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

Welle Casino is an online gambling platform operated by JER-TEAM N.V., licensed in Curacao, offering a variety of casino games including slots, poker, blackjack, and live dealer experiences. The website targets adult users interested in online casino gaming and positions itself as a premium service with multiple game providers and payment options. Technically, the site is built on a modern Angular framework, integrates Google Analytics and Tag Manager for tracking, and uses CDN services for content delivery. The site is mobile optimized and provides a good user experience with clear navigation and professional design. Security-wise, HTTPS is enforced and no obvious vulnerabilities or exposed sensitive data were found, though security headers are not explicitly detected, suggesting room for improvement. Privacy policies and terms of service are present and comprehensive, but cookie consent mechanisms appear absent, indicating a potential compliance gap. The WHOIS data is privacy protected, which is common for gambling domains, but the domain is consistent with the business claims and licensing information. Overall, the site demonstrates a moderate to good security posture and business credibility, with recommendations to enhance security headers and privacy compliance.

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

10 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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 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

      • 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

Welle Casino operates in the online gambling sector, leveraging a Curacao license to offer a broad portfolio of casino games. The business model focuses on attracting adult gamblers through a premium user experience and partnerships with multiple game providers. The presence of affiliate partnerships, such as with Clash of Slots, indicates an active marketing and growth strategy. The company maintains a consistent brand presence across social media platforms, enhancing customer engagement and trust. The lack of direct contact emails or phone numbers on the site suggests a preference for contact via forms or social channels, typical in this industry. The business appears medium-sized with a focus on digital presence and compliance with licensing requirements.

Security posture

The website enforces HTTPS and avoids exposing sensitive data in its HTML content. It integrates standard analytics tools but lacks explicit security headers like CSP or HSTS, which are recommended to mitigate common web attacks. No visible vulnerable libraries or insecure scripts were detected. The absence of a cookie consent banner may pose GDPR compliance risks. Incident response and security policy information are not publicly available, which could be improved to enhance transparency and readiness. Overall, the security posture is moderate with good foundational practices but room for enhancement in headers and compliance mechanisms.

Recommendations

  1. Implement comprehensive security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  2. Add a cookie consent banner and explicit cookie policy to improve GDPR compliance and user privacy transparency.
  3. Publish clear security and incident response policies accessible to users and stakeholders.
  4. Enhance accessibility features to meet recognized standards and improve user inclusivity.
  5. Consider providing direct contact information such as support emails or phone numbers to improve customer trust and service.

Technical notes

Notes

The site uses Angular 17 as its primary framework, indicating a modern and maintainable front-end architecture. It leverages Google Fonts for typography and Google Tag Manager and Analytics for tracking user behavior. Content is served via CDN domains such as cdn.chipychapa.com, improving load times and availability. The site is responsive and optimized for mobile devices, with good SEO meta tags and structured navigation. However, the lack of detected CMS suggests a custom or proprietary solution. Performance is moderate with some room for optimization. No critical technical debt or outdated libraries were identified, but security header implementation is lacking.
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.
