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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Security headers

    • High

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 as an important media entity within the Czech sports betting ecosystem, leveraging affiliate marketing and advertising revenue streams. It maintains partnerships with multiple related sports news portals under the GTO Solutions umbrella, enhancing its market reach. The business model focuses on providing valuable betting-related content and tools to Czech bettors, supported by regulatory compliance and responsible gaming initiatives. The company benefits from trust signals such as membership in the Institute for Regulation of Gambling and cooperation with responsible gaming projects. Growth potential is supported by extensive content coverage and a loyal user base.

Security posture

BetArena.cz exhibits a good security maturity level with enforced HTTPS and no visible sensitive data leaks. The site uses Google Tag Manager and Analytics with consent management, indicating awareness of privacy regulations. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or security policy information is publicly available, which could be enhanced to improve transparency and readiness. No vulnerabilities or malware indicators were detected in the HTML content. Overall, the security posture is adequate for a media and affiliate website but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and user trust.
  3. Regularly audit third-party scripts and dependencies to prevent vulnerabilities from external sources.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Consider establishing a formal vulnerability disclosure program to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website uses a standard modern web stack with JavaScript, jQuery, and Google Tag Manager for analytics and marketing. The HTML is well-structured with proper meta tags for SEO and mobile responsiveness. Performance is moderate with deferred script loading and preconnect hints for external domains. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The site includes multiple affiliate and advertising banners, integrated with Google DoubleClick. Technical debt appears low, but security header implementation is incomplete. Overall, the technical infrastructure supports a stable and user-friendly experience with opportunities for security and accessibility enhancements.
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.
