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

Markant Outdoorcentrum is a specialized hospitality business located in the Achterhoek region of the Netherlands, offering group outdoor activities, corporate events, school camps, accommodation, and catering services. The website is professionally designed with a clear focus on multiple target audiences including colleagues, friends & family, and school groups. The business positions itself as a regional leader in outdoor event hosting with a comprehensive service offering. Technically, the website is built on WordPress with modern libraries such as React-datepicker and Swiper.js, and employs performance and SEO plugins like WP Rocket and The SEO Framework. The site is mobile-optimized and accessible, with good SEO practices implemented. Security posture is solid with HTTPS enforced and cookie consent managed via Cookiebot, but lacks explicit security headers and published security policies. No direct contact information or privacy policy pages were found, which slightly impacts privacy compliance and user trust. WHOIS data aligns well with the website content, indicating legitimacy and consistency. Overall, the website is secure, professional, and trustworthy but would benefit from enhanced transparency in privacy and security policies.

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 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 hospitality sector focusing on outdoor group activities and events, targeting corporate clients, families, and educational institutions. Its business model revolves around event hosting combined with accommodation and food services, generating revenue through activity bookings and event packages. The website reflects a mature digital presence with integrated booking systems and marketing tools. The absence of explicit contact details on the site suggests a possible reliance on booking platform communications. The company appears to maintain a strong regional presence with a consistent brand and clear market positioning. No partnerships or subsidiaries were identified from the domain analysis.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and cookie consent mechanisms in place. However, the lack of security headers such as Content-Security-Policy and absence of published security or incident response policies indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses third-party analytics and tracking tools, which require clear privacy disclosures to ensure GDPR compliance. The absence of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. Overall, the security posture is adequate for the business type but could be enhanced by adopting additional best practices and publishing relevant policies.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website footer or main navigation.
  2. Add terms of service page detailing user rights and obligations.
  3. Include explicit contact information such as company email, phone number, and physical address on the website.
  4. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Create and publish a vulnerability disclosure policy or security.txt file to improve security transparency and incident response readiness.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, React-datepicker, and Swiper.js for UI components. Performance optimization is handled by WP Rocket, and SEO is managed via The SEO Framework plugin. The site loads asynchronously scripts for analytics and cookie consent, improving user experience. Mobile optimization is excellent with responsive images and layouts. Accessibility features such as skip links and ARIA labels are present. No major technical debt or deprecated libraries were detected. Hosting provider details were not explicitly found. Overall, the technical infrastructure supports a fast, accessible, and SEO-friendly website suitable for the business needs.
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.
