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

    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

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

BetArena.cz holds a solid position in the Czech sports betting information market, leveraging affiliate partnerships with licensed bookmakers to generate revenue. Its business model focuses on content publishing with monetization through affiliate links and advertising. The target audience includes Czech sports bettors and enthusiasts seeking betting tips, live broadcasts, and sports news. The company benefits from a broad partnership ecosystem with related sports and gambling websites, enhancing its reach and content diversity. Growth indicators include regular content updates, extensive coverage of sports events, and integration of responsible gambling messaging. The lack of direct phone contact may limit some customer engagement channels, but the presence of a contact form and email provides basic communication means.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and use of Google Tag Manager and Analytics scripts with consent management. However, it lacks visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No explicit security policy or incident response contact information is provided, which could hinder timely handling of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data reduces trust in domain registration legitimacy, which is a security concern. Overall, the site follows basic security best practices but would benefit from enhanced header configurations and transparency in security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency and readiness for security events.
  3. Verify and publish accurate WHOIS domain registration data to improve domain legitimacy and trustworthiness.
  4. Consider adding direct company phone contact information to improve user trust and support accessibility.
  5. Regularly audit third-party scripts and tracking technologies to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website uses a modern JavaScript-based front end with deferred script loading and asynchronous Google Tag Manager and Analytics integration. It employs responsive design techniques and includes print-specific CSS. The site uses structured data (JSON-LD) to define organization information, aiding SEO. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is moderate with some deferred scripts and external resource loading. Accessibility is basic with room for improvement in ARIA roles and semantic HTML. SEO is good with proper meta tags, canonical links, and structured data. Hosting provider details are not discernible from the HTML content. Overall, the technical infrastructure supports a professional and functional user experience but could be enhanced with improved accessibility and security header implementation.
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.
