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

CasinoHrac.cz is a Czech-language online portal dedicated to online casino enthusiasts, providing reviews, bonus information, and payment method guides. The business operates primarily as an affiliate marketing platform, linking users to various online casinos with VIP bonuses. The company behind the site is identified as Sazeni-On-line, founded in 2020 and based in Prague, Czech Republic. The site targets adult gambling players within the Czech market and offers educational content to enhance user knowledge about online gambling. Technically, the website employs modern web technologies including JavaScript frameworks, Google Tag Manager for analytics, and responsive design to ensure usability across devices. Security posture is adequate with HTTPS enforced and affiliate links properly marked, but lacks visible security headers and explicit privacy or cookie policies. The absence of WHOIS data limits domain legitimacy verification, though the site content and structured data suggest a legitimate operation. Overall, CasinoHrac.cz presents a professional and content-rich platform for its niche audience but should improve privacy compliance and security transparency.

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

12 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 holds a niche position in the Czech online gambling affiliate market, leveraging detailed casino reviews and bonus offers to attract users. Its business model relies on affiliate commissions from casino partners, supported by a network of related domains such as Sazeni-On-line and BetterGambling.eu. The site demonstrates a consistent brand presence and active social media engagement, which supports user acquisition and retention. Growth potential exists through expanded educational content and enhanced user trust via improved compliance and transparency. The lack of direct contact information and privacy policies may hinder credibility with more cautious users. The company appears small but focused, with a clear target audience and specialized content offerings.

Security posture

CasinoHrac.cz maintains a basic to moderate security posture. The site uses HTTPS, ensuring encrypted communications, and marks affiliate links with appropriate rel attributes to mitigate SEO penalties. However, no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which could expose the site to certain web-based attacks. There is no visible privacy policy or cookie consent mechanism, which is a compliance gap under GDPR. No incident response or security contact information is provided, limiting transparency in case of security issues. The site does not expose sensitive data or show signs of vulnerable libraries in the analyzed content. Overall, the security posture is functional but could be significantly improved by implementing standard security headers, privacy compliance measures, and incident response readiness.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish explicit contact information for general and security-related inquiries.
  4. Conduct regular audits of third-party scripts and dependencies to identify and mitigate vulnerabilities.
  5. Establish an incident response plan and publish relevant contact channels for security incidents.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with custom state management ($store), Swiper.js for interactive sliders, and Google Tag Manager for analytics and event tracking. The site is mobile responsive with adaptive images and fonts loaded via WOFF2. SEO is supported by canonical links, hreflang tags for alternate languages, and structured data in JSON-LD format describing the organization and website. No CMS was identified, suggesting a custom or static site generator approach. Performance appears moderate with asynchronous loading of scripts and optimized assets. Accessibility is basic, with some ARIA or semantic enhancements likely needed. Hosting provider and backend infrastructure details are not discernible from the provided data.
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.
