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

cdr.cz is a well-established Czech IT news portal founded in 1998, providing curated technology, security, AI, space, and gaming news to IT professionals and enthusiasts. The website operates on Drupal CMS and employs a modern tech stack including jQuery, Foundation CSS, and various advertising and analytics tools. While the site is mobile optimized and uses structured data for SEO, it lacks explicit privacy and cookie policies, which impacts its privacy compliance score. Security posture is generally good with HTTPS and some security headers, but incident response and vulnerability disclosure information are absent. Overall, the site is credible and professional but could improve transparency and compliance aspects.

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

cdr.cz holds a strong position in the Czech IT media market with a consistent brand and regular content updates. Its business model relies on advertising revenue through Google Adsense and OpenX. The target audience includes IT professionals and technology enthusiasts. The site features job listings and community blogs, indicating engagement beyond news. No parent or subsidiary companies were identified. The domain age and WHOIS data support legitimacy and trustworthiness.

Security posture

The website enforces HTTPS and uses standard security headers, but lacks visible security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party scripts introduces potential risk vectors, necessitating regular audits. Absence of security.txt or vulnerability disclosure reduces transparency. Privacy compliance is weak due to missing policies and consent mechanisms.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms.
  2. Add a security policy and incident response contact information accessible to users.
  3. Implement a security.txt file to facilitate vulnerability reporting.
  4. Audit and minimize third-party scripts to reduce attack surface.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The site uses Drupal CMS with a combination of jQuery, Foundation CSS, and various JavaScript libraries for UI components like sliders and modals. Google Analytics and Tag Manager are used for tracking, alongside Gemius for Czech market analytics. Advertising is managed via Google Adsense and OpenX (Revive Adserver). The site is mobile responsive and SEO optimized with structured JSON-LD data. Performance is moderate, with room for optimization. Hosting provider is not explicitly identified but appears to be Czech-based. No critical technical issues were found.
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.
