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

Comeon Casino operates as a prominent online gambling platform in the Netherlands, offering a wide range of casino games including slots, table games, and live casino experiences. The website positions itself as a secure, fast, and exciting destination for online gambling enthusiasts. The target audience is adults interested in regulated online gambling within the Dutch market. The business model revolves around providing digital gambling services with a focus on user engagement and retention through a broad game portfolio. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager for analytics and marketing, and Visual Website Optimizer for A/B testing and optimization. The site is mobile-optimized and performs moderately well, with good SEO practices evident from meta tags and structured data. However, explicit CMS or hosting provider details are not discernible from the provided data. From a security perspective, the site enforces HTTPS and uses consent mechanisms for cookies, indicating a baseline security posture. However, it lacks explicit security headers such as Content-Security-Policy and does not publicly disclose security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is partial, with no visible privacy or cookie policies, which is a gap given the GDPR requirements in the Netherlands. Overall, the website is professionally designed and credible within its industry, but improvements in privacy transparency and security policy publication are recommended to enhance trust and compliance. The domain registration data aligns well with the business claims, supporting legitimacy. Strategic recommendations include publishing comprehensive privacy and cookie policies, implementing security headers, and establishing a vulnerability disclosure program.

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. 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 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

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

Comeon Casino is positioned as a leading online gambling operator in the Dutch market, targeting adult players with a diverse offering of casino games. The company leverages digital marketing and optimization tools to enhance user experience and conversion rates. The business model is based on online gaming revenue streams, likely including deposits, bets, and possibly affiliate partnerships. The absence of explicit parent or subsidiary information suggests it operates as a standalone brand or under a larger gambling group not disclosed in the provided data. The company demonstrates consistent branding and a clear market focus, with trust signals such as licensing implied by the professional presentation. Growth indicators include active use of A/B testing and analytics to optimize the platform.

Security posture

The security posture of the website is solid in terms of transport security with HTTPS enforced. The use of cookie consent mechanisms indicates awareness of privacy regulations. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security robustness. No incident response or security contact information is published, which is a gap for transparency and rapid response. No vulnerabilities or exposed sensitive data were identified in the content or scripts. Compliance with GDPR is partial due to missing privacy and cookie policies. The site uses reputable third-party analytics and optimization tools, which should be monitored for security updates. Overall, the site is secure but could improve in policy transparency and header implementation.

Recommendations

  1. Publish comprehensive and accessible privacy and cookie policies including GDPR compliance details.
  2. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file with clear contact channels.
  4. Provide explicit security and incident response contact information to enhance transparency and trust.
  5. Enhance accessibility features to comply with standards and improve user experience for all users.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with integrations of Google Tag Manager and Visual Website Optimizer for analytics and A/B testing. The site is mobile-optimized and includes structured data (JSON-LD) for SEO. Performance is moderate with asynchronous loading of scripts. No CMS or hosting provider is explicitly identified. The site uses canonical URLs and Open Graph metadata for social sharing. The technical implementation is solid but could benefit from improved accessibility and security header configurations. The use of third-party optimization tools indicates a focus on continuous improvement and data-driven decision making.
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.
