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

Wohnraumkarte GmbH is a German software company specializing in providing software solutions for the real estate industry, primarily through widgets and mapping tools integrated with OpenStreetMap and Mapbox. The website serves as a platform for property listings with filtering and mapping capabilities, targeting real estate professionals and clients in Germany. The business model is focused on Software as a Service (SaaS) offerings tailored to the real estate sector. Technically, the website employs modern JavaScript libraries such as Leaflet.js and Mapbox GL JS for interactive mapping, alongside jQuery and other UI libraries like Slick Carousel and PhotoSwipe. Hosting is managed via Amazon AWS infrastructure, as indicated by the DNS nameservers. The site demonstrates moderate performance and basic mobile optimization, with room for improvement in accessibility and SEO practices. From a security perspective, the site uses HTTPS and avoids exposing sensitive data in the HTML. However, it lacks visible security headers, privacy and cookie policies, and contact information for incident response, which are important for compliance and trust. No WAF or blocking mechanisms were detected, and no vulnerabilities were apparent in the provided content. Overall, the website is professionally designed and functional but would benefit from enhanced privacy compliance, security hardening, and clearer contact channels to improve trust and regulatory adherence.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

Wohnraumkarte GmbH occupies a niche position within the German real estate software market, offering specialized mapping and widget solutions for property listings. Its competitive advantage lies in integrating open mapping technologies with real estate data, providing value to agents and clients seeking interactive property search tools. The business model likely revolves around SaaS subscriptions or licensing of widgets to real estate companies. The absence of extensive marketing or social media presence suggests a focused, possibly B2B-oriented approach. Growth indicators and partnerships are not evident from the provided data, indicating a small to medium-sized enterprise with a localized market focus.

Security posture

The current security posture is moderate but incomplete. The use of HTTPS is a positive baseline, but the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. Lack of published privacy and cookie policies indicates potential GDPR compliance gaps. No incident response contacts or vulnerability disclosure mechanisms are present, limiting transparency and readiness. No vulnerable libraries were detected in the static content, but ongoing security assessments are recommended. Overall, the security culture appears basic and would benefit from formalized policies and technical enhancements.

Recommendations

  1. Publish comprehensive privacy and cookie policies to ensure GDPR compliance and user trust.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against web vulnerabilities.
  3. Provide clear contact information including security incident response channels to improve transparency and readiness.
  4. Enhance mobile optimization and accessibility to improve user experience and compliance with accessibility standards.
  5. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website leverages a modern JavaScript-based tech stack with Leaflet.js and Mapbox GL JS for interactive mapping, supported by jQuery and UI libraries like Slick Carousel and PhotoSwipe. Hosting on AWS provides scalable and reliable infrastructure. The site uses canonical URLs and Open Graph metadata for SEO and social sharing, though no JSON-LD structured data was found. Performance is moderate with basic mobile responsiveness. There is no detected CMS, suggesting a custom or static site architecture. Technical debt appears low but improvements in SEO, accessibility, and security headers would enhance overall quality and resilience.
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.
