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

Atlas.cz is a Czech internet portal providing a variety of services including email, news, weather, and lifestyle content. It targets Czech-speaking users and offers a broad range of content, positioning itself as a significant media player in the Czech Republic. The website uses modern web technologies such as Next.js and React, supported by multiple third-party analytics and advertising services. The site is accessible without any WAF or security challenges, indicating good availability and user experience. However, the absence of WHOIS data and lack of explicit privacy and cookie policies slightly reduce trust and compliance scores. Overall, the site maintains a good security posture with HTTPS and modern practices but could improve transparency and privacy compliance.

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

8 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

Atlas.cz operates as a large-scale media portal in the Czech Republic, offering diversified content including news, email services, and weather updates. Its business model revolves around content aggregation and advertising revenue, leveraging partnerships with multiple ad networks and analytics providers. The portal targets a broad audience of Czech internet users seeking reliable and varied content. Despite the lack of publicly available WHOIS data, the domain is a subdomain of centrum.cz, a known Czech portal, which supports its legitimacy. The site’s technical infrastructure is modern and scalable, using CDN services and contemporary JavaScript frameworks. The portal’s market position is strong within the Czech media landscape, with consistent branding and good content quality.

Security posture

The website enforces HTTPS and uses modern security practices, including the use of security headers (though some could be improved). No exposed sensitive data or vulnerable libraries were detected. The site integrates multiple third-party scripts for analytics and advertising, which introduces some risk but is common for media portals. No incident response or security policy pages were found, indicating potential gaps in transparency. The site lacks explicit privacy and cookie policies, which is a compliance concern. Overall, the security posture is good but could be enhanced by adding comprehensive security headers and improving privacy disclosures.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Regularly audit third-party scripts and dependencies to mitigate risks from external services.
  4. Provide visible contact information and security incident response details to enhance transparency.
  5. Consider publishing WHOIS data or ensuring domain registration information is accessible to improve legitimacy perception.

Technical notes

Notes

The website is built on a modern tech stack featuring Next.js and React, delivering dynamic content efficiently. It uses a CDN (hpx-cdn.xsd.cz) for static assets, improving load times and scalability. Multiple third-party analytics and advertising scripts are integrated, including Gemius, Performax, and Facebook SDK. The site is mobile-optimized with responsive design and good SEO practices. Accessibility is basic but functional. Performance is moderate, with potential improvements in script loading and caching. No CMS was explicitly detected, suggesting a custom or headless CMS solution. Overall, the technical infrastructure supports a robust and scalable media portal but could benefit from enhanced accessibility and performance tuning.
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.
