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

Volny.cz is a Czech internet portal providing email services, news, weather, and various online content primarily targeting Czech-speaking users. The site is professionally designed using modern web technologies such as Next.js and React, hosted on infrastructure likely related to Seznam.cz. The portal integrates multiple third-party analytics and social media SDKs, including Gemius, Facebook, Twitter, and YouTube. Despite the lack of WHOIS data from the CZ.NIC registry, the website appears legitimate and well-established in the Czech media landscape. However, the absence of explicit privacy and cookie policies and missing security headers indicate areas for improvement in compliance and security transparency.

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

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

Volny.cz operates as a large-scale media portal in the Czech Republic, offering a mix of email services and editorial content. Its business model is primarily advertising-supported, leveraging user engagement through news and lifestyle articles. The portal benefits from the backing of a major Czech internet company, likely Seznam.cz, which provides hosting and CDN services. The site targets a broad audience of Czech internet users seeking reliable news and communication services. While the portal maintains a consistent brand and good content quality, the lack of visible contact information and privacy documentation may affect user trust and regulatory compliance.

Security posture

The website uses HTTPS and modern web frameworks, which is positive for security. However, no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected in the provided content. The presence of multiple third-party scripts introduces potential risk vectors if not properly managed. There is no public security policy or incident response information available, which limits transparency. The missing WHOIS data also raises questions about domain registration legitimacy. Overall, the security posture is moderate but could be enhanced by implementing standard security headers, publishing security policies, and ensuring third-party script integrity.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Provide clear contact information including security incident response contacts to improve transparency.
  4. Regularly audit and monitor third-party scripts to mitigate supply chain risks.
  5. Investigate and resolve the missing WHOIS data issue to strengthen domain legitimacy and trust.

Technical notes

Notes

The website is built on a modern React/Next.js stack, leveraging server-side rendering and CDN delivery for performance. It uses multiple CSS stylesheets and asynchronous JavaScript chunks for modular loading. The site integrates external SDKs for privacy management, analytics, and social media widgets. Hosting appears to be on a CDN associated with Seznam.cz, a major Czech internet provider. Performance is moderate with good mobile optimization and SEO metadata present. Accessibility features are basic but could be improved. The technical infrastructure is solid but would benefit from enhanced security configurations and clearer compliance documentation.
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.
