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

iDNES.cz is a leading Czech news media portal established in 1998, offering comprehensive news coverage, premium subscription content, video, weather, and magazine sections. It operates under the parent company Mafra, a.s., and targets a general audience in the Czech Republic. The website demonstrates a mature digital infrastructure with modern analytics, advertising, and consent management technologies. Security posture is solid with HTTPS and consent frameworks, though explicit security headers could be improved. The absence of WHOIS data limits domain trust verification but the website's content and structured data strongly indicate legitimacy. Overall, iDNES.cz is a professional, well-branded media platform with good privacy compliance and extensive content offerings.

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.

      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

The portal holds a strong market position as a major Czech news source with diversified content including local and international news, sports, culture, and premium articles. Its business model combines free content with a paid premium subscription. The company leverages partnerships with other media sites like Expres.cz and Lidovky.cz. Revenue streams likely include advertising, premium subscriptions, and sponsored content. The target audience is broad, encompassing general news consumers in the Czech Republic. The use of advanced ad tech and analytics indicates a data-driven approach to audience engagement and monetization.

Security posture

The website employs HTTPS and integrates GDPR-compliant consent management via Didomi and Piano. It uses reputable third-party analytics and advertising services with user consent. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, some security headers like X-Frame-Options and X-Content-Type-Options are not explicitly present and should be implemented to enhance protection against clickjacking and MIME sniffing. The site shows good security hygiene but could benefit from regular audits of third-party scripts and enhanced accessibility compliance.

Recommendations

  1. Implement and verify security headers such as X-Frame-Options and X-Content-Type-Options.
  2. Conduct regular security audits of third-party JavaScript libraries and ad networks.
  3. Enhance accessibility features to meet WCAG standards for broader compliance.
  4. Publish a clear and accessible terms of service page to improve transparency.
  5. Maintain updated WHOIS information or provide public registrant data to improve domain trust.

Technical notes

Notes

The site uses a modern JavaScript-heavy front end with integration of multiple third-party services including Google Tag Manager, Gemius analytics, Adform advertising, and Piano subscription management. Consent management is handled by Didomi, ensuring GDPR compliance. The site loads multiple CSS and JS resources from trusted domains, indicating a modular and scalable architecture. Performance is moderate with room for optimization. Mobile optimization is good, but accessibility is basic and could be improved. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD data. No CMS was explicitly detected from the HTML content.
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.
