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

Guia Bet BR is a Brazilian Portuguese website focused on ranking and promoting online betting and casino platforms targeted at Brazilian users. The site offers a curated list of gambling platforms with bonuses, fast withdrawals via PIX, and user comments to enhance trust. The business model is affiliate marketing, driving traffic to various gambling sites. Technically, the site uses modern web standards, including HTML5, CSS3, JavaScript, and Google Fonts, with a responsive design and interactive features like carousels and toast notifications. However, no CMS or hosting provider information is evident. Security posture is moderate; HTTPS is used, but no security headers or privacy policies are present, and no contact or incident response information is provided. The WHOIS data is missing, raising concerns about domain legitimacy. Overall, the site is functional and visually consistent but lacks critical compliance and security transparency, posing risks to users and partners.

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

The website operates in the online gambling affiliate sector, targeting Brazilian bettors interested in sports betting and online casinos. It leverages a broad network of gambling domains, many with unusual TLDs, suggesting a strategy to capture diverse market segments or evade regulatory scrutiny. The lack of official company information, privacy policies, and contact details reduces business credibility. The site appears small in scale but focused on content quality and user engagement through comments and badges. Revenue likely derives from affiliate commissions. The absence of clear partnerships or certifications limits trust. Growth potential depends on regulatory compliance and improved transparency.

Security posture

Security maturity is low to moderate. The site uses HTTPS but lacks visible security headers such as Content-Security-Policy, X-Frame-Options, or HSTS. No forms collect sensitive data, reducing attack surface, but absence of privacy and cookie policies indicates compliance gaps, especially regarding GDPR or Brazilian LGPD. No incident response or security contact information is provided. The WHOIS data absence is a red flag for domain legitimacy and potential abuse. No analytics or tracking scripts were detected, which may reduce privacy risks but also limits marketing insights. Overall, the site should improve transparency, implement security headers, and provide clear policies to enhance trust and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies to comply with GDPR and LGPD.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to harden site security.
  3. Provide clear contact information including security incident response channels.
  4. Verify and update domain registration to ensure WHOIS data availability and legitimacy.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance.

Technical notes

Notes

The website is built with standard web technologies and custom JavaScript for UI features like carousels and copy-to-clipboard functionality. It uses Google Fonts for typography and has a responsive design optimized for mobile devices. The site does not appear to use a CMS or third-party analytics/tracking tools, which simplifies the tech stack but limits marketing data. Performance is moderate with no obvious heavy resources. The absence of security headers and privacy policies indicates technical debt in compliance and security best practices. The site could benefit from improved accessibility and SEO enhancements. Hosting provider and infrastructure details are not disclosed, limiting deeper technical assessment.
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.
