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

Dafabet, operated by Osmila N.V., is a prominent online betting and gambling platform primarily serving the Asian market. Established in 2007 and incorporated in Curaçao, the company offers a broad range of services including sports betting, casino games, live dealer experiences, lottery, and arcade games. The website demonstrates a professional digital presence with strong branding, official sports sponsorships, and comprehensive user engagement features such as multi-language support and mobile optimization. The platform emphasizes security and responsible gaming, including age verification measures and privacy policies aligned with GDPR standards. Technically, the website employs modern JavaScript frameworks, integrates multiple analytics and marketing tools such as Google Analytics, Hotjar, and Matomo, and uses HTTPS with session management features to enhance security. However, the absence of visible security headers and lack of explicit incident response or vulnerability disclosure information indicate areas for improvement in security posture. The WHOIS data for the domain is unavailable, which raises concerns about domain registration transparency and slightly impacts trustworthiness. Overall, Dafabet maintains a solid security and compliance framework suitable for its industry, with good privacy and cookie management practices. The platform's extensive use of third-party advertising and tracking services is balanced by clear user consent mechanisms. Strategic recommendations include enhancing security headers, publishing incident response contacts, and improving WHOIS transparency to bolster trust and compliance further.

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 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

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

Dafabet holds a strong market position as a leading online betting company in Asia, leveraging partnerships with well-known sports teams to enhance brand credibility. Its business model revolves around providing diverse gambling services, targeting adult users interested in sports betting and casino games. Revenue streams likely include betting commissions, casino game margins, and affiliate marketing. The company demonstrates growth through multi-language support and mobile platform availability, catering to a broad demographic. The partnership ecosystem includes affiliate programs and promotional platforms, indicating a mature marketing strategy. Despite the lack of WHOIS transparency, the detailed business information and licensing claims support operational legitimacy.

Security posture

The website exhibits a moderate to good security maturity level, with HTTPS enforced and session timeout mechanisms implemented. Responsible gaming and age verification policies are prominently featured, reflecting compliance with regulatory requirements. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options, and the lack of published incident response or vulnerability disclosure channels, highlight gaps in security best practices. No obvious vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is indicated through privacy policies and cookie consent banners. Overall, the security culture appears adequate but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Publish clear incident response contact information and establish a vulnerability disclosure program or security.txt file to improve transparency and trust.
  3. Enhance accessibility features to meet compliance standards and improve user experience for all users.
  4. Regularly audit and monitor third-party scripts and advertising networks to minimize security risks from external dependencies.
  5. Increase WHOIS data transparency or ensure domain registration details are publicly available to strengthen legitimacy and trust.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of scripts and lazy loading of images to optimize performance. Integration with multiple analytics and marketing platforms indicates a mature digital marketing infrastructure. The site supports multiple languages and device platforms, including mobile, with responsive design elements. However, no specific CMS or hosting provider information was detected. Performance is moderate with room for improvement in accessibility and SEO optimization. The technical stack is robust but could benefit from enhanced security configurations and better documentation of backend infrastructure.
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.
