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

MAFRA, a.s. is a prominent Czech media group operating a diverse portfolio of traditional and digital media assets including newspapers, internet portals, television, radio, and printing services. The company targets a broad general audience in the Czech Republic and maintains a strong market position with well-known brands such as MF DNES and iDNES.cz. The website reflects a professional media publishing business model focused on content distribution and advertising revenue. Technically, the site employs a mix of legacy and modern web technologies including jQuery, Google Analytics, Google Tag Manager, and advanced consent management platforms like Didomi and Piano for GDPR compliance. While the site is well-structured and mobile-optimized, some technical debt is evident with older library versions and missing security headers. Security posture is moderate with HTTPS enforced and consent mechanisms in place, but lacks published security policies or incident response contacts. The absence of WHOIS data suggests privacy protection, which is typical for media companies. Overall, the site is trustworthy and professionally maintained with room for security and technical improvements.

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.

      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

MAFRA operates in the media sector with a large company size and a comprehensive portfolio spanning print, digital, and broadcast media. Its business model leverages content creation, subscription services, and advertising. The company has subsidiaries such as Mafra print and Mafra Slovakia, and partners with regional and magazine publishers. The website's integration of paywall and subscription technologies indicates a focus on monetizing digital content. The presence of multiple tracking and advertising technologies reflects a mature marketing ecosystem. The company maintains a clear legal presence with registration details and physical address disclosed, enhancing credibility. Growth opportunities may lie in modernizing technology stacks and expanding digital subscription offerings.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and comprehensive cookie consent management aligned with GDPR requirements. However, the use of an outdated jQuery version may expose the site to known vulnerabilities. The absence of key security headers such as Content Security Policy and HSTS reduces defense-in-depth. No explicit security policy or incident response contact information is published, which limits transparency and preparedness. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from publishing a security policy, implementing security.txt, and updating libraries to enhance security posture and compliance.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Continue enhancing privacy compliance by regularly auditing consent mechanisms and data processing disclosures.

Technical notes

Notes

The website uses a combination of legacy and modern web technologies, including jQuery 1.12.0, Google Analytics, Google Tag Manager, Gemius tracking, and advanced consent management platforms like Didomi and Piano. The site is mobile-optimized with responsive design and good SEO metadata. Performance is moderate, with room for improvement by updating scripts and optimizing loading. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Accessibility features are basic but present. The site uses multiple external domains for tracking and advertising, which are managed with user consent. Overall, the technical infrastructure supports a professional media publishing operation but would benefit from modernization and enhanced security controls.
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.
