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

iDNES.cz is a leading Czech news portal established in 1998, offering comprehensive news coverage, premium subscription content, video, weather, and ticket sales services. It operates under the parent company Mafra, a.s., and targets a broad general audience in the Czech Republic. The website demonstrates a mature digital infrastructure with integration of multiple advertising and analytics technologies, including Google Tag Manager, Gemius, and Piano paywall. Security posture is solid with HTTPS enforcement and consent management, though some security headers could be improved. The absence of WHOIS data limits domain registration trust assessment but the strong brand presence and business information support legitimacy. Overall, the site is professional, content-rich, and well-optimized for user experience and advertising monetization.

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

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

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 in Czech media, leveraging a mixed revenue model of advertising and premium subscriptions. It maintains partnerships with related media sites and ticketing platforms, enhancing its service offerings. The business model focuses on delivering timely news, specialized magazines, and interactive content such as quizzes and horoscopes. The company shows digital maturity with advanced ad tech and consent frameworks, indicating a focus on compliance and monetization. Growth potential lies in expanding premium content and maintaining user engagement through multimedia and interactive features.

Security posture

The website employs HTTPS and integrates consent management tools, reflecting compliance with privacy regulations. Use of reputable third-party analytics and advertising networks is evident. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not clearly present, representing an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policy information are not publicly available, which could be improved to enhance transparency and trust.

Recommendations

  1. Implement and enforce comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Enhance privacy policy visibility and detail to improve GDPR compliance perception.
  4. Regularly audit third-party scripts and ad networks for security and privacy risks.
  5. Improve accessibility features to meet higher standards and broaden audience reach.

Technical notes

Notes

The website uses a modern technology stack with multiple third-party integrations for analytics, advertising, and subscription management. Performance is moderate with good mobile optimization and SEO practices. The site uses asynchronous script loading and preloading for performance optimization. However, no specific CMS or hosting provider information was detected. Accessibility is basic and could be improved. The technical infrastructure supports a complex content delivery and monetization model but requires ongoing maintenance to mitigate risks from third-party dependencies.
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.
