Risk levelLow

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

Eerlijk Bieden is a Dutch company operating in the real estate sector, providing an independent certification mark for real estate agents to guarantee a fair bidding process for consumers. Founded in 2021, it positions itself as the first fully independent quality mark for real estate agents in the Netherlands. The website is built on WordPress using modern tools such as Elementor and Astra theme, with good SEO practices including structured data and social media integration. The technical infrastructure is supported by a reputable registrar with DNSSEC enabled and HTTPS enforced, indicating a secure baseline. However, the site lacks visible privacy and cookie policies, incident response information, and security headers, which are important for compliance and security maturity. Overall, the website is professional and trustworthy but could improve its privacy 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 targets consumers looking for trustworthy real estate agents by offering a certification that guarantees an honest bidding process. Its business model revolves around providing an independent quality mark, which can enhance market trust and differentiate certified agents. The website's content and metadata reflect a clear focus on this niche, with social media presence on Facebook and Twitter supporting marketing efforts. The domain age and WHOIS data align with the company's founding date, supporting legitimacy. The absence of detailed contact information and policies suggests room for growth in transparency and customer engagement. There are no indications of partnerships or subsidiaries from the provided data.

Security posture

The website benefits from HTTPS and DNSSEC, which are strong security indicators. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces its defense-in-depth. No vulnerability disclosures or incident response contacts are published, which limits the ability to handle security incidents effectively. The absence of privacy and cookie policies also raises compliance concerns, especially under GDPR. No exposed sensitive data or vulnerable libraries were detected in the provided content. The overall security posture is moderate but could be significantly improved by implementing recommended security best practices and compliance documentation.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance and consent mechanisms.
  2. Implement and configure security headers to enhance protection against common web attacks.
  3. Add a security.txt file and incident response contact information to improve vulnerability management.
  4. Provide clear and verified contact information including emails and phone numbers for customer and security inquiries.
  5. Regularly audit and update the technology stack and plugins to avoid vulnerabilities and improve performance.

Technical notes

Notes

The website uses WordPress CMS with the Astra theme and Elementor page builder, indicating a modern and flexible infrastructure. SEO is enhanced by Rank Math PRO plugin and structured data in JSON-LD format, improving search engine visibility. Hosting is provided by team.blue nl B.V., a known registrar and hosting provider, with DNSSEC enabled for DNS security. Performance is moderate with responsive design and mobile optimization evident. Accessibility is basic but could be improved. No analytics or tracking scripts were explicitly detected in the provided content, suggesting minimal user tracking. The technical setup is solid but can benefit from enhanced security headers and privacy compliance features.
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.
