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.

    • 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

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • 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

Deník Referendum operates as a donation and partner-supported media platform, targeting Czech readers interested in politics, society, and climate issues. It maintains a niche position in the Czech media landscape, emphasizing transparency and independence. The business model relies on public donations and partner support rather than paywalls or advertising revenue alone. The website content includes news, opinion pieces, podcasts, and investigative reports. The organization appears small but consistent in branding and content quality, with no evidence of parent or subsidiary companies. The site leverages multiple third-party analytics and advertising networks to support its operations.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of Cloudflare Bot Management to mitigate automated threats. Cookie consent is implemented with detailed categories, enhancing user privacy control. Security headers such as cache-control and pragma are present, though no explicit security policy or incident response contacts are published. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party scripts introduces some risk, but no known vulnerable libraries were identified. Recommendations include publishing a security policy, incident response contacts, and a security.txt file to improve transparency and vulnerability management.

Recommendations

  1. Publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Add a terms of service page to clarify user rights and obligations.
  3. Provide clear contact information including emails and phone numbers for general and security inquiries.
  4. Implement and publish a security policy and incident response contact details.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern JavaScript framework (Svelte) for frontend rendering, combined with multiple analytics and tracking services including Google Analytics, Hotjar, Snowplow, and Plausible. Cookie consent is managed by CookieYes, providing granular user control. Hosting appears to be behind Cloudflare, leveraging its Bot Management service. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved. No CMS was explicitly detected, suggesting a custom or proprietary solution. The site uses multiple external domains for scripts and ads, which should be monitored for security and privacy compliance.
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.
