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

The website www.glutenvrij.nl is operated by the Nederlandse Coeliakie Vereniging, a Dutch non-profit organization dedicated to supporting individuals affected by coeliac disease and gluten intolerance. The site offers comprehensive medical information, recipes, dietary advice, community activities, and membership benefits, positioning itself as a leading resource in the Netherlands for gluten-free living. The target audience includes patients, families, and caregivers seeking trustworthy information and support. Technically, the website is built on the Procurios CMS platform, utilizing JavaScript and CSS with frameworks such as Prototype.js. The site demonstrates good mobile optimization, accessibility, and SEO practices, although hosting details are not explicitly identified. Performance is moderate, with no critical technical issues detected. From a security perspective, the site enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements. However, it lacks visible security policies, incident response contacts, and advanced security headers, which are recommended for enhanced protection. No vulnerabilities or exposed sensitive data were found during analysis. Overall, the website is professional, trustworthy, and compliant with privacy regulations, serving its community effectively. Strategic improvements in security transparency and incident response readiness would further strengthen its posture.

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

1 finding rated critical or high. Fix these first.

  1. 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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

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 Nederlandse Coeliakie Vereniging operates as a non-profit entity focused on healthcare and community support for coeliac disease in the Netherlands. Its business model centers on membership services, educational content, and community engagement. The organization maintains a strong market position as a trusted authority in gluten-free living, supported by partnerships with related domains such as ncv.nl and coeliactive.nl. Revenue streams likely include membership fees and sales via the NCV webwinkel. The website's content and services cater to a broad demographic, including children, youth, and adults affected by gluten intolerance. The partnership ecosystem and active social media presence indicate a well-established operational framework.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and a comprehensive cookie consent mechanism ensuring GDPR compliance. While no critical vulnerabilities or exposed sensitive data were detected, the absence of a published security policy, incident response contacts, and security.txt file represents a gap in transparency and preparedness. The site would benefit from implementing additional security headers such as Content-Security-Policy and X-Frame-Options to mitigate common web threats. Overall, the security maturity is good but can be enhanced by formalizing policies and improving communication channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting and handling of security issues.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  5. Regularly review and update cookie and privacy policies to maintain compliance with evolving regulations.

Technical notes

Notes

The website is built on the Procurios CMS platform, leveraging JavaScript and CSS with Prototype.js framework. The HTML structure is valid and includes responsive design elements for mobile optimization. Performance is moderate, with asynchronous loading of scripts to improve user experience. SEO is supported by proper meta tags and structured navigation. Accessibility features such as skip links and labeled form elements are present, enhancing usability. No outdated or vulnerable libraries were detected. Hosting provider details are not disclosed, which could be considered for future transparency. Overall, the technical infrastructure is solid with room for performance optimization.
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.
