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

Mujsoubor.cz is a Czech-based software and game download portal operated by Internet Info, s.r.o., established in 2011. The website offers a broad range of downloadable programs and games, complemented by articles and guides targeting Czech-speaking technology and gaming enthusiasts. The business model relies primarily on advertising revenue, supported by Google Adsense and other ad networks, with user consent managed via a Didomi consent platform. The site demonstrates a moderate level of digital maturity with a modern tech stack including Bootstrap and jQuery, though some components like jQuery are outdated. Mobile optimization and user experience are good, with clear navigation and relevant content. Security posture is adequate with HTTPS enforced and consent mechanisms in place, but lacks explicit security headers and published security policies. Privacy compliance is partial, as no dedicated privacy policy or terms of service pages were found in the provided content. WHOIS data confirms the domain's legitimacy and consistent registration details. Overall, the site is functional, safe, and moderately trustworthy but could improve 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

8 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

    • 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

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

Mujsoubor.cz holds a stable position in the Czech software download market, leveraging a long-established domain and a wide content offering. Its competitive advantage lies in localized content and a comprehensive category structure catering to diverse user interests in software and gaming. Revenue streams are primarily advertising-based, with no direct e-commerce or subscription services evident. The target audience includes Czech-speaking users seeking software downloads and technology information. The partnership ecosystem includes advertising and tracking providers such as Google and Gemius. Growth indicators include regular content updates and active user engagement through forums and Q&A. Strategic observations suggest opportunities to enhance trust by publishing clear privacy and security policies and expanding contact transparency.

Security posture

The website maintains a basic to moderate security posture with HTTPS enabled and integration of consent management for GDPR compliance. Key strengths include the use of reCAPTCHA and established ad networks with privacy controls. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options reduces defense-in-depth. The use of an outdated jQuery version poses a potential vulnerability risk. No incident response or vulnerability disclosure information is publicly available, indicating a gap in security transparency. Data protection practices are partially implemented through consent banners but lack comprehensive documentation. Incident response readiness and security culture indicators are not evident from the content. Overall, the site is functional but would benefit from enhanced security best practices and compliance documentation.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Update all JavaScript libraries, especially jQuery, to the latest secure versions.
  4. Provide clear and accessible contact information including support and security contacts.
  5. Establish and publish a vulnerability disclosure policy or security.txt file to improve security transparency.

Technical notes

Notes

The website uses a combination of Bootstrap 3.3.7, jQuery 3.2.1, Font Awesome, and various advertising and analytics scripts including Google Analytics, Google Adsense, and Gemius. The site is mobile-optimized with responsive design and includes a consent management platform (Didomi) for GDPR compliance. Performance is moderate, with asynchronous loading of scripts and preconnect hints for external resources. The CMS is not explicitly identified, suggesting a custom or proprietary solution. Technical risks include the use of outdated JavaScript libraries and missing security headers. Opportunities exist to modernize the tech stack, improve accessibility features, and enhance SEO metadata. Overall, the technical infrastructure supports the business needs but requires updates to maintain security and performance.
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.
