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

Green Leisure Group Coöperatie U.A. is a specialized sustainability consulting cooperative focused on practical and strategic sustainability solutions for the tourism, hospitality, cultural, event, and sports sectors primarily in the Netherlands. The company offers expert advice, project management, and sector-specific sustainability programs such as Green Stages, Green Sport, and Green Leisure. Their market position is that of a trusted advisor with a cooperative business model, serving a niche audience of organizations seeking to improve their sustainability practices. Technically, the website is built with modern web standards including HTML5, CSS3, and jQuery, with good mobile optimization and a professional design. The site uses HTTPS with strong SSL configuration but lacks some security headers and cookie consent mechanisms. No major vulnerabilities or exposed sensitive data were detected, and the site does not appear to use extensive tracking or analytics, indicating a privacy-conscious approach. From a security perspective, the site demonstrates a solid baseline with HTTPS and no visible vulnerabilities, but it could improve by implementing security headers, publishing a security policy, and adding incident response contact information. The absence of a cookie consent mechanism is a minor compliance gap under GDPR. Overall, the website is professional, trustworthy, and well-aligned with the business's sustainability mission. The domain registration data is consistent and legitimate, supporting the company's credibility. Strategic recommendations include enhancing security headers, adding cookie consent, and publishing security and incident response policies to further strengthen trust and compliance.

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

6 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

    • 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

  2. Security headers

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

Green Leisure Group operates as a cooperative providing sustainability consulting services to tourism, hospitality, cultural, and sports sectors. Their competitive advantage lies in their specialized knowledge and network approach, enabling them to deliver both individual and collective sustainability projects. The business model focuses on advisory and project facilitation, with revenue likely derived from consulting fees and project partnerships. Their target customers include businesses and organizations within the Dutch tourism and cultural sectors, as well as municipalities. The company demonstrates growth through partnerships with public entities and involvement in multiple sustainability initiatives. Their ecosystem includes collaborations with Trees for All and various regional programs, enhancing their market presence and impact.

Security posture

The website maintains a good security posture with HTTPS enforced and no visible sensitive data exposure. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure information is provided, which could limit responsiveness to security events. The absence of a cookie consent mechanism is a compliance gap under GDPR. Overall, the security maturity is moderate to good, with room to enhance policies and technical controls to align with best practices and regulatory requirements.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner or mechanism to comply with EU cookie regulations.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Consider creating a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website uses a clean and modern technical stack with HTML5, CSS3, and jQuery. It loads web fonts efficiently and is mobile optimized with responsive design. Performance is moderate, with no major issues detected. The site does not appear to use a common CMS, suggesting a custom or static site approach. No analytics or tracking scripts were detected, indicating a privacy-focused implementation. Technical debt appears low, but the absence of security headers and cookie consent mechanisms are notable gaps. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports the business goals but could benefit from security and compliance enhancements.
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.
