtrekk respectively, ensuring compliance with privacy regulations. The site is mobile-optimized and demonstrates good SEO and accessibility practices, though some accessibility improvements could be made. From a security perspective, the site enforces HTTPS and uses Cloudflare for DDoS protection and content delivery. Cookie consent mechanisms are implemented, and no critical vulnerabilities or exposed sensitive data were detected. However, explicit security headers could be enhanced, and the site lacks a public incident response or vulnerability disclosure policy. Overall, BauNetz Maps presents a professional, trustworthy, and content-rich platform with strong business credibility and compliance posture. Strategic improvements in security headers and incident response transparency would further strengthen its security maturity.

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

BauNetz Maps holds a strong market position as a niche architecture media platform with a comprehensive database of projects and related content. Its business model revolves around content aggregation, publishing, and providing value-added services such as job listings and architect profiles. The platform benefits from its parent company Infopro Digital's backing, ensuring stability and resources. Its target customers include architects, designers, researchers, and architecture enthusiasts globally, with a focus on German-speaking markets. The partnership ecosystem includes multiple BauNetz branded sites and related architecture portals, enhancing its reach and content diversity. Growth indicators include extensive project data and integration of job market services. The company maintains a consistent brand and leverages CO2-neutral certification as a trust and sustainability signal.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and Cloudflare CDN providing network-level protections. Cookie consent and privacy policies are comprehensive and GDPR compliant. Use of third-party analytics and consent tools is transparent with opt-out options. No critical vulnerabilities or exposed sensitive data were found in the HTML content. However, the absence of explicit security headers like X-Frame-Options and a public incident response or vulnerability disclosure policy indicates room for improvement. The site does not appear to have dedicated security contact channels, which could hinder rapid incident response. Overall, the security culture appears adequate for the business type but could be enhanced by formalizing incident response and vulnerability management processes.

Recommendations

  1. Implement and verify comprehensive security headers including X-Frame-Options and X-Content-Type-Options to mitigate clickjacking and MIME sniffing risks.
  2. Publish a clear incident response and vulnerability disclosure policy with dedicated security contact information to improve transparency and readiness.
  3. Conduct regular security audits of third-party scripts and dependencies to prevent supply chain vulnerabilities.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.
  5. Maintain and communicate data retention policies clearly, especially for analytics and logs, to reinforce privacy compliance.

Technical notes

Notes

The website uses a modern JavaScript framework (likely Vue.js) combined with Google Maps API for interactive mapping features. Cloudflare CDN is employed for performance optimization and security. ConsentManager handles cookie consent management, ensuring GDPR compliance. Webtrekk provides analytics with opt-out capabilities. The site is mobile-optimized and includes SEO best practices such as meta tags and Open Graph data. No major technical debt or deprecated technologies were detected. Performance is moderate, with potential for improvement in load times and accessibility. The absence of a known CMS suggests a custom or proprietary solution, which may require dedicated maintenance resources.
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.
