Gokken onder Controle is a Dutch online platform providing anonymous and free support for individuals struggling with gambling addiction. The service offers online treatment programs, expert advice, and self-assessment tools to help users change their gambling behavior. The website targets individuals in the Netherlands and operates under the legal entity Intermax Group B.V., established in 2007. The platform positions itself as a specialized healthcare support service with a focus on accessibility and anonymity. Technically, the website is built on the Liferay CMS platform, utilizing modern web technologies such as React, jQuery, and YUI. It integrates Google Tag Manager for analytics and tracking, and employs HTTPS for secure communications. The site is moderately optimized for performance and mobile responsiveness, with basic accessibility features and good SEO practices. From a security perspective, the site uses HTTPS but lacks explicit security headers and published security policies or incident response information. No vulnerability disclosure or security.txt files were found. The WHOIS data is consistent with the business claims, showing a mature domain registered to a Dutch company. Cookie consent mechanisms are in place, supporting GDPR compliance. Overall, the website demonstrates a good balance of content quality, technical implementation, and business credibility, with room for improvement in security posture and transparency. The risk level is moderate, with recommendations to enhance security headers, publish security policies, and consider vulnerability disclosure mechanisms.

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 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 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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: 0

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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 platform operates in the healthcare and non-profit sectors, focusing on gambling addiction treatment in the Netherlands. Its business model centers on providing free, anonymous online treatment and expert advice, targeting individuals seeking help for gambling problems. The company benefits from a mature domain and consistent branding, positioning itself as a trusted resource in its niche. The absence of direct contact emails or phone numbers suggests a focus on privacy and anonymity. The use of Liferay CMS and integration with Google Tag Manager indicates a moderate level of digital maturity. No evident partnerships or subsidiaries were identified from the data.

Security posture

The website employs HTTPS, ensuring encrypted communications. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No explicit security or incident response policies are published, and no contact channels for security incidents were found. The absence of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate but could be significantly improved by implementing recommended headers, publishing security policies, and establishing clear incident response channels.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security.
  2. Implement and configure security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a comprehensive security policy and incident response plan on the website.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging React and jQuery libraries, with YUI components also present. Google Tag Manager is used for analytics and tracking, indicating integration with marketing tools. The site uses asynchronous script loading and combines resources for performance optimization. Mobile optimization is good, with responsive design elements and adaptive images. SEO is supported by proper meta tags and Open Graph data. The site does not appear to use a CDN for dynamic resources. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is modern and functional, with moderate performance and room for further 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.
