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

Lidovky.cz is a prominent Czech news portal operated by MAFRA, a.s., offering a wide range of news, analyses, interviews, and premium content to a general audience interested in current affairs. The website demonstrates a mature digital infrastructure with integration of multiple advertising and analytics technologies, including Google Analytics, Gemius, and advanced consent management via Didomi. The site is well-designed with excellent content quality, clear navigation, and mobile optimization. Security posture is good with HTTPS enforced and consent mechanisms in place, though some improvements in security headers and incident response transparency are recommended. The absence of WHOIS data is a notable gap but does not detract significantly from the overall legitimacy given the strong business branding and content quality. Strategic recommendations include enhancing security headers, publishing vulnerability disclosure information, and improving accessibility features to further strengthen trust and compliance.

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

7 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

      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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

Lidovky.cz holds a strong market position as a leading Czech news media outlet under MAFRA, a.s. Its business model combines free news content with a premium subscription offering, targeting a broad demographic interested in news, economy, culture, and sports. The portal leverages partnerships within the MAFRA group, including idnes.cz, to expand reach and advertising revenue. The extensive use of advertising networks and tracking services indicates a monetization strategy reliant on ad revenues and user data analytics. The site maintains a professional editorial team and a diverse content portfolio, supporting sustained audience engagement and growth potential.

Security posture

The website exhibits a solid security foundation with HTTPS enforced and multiple consent management tools deployed to comply with GDPR. Tracking and advertising scripts are managed with user consent, reflecting good privacy practices. However, the lack of explicit Content-Security-Policy headers and absence of published incident response contacts represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is strong but could be enhanced by adopting additional security headers and transparency measures.

Recommendations

  1. Implement a robust Content-Security-Policy header to mitigate XSS and related attacks.
  2. Publish a security.txt file and incident response contact information to improve vulnerability disclosure and trust.
  3. Enhance accessibility features to meet higher standards and improve user experience for all users.
  4. Regularly audit third-party scripts and advertising technologies for security and privacy compliance.
  5. Maintain transparency in data retention policies and update privacy notices accordingly.

Technical notes

Notes

The website uses a modern JavaScript-heavy tech stack with integrations for analytics, advertising, and consent management. Technologies include Google Analytics, Google Tag Manager, Gemius tracking, Marfeel SDK for mobile optimization, and Prebid.js for header bidding in advertising. The site loads multiple external scripts asynchronously to optimize performance. The HTML structure is well-formed with meta tags for SEO and Open Graph for social sharing. Performance is moderate with room for improvement in caching and resource optimization. Mobile optimization is good, supported by responsive design and dedicated mobile version links. Accessibility is basic but could be improved with ARIA roles and enhanced keyboard navigation.
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.
