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. 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';…

  2. GDPR outside view

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

    • 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

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 organization targets stakeholders in the Dutch public and private sectors interested in innovation, education, and cybersecurity. Its business model revolves around event organization, networking facilitation, and recognition through awards. The site demonstrates a mature digital presence with active social media channels and a content-rich blog. The domain age and privacy-protected WHOIS registration align with the organization's profile, indicating legitimacy. The absence of direct contact emails or phone numbers suggests a preference for controlled contact via scheduling tools like Calendly. The organization appears well-positioned in its niche with a focus on collaboration and positive societal impact.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms, indicating a baseline security awareness. However, DNSSEC is not enabled, which could expose the domain to DNS spoofing risks. No explicit security policies or incident response contacts are published, which is a gap in transparency and preparedness. Security headers such as Content-Security-Policy and X-Frame-Options are not detected, which could be improved to mitigate common web attacks. No vulnerable libraries or exposed sensitive data were found. Overall, the security posture is moderate but could benefit from enhanced DNS security and published policies.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Implement additional security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain and regularly update all plugins and libraries to avoid vulnerabilities.

Technical notes

Notes

The website uses a modern WordPress CMS with Elementor page builder and Yoast SEO plugin, indicating a well-supported and extensible platform. It leverages Cloudflare for DNS and possibly CDN services, enhancing performance and security. The site includes Google Tag Manager and reCAPTCHA scripts for analytics and bot protection. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic but could be improved. The site uses multiple CSS and JS libraries for UI and event management. No critical technical debt or deprecated technologies were detected, but enabling DNSSEC and improving security headers would enhance the technical robustness.
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.
