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.

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

    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 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

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

TopCasino operates as an affiliate and informational media platform within the regulated Dutch online gambling sector. Its competitive advantage lies in its comprehensive, up-to-date content, including casino reviews, bonus offers, and tools that assist users in selecting suitable casinos. The business model relies on affiliate partnerships with licensed Dutch casinos, leveraging multiple affiliate networks for monetization. The target audience is strictly adults 24+ due to Dutch legal requirements, focusing on responsible gambling. The platform's nomination for Website of the Year 2025 and certifications such as KVA and GPWA reinforce its credibility. The partnership ecosystem includes several affiliate networks and advertising platforms, indicating a mature affiliate marketing operation. Growth indicators include frequent content updates, new game releases, and active promotions. Strategic observations suggest maintaining compliance and enhancing security policies could further strengthen market position.

Security posture

The website demonstrates a moderate to good security posture. HTTPS is enforced site-wide, and CSRF tokens are implemented in forms, indicating attention to common web security practices. Age verification mechanisms are in place to comply with legal requirements. However, the absence of explicit security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security robustness. No public security policy or incident response contact information is provided, which is a gap in transparency and readiness. Third-party scripts from advertising and analytics providers introduce potential risk vectors that require ongoing monitoring. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate but could be improved by implementing additional HTTP security headers and publishing a security policy.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and trust.
  3. Regularly audit and monitor third-party scripts and affiliate links to mitigate risks from external dependencies.
  4. Enhance accessibility features to improve compliance with accessibility standards and broaden user inclusivity.
  5. Maintain up-to-date privacy and cookie consent mechanisms aligned with evolving GDPR requirements.

Technical notes

Notes

The website is built on a modern technology stack featuring JavaScript libraries such as jQuery, Swiper.js for sliders, and Typeahead.js for search autocomplete. Google Tag Manager and Taboola are used for analytics and advertising, indicating a mature digital marketing infrastructure. The presence of CSRF tokens and structured JSON-LD data suggests a well-developed backend, likely using the Yii PHP framework. The site is mobile responsive with good SEO optimization, including meta tags and Open Graph data. Performance is moderate, with some potential for optimization in loading times due to multiple external scripts. No CMS was explicitly detected, implying a custom or framework-based solution. Technical risks include reliance on multiple third-party scripts which require monitoring for vulnerabilities. Overall, the technical infrastructure supports a professional and scalable online presence.
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.
