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

5 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 operates in the real estate sector, targeting homeowners, buyers, and business clients in the Netherlands. Their business model revolves around brokerage services, including sales, purchases, valuations, and mortgage advice. The website indicates a medium-sized enterprise with a well-established market position since 2012. The presence of customer testimonials, high ratings, and partnerships with recognized platforms like Funda and NVM enhance their competitive advantage. Marketing efforts include SEO optimization, social media engagement, and customer interaction via forms and chat widgets. The company appears focused on regional growth and maintaining strong client relationships.

Security posture

The website employs HTTPS with a valid SSL certificate, uses Google reCAPTCHA to protect forms, and includes honeypot fields to reduce spam. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, which could improve protection against common web attacks. No exposed sensitive data or vulnerable libraries were found in the HTML content. The absence of a published security policy or incident response contact limits transparency. Overall, the security posture is good but could be enhanced by implementing recommended headers and publishing security-related policies.

Recommendations

  1. Publish a comprehensive privacy policy to improve GDPR compliance and user trust.
  2. Implement and verify security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a visible security policy and incident response contact information to enhance transparency.
  4. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  5. Continue optimizing website performance and accessibility to maintain high user experience.

Technical notes

It integrates Google Analytics, Google Tag Manager, and Facebook Pixel for analytics and marketing. The site uses jQuery 3.5.1 and includes a Sitekick widget for customer engagement.

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.
