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

EstrelaBet is an online sports betting platform targeting adult users primarily in Brazil. The website is currently geo-restricted and blocked in certain countries, as indicated by the displayed message and Cloudflare WAF protection. The business model focuses on sports gambling services, but the site lacks publicly accessible privacy, cookie, or terms of service policies, and no contact information is provided on the landing page. Technically, the site uses Cloudflare for DNS and security, with basic HTML, CSS, and JavaScript technologies. Performance and mobile optimization are moderate to basic, with minimal SEO and accessibility features. Security posture is limited with no visible security headers or advanced protections beyond Cloudflare's WAF. Overall, the site presents a low trust profile due to minimal content and lack of compliance documentation.

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

8 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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  3. 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"

    • 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';…

  4. 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

The company operates in the online gambling sector, a highly regulated and competitive market. The domain registration is consistent with the brand and active until 2025, suggesting a legitimate business presence. However, the absence of detailed business information, contact details, and compliance policies limits transparency and trust. The platform likely targets Brazilian users but restricts access in other countries, possibly due to legal constraints. No partnerships or subsidiaries are publicly linked. The business model relies on sports betting revenue streams, but growth and market positioning cannot be fully assessed from the available data.

Security posture

The website benefits from Cloudflare's security infrastructure, including WAF and DNS services, which provide baseline protection against common attacks and DDoS. However, the lack of visible security headers, absence of privacy and cookie policies, and no incident response or vulnerability disclosure information indicate immature security governance. The geo-restriction message suggests compliance with regional legal requirements but also limits user access and transparency. No exposed vulnerabilities or sensitive data leaks were detected in the analyzed content. Overall, the security posture is basic and requires enhancements to meet industry best practices and regulatory compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add clear contact information including support and security incident response channels.
  3. Enhance security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Improve SEO, accessibility, and mobile responsiveness to enhance user experience and reach.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

  3. No contact information or forms present.

Technical notes

Notes

The website uses a simple tech stack with HTML5, CSS3, and JavaScript, hosted behind Cloudflare which provides DNS and WAF services. The site loads a logo image from a CDN subdomain and includes Cloudflare Insights for analytics. Performance is moderate with basic mobile optimization and accessibility. No CMS or advanced frameworks were detected. The site lacks meta tags beyond the title and charset, limiting SEO effectiveness. The presence of Cloudflare challenge scripts and an iframe indicates geo-restriction and WAF blocking, which impacts content accessibility and analysis. Technical debt appears low but modernization opportunities exist in SEO, accessibility, and security headers.
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.
