Risk levelLow

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

LeoVegas Nederland is a prominent online gambling and sports betting platform targeting the Dutch market. The website offers a comprehensive range of casino games, live dealer experiences, and sports betting options, positioning itself as a leading operator in the Netherlands. The platform is designed with modern web technologies including React and Next.js, ensuring good mobile optimization and user experience. While the site is professionally designed and well-branded, it lacks visible privacy and cookie policies in the provided content, which is a compliance gap. Security posture is generally strong with HTTPS enforced and no visible vulnerabilities, but the absence of security headers is a noted area for improvement. WHOIS data confirms the legitimacy and consistency of the domain registration, aligning with the business claims. Overall, the site is a trustworthy and professional gambling operator with room to enhance privacy transparency and security best practices.

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

2 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. 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

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

LeoVegas Nederland operates under the parent company LeoVegas Gaming plc, serving the Dutch market with licensed online gambling services. Its business model revolves around providing casino games, live casino, and sports betting, targeting adult users (18+). The company maintains a strong market position with localized content and multiple sister sites in other European countries. The platform leverages a modern tech stack and focuses on mobile-first gaming experiences. Revenue streams likely include betting margins, game provider partnerships, and affiliate marketing. The absence of explicit contact information and privacy policies in the visible content suggests potential areas for customer trust enhancement. The company’s ecosystem includes multiple regional domains, indicating a broad European presence.

Security posture

The website enforces HTTPS with an excellent SSL configuration, ensuring secure data transmission. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected in the provided data, which could expose the site to certain web-based attacks. No exposed sensitive data or vulnerable libraries were identified. Forms and inputs appear secure but lack explicit CSRF tokens or visible security measures in the HTML snippet. Incident response and security policy information are not publicly visible, indicating a potential gap in transparency. Overall, the security posture is solid but could be improved by implementing and advertising comprehensive security headers and policies.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies to enhance GDPR compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add visible incident response and security contact information to improve transparency and readiness.
  4. Ensure all forms include CSRF protection and input validation to prevent injection attacks.
  5. Regularly audit third-party scripts and libraries to avoid vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website uses a modern React-based framework (Next.js) combined with Emotion CSS and Material-UI for styling and UI components. This tech stack supports server-side rendering and good performance. The site is mobile optimized and uses responsive design principles. The presence of multiple deferred JavaScript chunks indicates modular loading, which can improve load times. However, no explicit CMS was detected, suggesting a custom or proprietary content management solution. Performance is moderate, with room for optimization in script loading and caching. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be enhanced with ARIA roles and better keyboard navigation support.
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.
