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

JOJ.cz is a regional media broadcaster specializing in Czech and Slovak films and TV programming. The website offers a rich schedule of film content across multiple channels and genres, targeting film enthusiasts and general audiences interested in regional cinema. The business model centers on broadcasting and online streaming, positioning JOJ.cz as a key player in the Czech media landscape with a mature domain presence since 2007. Technically, the site employs modern web technologies including asynchronous loading of Google Tag Manager and Google Analytics scripts, lazy loading of images, and responsive design elements, providing a good user experience across devices. However, the site lacks visible privacy and cookie policies, contact information, and security headers, which are important for compliance and trust. The security posture is moderate with HTTPS enabled but could be improved by adding security headers and formal incident response contacts. Overall, the site is safe for general audiences and professionally designed, but improvements in privacy compliance and security transparency are recommended.

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

6 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

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

JOJ.cz operates in the media sector, focusing on Czech and Slovak film content distribution. Its competitive advantage lies in exclusive regional content and a multi-channel approach including JOJ Family and JOJ Cinema partnerships. The business model likely includes advertising revenue and possibly subscription or content licensing. The target customers are regional film fans and general TV audiences. The domain age and consistent branding indicate stability and market presence. Partnerships with related domains such as jojfamily.blesk.cz and jojcinema.cz enhance content diversity and reach. Growth indicators include a comprehensive program schedule and use of modern analytics tools. Strategic observations suggest a need to enhance compliance and security transparency to maintain trust and regulatory alignment.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, and tracking scripts are loaded asynchronously to reduce performance impact. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No visible contact channels for incident response or vulnerability disclosure are present, which may delay response to security issues. Privacy and cookie policies are missing, indicating potential compliance gaps with GDPR and other privacy regulations. No vulnerable libraries or exposed sensitive data were detected in the provided content. To improve security posture, the organization should implement security headers, publish privacy and cookie policies with consent mechanisms, and provide clear incident response contacts.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against web vulnerabilities.
  3. Provide clear contact information including emails and phone numbers for general and security-related inquiries to improve transparency and trust.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable components.

Technical notes

Notes

The website uses a modern tech stack including HTML5, CSS3, JavaScript, and lazy loading for images to optimize performance. Google Tag Manager and Google Analytics are integrated asynchronously, indicating attention to performance and analytics needs. The site is mobile optimized with responsive design elements. However, no CMS or backend platform was explicitly detected. Hosting provider details are not available from the provided data. Performance is moderate, with potential for improvement by optimizing resource loading and caching. Accessibility features are basic, with room for enhancement to meet WCAG standards. SEO optimization is basic, with canonical links and Open Graph tags present but no structured data like JSON-LD detected. Overall, the technical infrastructure supports a professional media website but could benefit from modernization in accessibility and SEO practices.
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.
