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

The website coloringsun.com operates as an online gambling platform branded as ARENA333, offering a variety of gambling games including slots, live casino, sports betting, and more. The site targets adult users, primarily Indonesian speakers, and positions itself as a secure and safe gambling environment using Singapore pro servers. The business appears to be small scale, founded in 2014, with no clear parent company or subsidiaries identified. The site lacks visible privacy, cookie, or terms of service policies, which is a compliance concern. Technically, the site uses Bootstrap for styling, Cloudflare for DNS and hosting, and integrates multiple Facebook Pixels and Google Analytics for tracking and marketing. LiveChat is used for customer support. The site is mobile optimized with basic SEO and accessibility features.

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

7 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 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

    • 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

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

ARENA333 targets the niche online gambling market with a focus on Indonesian users. Its business model revolves around providing access to various gambling games hosted on pro Singapore servers. The site leverages partnerships with multiple game providers and related domains, indicating a networked ecosystem. Revenue likely derives from user betting activity and possibly affiliate marketing. The lack of transparent business and contact information reduces credibility and trust. Growth indicators are unclear due to limited public data. The platform's competitive advantage may lie in its server infrastructure and game variety. Strategic partnerships with related gambling domains suggest an integrated service offering.

Security posture

The website has HTTPS enabled and uses Cloudflare DNS, which provides a baseline of security. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options weakens its defense against common web attacks. No incident response or vulnerability disclosure policies are present, limiting transparency and readiness for security events. The extensive use of tracking pixels raises privacy concerns. No exposed sensitive data or known vulnerabilities were detected in the HTML content. Overall, the security posture is moderate but requires improvements in headers, policies, and compliance to enhance trust and resilience.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement essential security headers (CSP, X-Frame-Options, X-XSS-Protection) to mitigate common web vulnerabilities.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and other privacy regulations.
  4. Add clear contact information including support emails and phone numbers to improve business credibility.
  5. Establish an incident response and vulnerability disclosure policy to enhance security transparency and user trust.

Technical notes

Notes

The website uses a standard Bootstrap framework for responsive design and Cloudflare for DNS and hosting services, indicating a modern infrastructure. Multiple third-party scripts for analytics and marketing are integrated, including Google Tag Manager and Facebook Pixels, which enable extensive user tracking. The site is mobile optimized and has basic SEO metadata. However, the lack of CMS identification and missing security headers suggest technical debt and potential risks. Performance is moderate with no critical errors detected. Opportunities exist to modernize security configurations and improve compliance-related technical implementations.
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.
