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

4 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 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';…

  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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Klimaatplein occupies a niche position as an information and advisory platform in the Dutch energy sustainability market. Its competitive advantage lies in offering a comprehensive suite of tools, practical advice, and a partner network that supports businesses in their climate-conscious transformation. The business model revolves around content provision and partnerships rather than direct product sales. The presence of a broad partner ecosystem and active content updates indicate growth and engagement within its target market. The platform's focus on SMEs and medium-sized enterprises aligns with the domain age and content maturity, supporting sustainable business growth and market relevance.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and DNSSEC enabled, reducing risks of man-in-the-middle attacks and DNS spoofing. The use of a cookie consent plugin with opt-in mechanisms aligns with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of security headers such as Content-Security-Policy and a published security policy or incident response plan suggests room for improvement in defense-in-depth and transparency. The lack of a security.txt file limits vulnerability disclosure facilitation. Overall, the security posture is solid but could be enhanced by adopting additional best practices and formal policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Publish a dedicated security policy and incident response information to improve transparency and preparedness.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.
  5. Enhance data retention and privacy policy details to explicitly state analytics data handling and retention periods.

Technical notes

Notes

The website is built on WordPress CMS with modern plugins such as Yoast SEO for search optimization and Complianz for GDPR cookie management. It uses Google Tag Manager and Google Analytics for tracking and marketing purposes. The site loads Typekit fonts and uses SVG icons for UI elements, indicating attention to design and performance. Mobile optimization is excellent with responsive navigation and images. Performance is moderate, likely due to rich media content and multiple external resources. The site benefits from DNSSEC and HTTPS, ensuring secure communications. Technical debt appears low, but the absence of some security headers and explicit hosting provider information suggests potential areas for infrastructure transparency and hardening.
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.
