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.

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

SAZKA operates in the gambling and lottery sector with a business model focused on both offline and online sales of lottery tickets, betting, and casino games. Its competitive advantage lies in its market leadership, brand recognition, and comprehensive product portfolio. Revenue streams include lottery ticket sales, sports betting, and online casino gaming. The target customer segment is adult residents of the Czech Republic interested in legal gambling activities. The company shows growth potential through digital transformation and mobile app offerings. Partnerships with Allwyn AG and other service providers strengthen its ecosystem. Strategic observations include the importance of maintaining regulatory compliance, enhancing security posture, and expanding digital engagement to sustain market leadership.

Security posture

The website exhibits a solid security foundation with HTTPS enabled and use of sandboxed iframes for embedded betting content. Security headers such as Referrer-Policy are present, but explicit Content Security Policy headers and other security headers like X-Frame-Options are not detected, representing an area for enhancement. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of a published security policy or incident response contact limits transparency. Compliance with GDPR is evident through cookie consent and privacy policy disclosures. Overall, the security maturity is good but could benefit from formalized vulnerability disclosure and incident response mechanisms.

Recommendations

  1. Implement and enforce a Content Security Policy (CSP) header to mitigate cross-site scripting risks.
  2. Publish a security policy and incident response contact information to improve transparency and trust.
  3. Add security headers such as X-Frame-Options and X-Content-Type-Options to strengthen defense-in-depth.
  4. Regularly audit third-party scripts and dependencies to prevent vulnerabilities.
  5. Enhance user privacy controls and data retention disclosures to align with best GDPR practices.

Technical notes

Notes

The website is built on the Kentico CMS platform, leveraging modern JavaScript frameworks and CDNs for content delivery. It integrates analytics tools such as Piano Analytics, Google Tag Manager, and Azure Application Insights for performance and user behavior monitoring. The site is mobile-optimized with responsive design and supports multiple platforms including Android and iOS via dedicated apps. Performance is fast with preconnect and preload optimizations. Technical debt appears low with well-structured HTML and CSS. Opportunities exist to improve security headers and formalize vulnerability disclosure processes. The hosting infrastructure appears robust, utilizing Akamai CDN and Azure services.
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.
