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

CDH.cz is a Czech Republic-based online media platform specializing in video game cataloging, user reviews, ratings, and gaming news. Established since 2008, it serves as the largest Czech database for video games across multiple platforms including PC, PlayStation, Xbox, Nintendo, and mobile devices. The site targets general gaming audiences in the Czech Republic, offering community features such as forums and user comments. Technically, the site uses a custom CMS with JavaScript libraries like jQuery and Matomo for analytics, and integrates advertising via SSP Seznam. While the site employs HTTPS and basic privacy policies, it lacks cookie consent mechanisms and some security headers, indicating room for security and compliance improvements. No direct company contact emails or phone numbers are visible, but social media presence on Facebook is active. Overall, the site is moderately professional with good content quality and user engagement.

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

    • 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

      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"

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 holds a strong market position as the leading Czech gaming database, leveraging user-generated content and community interaction to maintain relevance. Its business model appears to be content-driven with revenue likely from advertising partnerships, including SSP Seznam. The target customers are Czech-speaking gamers interested in game reviews and ratings. The site shows steady growth indicators with active recent content and community participation. Partnerships with WebČesky.cz and CZIN.eu suggest a stable operational ecosystem. However, the absence of detailed business contact information and formal security policies may limit trust for some users.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, and Matomo analytics is configured to disable cookies, enhancing privacy. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No visible vulnerability disclosure or incident response information is provided, which could hinder timely security issue management. Forms exist for user login and registration but lack visible advanced security controls like CSRF tokens. Overall, the site would benefit from enhanced security policies, improved header configurations, and transparent incident response mechanisms to strengthen its security maturity.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and improve privacy transparency.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and incident response contact information to build user trust.
  4. Regularly update and audit JavaScript libraries to mitigate vulnerabilities.
  5. Enhance form security with CSRF protection and input validation to prevent injection attacks.

Technical notes

Notes

The website uses a custom-built CMS with JavaScript libraries such as jQuery, Thickbox, and Devrama Slider for UI components. Analytics are handled by Matomo with cookie disabling for privacy. Advertising is integrated via SSP Seznam and Toplist tracking pixels. The site is hosted likely by Czech providers WebČesky.cz and CZIN.eu. Performance is moderate with basic mobile optimization and accessibility features. SEO is well addressed with meta tags and structured navigation. Technical debt is moderate due to some outdated libraries and missing security headers. Opportunities exist to modernize the tech stack, improve mobile responsiveness, and enhance security configurations to reduce operational risks.
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.
