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

MAFRA, a.s. is a large, established media group based in the Czech Republic, offering a broad portfolio of traditional and digital media services including printed newspapers, internet media, television, radio, and printing services. The company targets a general audience with a focus on quality journalism and entertainment, leveraging a strong market position in the Czech media landscape. The website reflects a professional and consistent brand image with comprehensive content about the company and its offerings. Technically, the site employs a mature technology stack including jQuery, Google Analytics, Gemius tracking, and advanced consent management tools such as Didomi and Piano for subscription services. The site is mobile optimized and demonstrates good SEO and accessibility practices. Security-wise, the site uses HTTPS and consent mechanisms but lacks explicit security headers and published incident response policies, indicating room for improvement in security transparency and hardening. The absence of WHOIS data reduces domain trust slightly, but the overall business credibility and website professionalism remain high.

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

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 diversified portfolio spanning print, digital, TV, and radio. Its business model centers on content publishing and advertising revenue, supported by subscription services managed via Piano. The company maintains subsidiaries such as Mafra print and Mafra Slovakia, indicating regional expansion. The website's integration of multiple advertising and tracking platforms suggests a strong focus on monetization and audience analytics. The presence of detailed privacy and cookie policies with consent management aligns with GDPR compliance, enhancing trust with European users. The company targets a broad demographic, including general news consumers and advertisers. The lack of visible contact emails or phone numbers on the main page may indicate a preference for controlled communication channels or internal contact management.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and consent management implemented. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests potential vulnerabilities to common web attacks. No security.txt or incident response contact information is published, which limits transparency and readiness perception. The use of multiple third-party tracking and advertising scripts increases the attack surface and privacy risks, though these are managed with consent tools. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate for a media company but could be enhanced by adopting additional security best practices and publishing clear security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party libraries and tracking scripts to minimize vulnerabilities.
  4. Enhance accessibility features to meet higher standards and improve user experience for all audiences.
  5. Consider adding visible and verified contact channels such as company emails and phone numbers to improve business credibility.

Key observations

  1. Website is fully accessible with no blocking or WAF challenges.
  2. Content is professional and consistent with a major Czech media group.
  3. Privacy and cookie policies are present and include consent mechanisms.
  4. No contact emails or phone numbers explicitly found in the HTML content.
  5. WHOIS data is unavailable, which is unusual but not necessarily suspicious for a media company.
  6. Multiple external tracking and advertising scripts are used, indicating extensive user tracking.
  7. No security.txt or explicit security policy pages found.
  8. No forms detected in the provided HTML content.
  9. Website uses HTTPS and modern tracking/consent technologies.
Technical notes

Notes

The website uses a mature but somewhat dated JavaScript library (jQuery 1.12.0) alongside modern tracking and consent management tools such as Didomi and Piano. The site loads multiple external scripts for analytics, advertising, and subscription management, indicating a complex digital ecosystem. Performance is moderate with room for optimization, especially given the number of external resources. Mobile optimization is good, and SEO meta tags are well implemented. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not available from the HTML content. The site could benefit from modernization of its JavaScript libraries and optimization of third-party script loading to improve speed and reduce technical debt.
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.
