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

CasinoArena.cz is a Czech-language online media portal specializing in providing comprehensive information, reviews, and guides related to online casinos, slot machines, and gambling bonuses targeted at Czech players. Operated by GTO Solutions s.r.o., the site positions itself as a trusted source for responsible gambling information and affiliate marketing for licensed Czech online casinos. The website features a well-structured content layout with clear navigation and regularly updated articles, catering primarily to adult Czech-speaking audiences interested in online gambling. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager, and Cookiebot for consent management, ensuring compliance with GDPR and cookie regulations. The site is served over HTTPS with good SSL configuration, though some security headers are not explicitly detected. Performance and mobile optimization are adequate, providing a good user experience across devices. From a security perspective, the site demonstrates good practices such as secure form handling with consent checkboxes and no visible sensitive data exposure. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in security maturity. The lack of WHOIS data for the domain is a notable concern, reducing domain trustworthiness despite the professional appearance and content quality of the site. Overall, CasinoArena.cz presents a credible and professional online gambling information portal with solid technical implementation and privacy compliance. Strategic improvements in domain registration transparency, security header implementation, and incident response readiness would enhance its security posture and trustworthiness further.

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

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

CasinoArena.cz operates in the online gambling media sector within the Czech Republic, targeting adult players interested in licensed online casinos and slot games. The business model revolves around content publishing and affiliate marketing, generating revenue through partnerships with Czech online casinos. The site maintains a strong partnership ecosystem including regulatory bodies and responsible gambling initiatives, enhancing its credibility. While the company is relatively small, it holds a stable market position as a go-to resource for Czech casino players. Growth potential exists through expanded content offerings and deeper integration with casino operators. The absence of direct contact phone numbers and physical addresses suggests a primarily digital presence focused on content delivery rather than direct customer service.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforced and use of consent management tools like Cookiebot. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web-based attacks. The use of GET method for form submission collecting emails is suboptimal from a security standpoint. No incident response or vulnerability disclosure information is provided, indicating limited preparedness for security incidents. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security maturity is adequate for a content site but could be improved with enhanced headers, secure form methods, and published security policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Change form submission methods from GET to POST for collecting personal data to enhance data security.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Verify and update WHOIS domain registration information to improve domain trust and legitimacy.

Technical notes

Notes

The website uses a standard modern web stack with HTML5, CSS3, and JavaScript, including jQuery and Google Tag Manager for analytics and marketing. Cookiebot is integrated for GDPR-compliant cookie consent management. The site is mobile responsive with good navigation and SEO optimization. Performance is moderate, with asynchronous loading of scripts to improve page load times. No CMS was explicitly detected, suggesting a custom or lightweight platform. Hosting provider details are not available from the data. The site uses canonical URLs and structured data (JSON-LD) for SEO and rich snippet support. Some technical debt is noted in the use of GET for form data and missing security headers, which should be addressed to modernize the security posture.
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.
