DatHuis is a Dutch company specializing in marketing products and lead generation platforms tailored for real estate professionals. The website positions itself as an all-in-one solution for lead generation and cross-selling within the real estate sector, targeting professionals in the Netherlands. The business model is B2B, focusing on providing digital marketing tools and services to enhance client acquisition and retention for real estate agents and related professionals. The company was founded in 2016, consistent with the domain registration date, and operates with a small-sized business profile. Technically, the website is built on WordPress with a modern tech stack including HubSpot marketing tools, Cookiebot for cookie consent, Chargebee for payment processing, and Intercom for customer engagement. The site is well-optimized for SEO with Yoast SEO plugin and includes structured data for enhanced search engine understanding. Performance is moderate with good mobile optimization and basic accessibility features. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks DNSSEC and explicit security headers. Cookie consent is properly implemented, indicating awareness of privacy compliance, although no explicit privacy policy or terms of service pages were detected in the provided content. No direct contact or incident response information is available, which could be improved to enhance trust and compliance. Overall, the website presents a professional and trustworthy front for its target audience, with strong marketing and analytics integration. Recommendations include enabling DNSSEC, adding security headers, publishing privacy and security policies, and providing clear contact information for security and business inquiries to strengthen compliance and security posture.

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

3 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 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

DatHuis operates in the Dutch real estate marketing sector, offering specialized lead generation and cross-selling platforms. Its competitive advantage lies in integrating multiple marketing tools and analytics services to provide a comprehensive solution for real estate professionals. The business model is subscription or service-based, supported by Chargebee payment integration. The target customers are real estate agents and agencies seeking to improve their marketing effectiveness. The company leverages partnerships with HubSpot, Cookiebot, and Intercom to enhance its service offerings. Growth indicators include active use of advanced marketing technologies and a domain age of over 7 years, suggesting established market presence. The lack of visible contact information and formal policies may limit trust for some clients but does not detract from the technical sophistication of the platform.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent mechanisms in place. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable third-party services like HubSpot and Chargebee suggests reliance on their security frameworks. The lack of a published security policy or incident response contact reduces transparency and readiness for security incidents. Compliance with GDPR is partially indicated by cookie consent but lacks explicit privacy policy documentation. Overall, the security posture is adequate for a marketing platform but should be enhanced to meet higher compliance and trust standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and make accessible a comprehensive privacy policy and terms of service page.
  4. Provide clear contact information including security incident response and data protection officer contacts.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a WordPress CMS platform with a modern and well-integrated technology stack including HubSpot for marketing automation, Cookiebot for GDPR-compliant cookie management, Chargebee for subscription billing, and Intercom for customer support chat. The site uses jQuery and SVG support plugins, and is optimized with Yoast SEO for search engine visibility. Performance is moderate with good mobile responsiveness and basic accessibility features. The site loads multiple external scripts from trusted domains, indicating a mature digital infrastructure. However, there is no evidence of advanced security headers or DNSSEC, which are recommended for technical hardening. The domain is registered with a reputable Dutch registrar, consistent with the business location and language.
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.
