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

Van Dorsten Makelaars is a well-established real estate agency operating primarily in Meppel and surrounding areas in the Netherlands. With over 50 years of experience, the company offers a comprehensive range of services including property sales, purchases, mortgages, appraisals, and insurance. The website reflects a professional and trustworthy business with a strong local presence and a large property portfolio. Technically, the site uses modern analytics tools such as Google Tag Manager and Inspectlet, and is well-optimized for mobile devices with good SEO practices. However, it lacks a cookie consent mechanism and some security headers, which are important for full GDPR compliance and security hardening. The domain registration data is consistent with the business claims, supporting legitimacy and trustworthiness.

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

8 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 holds a strong market position as a local leader in real estate services in Meppel, leveraging deep regional knowledge and a broad network. Their business model is full-service, targeting individuals and families looking to buy or sell homes, as well as mortgage and insurance services. The presence of partner domains such as woonaccentzwolle.nl and nexxtmove.nl indicates a collaborative ecosystem enhancing service delivery and digital presence. The company’s longevity and positive customer reviews further reinforce its credibility and growth potential.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposed sensitive data. However, the absence of DNSSEC, security headers, and a formal security policy or incident response contact reduces the overall security maturity. The use of third-party analytics and tracking tools without explicit cookie consent may pose compliance risks under GDPR. No critical vulnerabilities or malware indicators were detected, but improvements in security headers and privacy mechanisms are recommended to enhance protection and compliance.

Recommendations

  1. Implement a cookie consent banner to ensure GDPR compliance and inform users about tracking.
  2. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to harden the website against common attacks.
  4. Publish a dedicated security policy and provide incident response contact information to improve transparency and readiness.
  5. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website uses a clean and modern tech stack including Google Tag Manager, Inspectlet, and Nexxtmove Insights for analytics and user behavior tracking. The design is responsive and uses Google Fonts for typography. The site loads custom CSS and JavaScript efficiently, though performance is moderate rather than fast. SEO is well addressed with proper meta tags and structured navigation. There is no detected CMS or hosting provider information from the HTML content. The site could benefit from enhanced accessibility features and performance optimizations to improve user experience further.
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.
