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

711 Online Casino operates as a Dutch online gambling platform offering casino games and sports betting services, targeting adult users in the Netherlands. The website promotes bonuses and emphasizes fairness and entertainment. The business appears to be positioned as a popular and trusted online casino within its market segment. Technically, the site uses modern JavaScript frameworks such as Vue.js, integrates marketing and analytics tools like Google Tag Manager and XtremePush, and employs HTTPS for secure communications. However, there is a lack of visible privacy and cookie policies, and no explicit contact information is provided in the analyzed content. Security posture is moderate with HTTPS enabled but missing security headers and formal security policies. Overall, the site is professional but could improve transparency and compliance aspects.

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 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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 company targets the Dutch online gambling market with a business model based on online casino games and sports betting, leveraging promotional bonuses to attract new players. The platform uses modern web technologies and integrates third-party marketing and analytics services to optimize user engagement and advertising effectiveness. The absence of explicit privacy and cookie policies may pose compliance risks, especially under GDPR. The business credibility is supported by consistent branding and WHOIS data alignment. Growth potential exists in the regulated Dutch market, but enhanced compliance and security transparency would strengthen market trust.

Security posture

The website enforces HTTPS, ensuring encrypted data transmission. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are important for mitigating common web attacks. No incident response or vulnerability disclosure information is provided, limiting transparency in security management. The absence of privacy and cookie policies indicates potential GDPR compliance gaps. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security maturity is moderate but requires improvements in policy disclosure, security headers, and incident response readiness to reduce risk.

Recommendations

  1. Implement and publicly disclose a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against web attacks.
  3. Publish incident response and vulnerability disclosure information with dedicated contact channels such as security@ or abuse@ emails.
  4. Provide clear and accessible contact information including company emails and phone numbers to improve trust and compliance.
  5. Regularly audit third-party scripts and marketing tools to ensure they do not introduce vulnerabilities or privacy risks.

Technical notes

Notes

The website uses a modern tech stack with Vue.js framework, asynchronous loading of Google Tag Manager and other marketing SDKs, and structured data for SEO. Performance is moderate with good mobile optimization and basic accessibility features. The site lacks some advanced SEO and accessibility optimizations but maintains a professional design and user experience. Hosting provider details are not explicit. The site could benefit from enhanced security configurations and improved compliance documentation to reduce technical and regulatory risks.
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.
