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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

Ceskaonlinekasina.cz operates in a niche market segment serving Czech online casino players. Its business model is primarily affiliate marketing, linking users to licensed Czech casinos and earning commissions. The site leverages partnerships with affiliate networks such as Affilmaster. Its competitive advantage lies in localized content, Czech language support, and focus on legal Czech casinos, differentiating it from international gambling sites. The platform targets adult Czech residents interested in regulated gambling, offering comprehensive information on bonuses, payment methods, and legal compliance. Growth potential exists as the Czech online gambling market expands, with new casinos launching in 2024. The site maintains trust signals such as links to official Czech regulatory bodies and a Trustpilot widget, enhancing credibility. However, the absence of direct contact information and limited privacy disclosures may impact user trust.

Security posture

The website demonstrates a moderate security posture. HTTPS is enforced, and Google site verification meta tags are present, indicating ownership verification. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No visible forms or input fields reduce attack surface but also limit user interaction. There is no published security policy or incident response contact information, which is a gap in transparency and readiness. Privacy compliance is basic, lacking explicit cookie consent mechanisms or GDPR statements. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the site is secure enough for informational purposes but should enhance security headers and privacy practices to improve trust and compliance.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web attacks.
  2. Publish a detailed privacy policy with explicit GDPR compliance statements and introduce a cookie consent mechanism to meet legal requirements.
  3. Add clear contact information including business email and security incident response contacts to improve transparency and user trust.
  4. Regularly audit and update third-party scripts and affiliate links to ensure no vulnerabilities or privacy risks are introduced.
  5. Enhance accessibility features and provide more detailed terms of service to improve user experience and legal clarity.

Technical notes

Notes

The website uses a clean and modern technical stack with HTML5, CSS3, and JavaScript, leveraging Google Fonts for typography. Hosting is via Cloudflare DNS, likely providing CDN and DDoS protection benefits. The site is mobile responsive with a grid layout and adaptive design for smaller screens. SEO is supported by meta description, canonical tags, and hreflang attributes. Performance appears moderate with no heavy scripts detected. However, no CMS or advanced frameworks are identified, suggesting a custom or static site. The site lacks advanced accessibility features and security headers, which are areas for technical improvement. Overall, the infrastructure is solid for a small affiliate site but could benefit from modernization and enhanced security configurations.
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.
