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

The website zahulimeuvidime.cz operates as a Czech-language online casino informational and affiliate platform, providing detailed reviews, bonus offers, and guides related to new Czech online casinos in 2025. It targets adult Czech players interested in gambling, offering a curated selection of casino brands and payment methods. The business model focuses on affiliate marketing and content provision within the gambling sector. Technically, the site is built on WordPress, leveraging modern JavaScript libraries such as jQuery, Swiper, and Tippy.js, and is hosted behind Cloudflare, ensuring reasonable performance and mobile optimization. Security posture is moderate with HTTPS enforced, but lacks explicit security headers and published security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism or terms of service. WHOIS data raises concerns due to a future domain creation date, which impacts trustworthiness. Overall, the site is functional and content-rich but would benefit from enhanced transparency and security practices.

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

  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 platform positions itself as a niche informational service within the Czech online gambling market, focusing on new casinos launching in 2025. It leverages detailed content, structured data, and affiliate links to attract and convert users. The site emphasizes trust signals such as licensing checks and user reviews but lacks direct company contact details, which may limit credibility. The business targets adult Czech players seeking updated casino options and bonuses. Growth potential depends on maintaining up-to-date content and expanding trust indicators. The partnership ecosystem includes various casino brands promoted via affiliate links. Strategic observations suggest improving compliance and transparency to strengthen market position.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No incident response or security policy information is published, limiting transparency. The site does not display cookie consent mechanisms, which is a GDPR compliance gap. No known vulnerabilities or outdated libraries were detected in the provided content. The suspicious WHOIS data introduces a reputational risk. Overall, the security posture is adequate for an informational site but requires improvements to meet best practices and regulatory expectations.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  2. Add a cookie policy and explicit consent mechanism to comply with GDPR and improve user trust.
  3. Publish clear terms of service and security policy pages detailing data protection and incident response procedures.
  4. Provide verifiable contact information including company emails and phone numbers to increase business credibility.
  5. Investigate and correct WHOIS data inconsistencies to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website uses WordPress CMS with a modern front-end stack including jQuery, Swiper for sliders, Tippy.js for tooltips, and validation libraries. It loads fonts and styles efficiently with preload hints and minified CSS/JS. Hosting behind Cloudflare provides DNS and CDN benefits. Performance is moderate with good mobile optimization and responsive design. Accessibility is basic but could be improved with ARIA roles and better semantic markup. SEO is supported by meta tags, canonical links, and structured JSON-LD data for organization, news article, and FAQ. No analytics or tracking scripts were detected, indicating minimal user tracking. Technical risks include missing security headers and incomplete privacy compliance. Overall, the infrastructure is solid but can be enhanced for security and compliance.
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.
