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

  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 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 company holds a strong market position in the Czech media sector, leveraging multiple magazine brands and partnerships to diversify content and revenue streams. Its business model centers on digital news publishing complemented by print magazine subscriptions and advertising revenue. The target audience is broad, encompassing general Czech-speaking readers interested in current events and cultural topics. The presence of partner domains and e-commerce for subscriptions indicates a well-integrated ecosystem. Growth indicators include frequent content updates and diversified media offerings. Strategic observations suggest opportunities to enhance transparency in security and incident response communications to further build trust.

Security posture

The website employs robust security measures including HTTPS, modern security headers, and cookie consent management, indicating a mature security posture. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of a publicly accessible security policy or incident response contact limits transparency and preparedness communication. There is no evidence of vulnerability disclosure programs or security.txt files, which are recommended best practices. Overall, the security maturity is good but could be improved by formalizing and publishing security governance documents and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly review and audit third-party scripts and advertising integrations for security risks.
  5. Enhance transparency on data retention and privacy practices to strengthen GDPR compliance and user trust.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring good performance and mobile responsiveness. It uses advanced image optimization and lazy loading techniques for efficient content delivery. Integration with Google Adsense and Tag Manager supports monetization and analytics. The site structure is clear with well-defined navigation and semantic HTML elements, supporting SEO and accessibility. No CMS was explicitly detected, suggesting a custom or proprietary content management system. Hosting provider details are not evident from the HTML content. Performance is moderate with room for optimization in script loading and caching strategies. Overall, the technical infrastructure supports a high-quality user experience with opportunities for further optimization and security enhancements.
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.
