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. 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. 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 256-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

Groen Centraal holds a strong market position as a regional hospitality provider specializing in conference and meeting venues. Its collaborative business model leverages multiple partner locations to offer diverse options to clients. The target audience includes corporate clients and organizations requiring event spaces. The website reflects a medium-sized enterprise with a founding date consistent with domain registration. The partnership ecosystem is well represented by linked partner domains, indicating a cohesive network. Revenue streams likely derive from venue rentals and event services. Growth potential is supported by professional branding and digital presence, though direct contact details could be enhanced to improve client engagement.

Security posture

The website demonstrates a baseline security maturity with HTTPS enforced and cookie consent mechanisms in place, supporting GDPR compliance. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No published security policy or vulnerability disclosure process limits transparency and incident readiness. The use of third-party scripts like Google Tag Manager and Hotjar introduces potential risk vectors that require ongoing monitoring. Overall, the security posture is adequate for the business type but would benefit from formalized policies, enhanced headers, and explicit incident response contacts to mitigate risks and improve trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear security policy and vulnerability disclosure page to improve transparency and incident response readiness.
  3. Add explicit security incident contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and plugins to minimize vulnerabilities.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform utilizing Bootstrap for responsive design and jQuery for interactivity. It employs modern web technologies including Font Awesome icons and Nivo Lightbox for media display. Performance is moderate with caching and minification evident. SEO is enhanced through Yoast SEO plugin and structured data (JSON-LD) implementation. Cookie consent is managed via Cookiebot, integrating with Google Tag Manager for analytics and tracking. The site is mobile-optimized and features a clean navigation structure. Technical risks include reliance on multiple third-party scripts and lack of some security headers. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure is solid with room for security and accessibility improvements.
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.
