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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

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

  2. Security headers

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

Deník N operates in the media sector with a subscription and advertising revenue model. It targets the Czech general public with independent news content. The company leverages partnerships with advertising networks like Google DoubleClick and uses consent management tools to comply with privacy regulations. The business model focuses on quality journalism supported by subscriptions, which suggests a sustainable revenue stream. The absence of parent or subsidiary companies in the data indicates an independent operation. The company maintains active social media channels to engage its audience and enhance its market presence.

Security posture

The website employs HTTPS with good SSL configuration and uses consent management via Didomi, reflecting awareness of privacy and security best practices. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the HTML content, representing an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site lacks publicly disclosed security policies or incident response contacts, which could be enhanced to improve transparency and readiness. Overall, the security posture is solid but could benefit from additional hardening and disclosure.

Recommendations

  1. Implement and enforce Content-Security-Policy and other security headers to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency and trust.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built on WordPress with a custom theme and integrates multiple third-party services including Google Analytics, Google Tag Manager, OneSignal for notifications, and Didomi for consent management. Advertising is managed through Google DoubleClick and Protag networks. The site uses modern JavaScript libraries and asynchronous script loading to optimize performance. Mobile optimization is good, and SEO meta tags are properly configured. Hosting provider details are not explicit, but the domain uses REG-WEBGLOBE registrar. Performance is moderate, with opportunities to improve load times by optimizing third-party scripts and caching strategies. The technical stack is modern and well-maintained, supporting the business goals effectively.
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.
