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

Seznam Zprávy is a prominent Czech news media platform operated by Seznam.cz, a leading internet company in the Czech Republic. The website offers a wide range of news content including articles, videos, podcasts, and publicistic reports targeting Czech-speaking audiences interested in current affairs, business, technology, and culture. The platform maintains consistent branding and provides author attribution, enhancing its credibility and trustworthiness in the media sector. Technically, the site employs modern JavaScript frameworks, supports the latest ECMAScript standards, and optimizes performance with lazy loading and preconnect strategies. Mobile optimization and accessibility features are well implemented, ensuring a good user experience across devices. Security posture is solid with HTTPS enforced and some security headers present, though improvements such as explicit Content Security Policy and additional security headers are recommended. Privacy compliance is basic, with no explicit privacy or cookie policies detected in the provided content snapshot, which should be addressed to meet regulatory standards fully. The absence of WHOIS data reduces domain trust slightly but is likely due to registry privacy policies rather than malicious intent. Overall, Seznam Zprávy represents a mature, professional news outlet with a strong market position in Czech media.

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.

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

Seznam Zprávy operates as a key media entity within the Czech Republic, leveraging the parent company Seznam.cz's extensive internet ecosystem. Its business model focuses on delivering timely news and multimedia content to a broad Czech audience, monetized through advertising networks such as Sklik and native advertising. The platform's competitive advantage lies in its integration with Seznam.cz services and its reputation for quality journalism. The target customers are Czech internet users seeking reliable news and analysis. Growth indicators include active content updates, diverse content formats, and engagement through podcasts and newsletters. Partnerships appear focused on internal Seznam domains and advertising networks. Strategic observations suggest continued investment in technical modernization and enhanced privacy compliance will support sustained market leadership.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS usage and partial implementation of security headers. The use of crossorigin attributes on fonts and scripts indicates attention to resource integrity and CORS policies. Error reporting mechanisms are in place to capture client-side issues. However, the lack of explicit Content Security Policy and other headers like X-Frame-Options and X-XSS-Protection represents a compliance gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policy information are not publicly available, which limits transparency. The site would benefit from publishing a security policy and vulnerability disclosure program to enhance trust and compliance with GDPR and NIS2 directives.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add explicit Content Security Policy and other recommended security headers to strengthen web security.
  3. Publish a security policy and incident response contact information to increase transparency and trust.
  4. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance contact information availability, including official company emails and phone numbers, to improve business credibility.

Technical notes

Notes

The website uses a modern JavaScript-based front-end framework (IMA) with Webpack bundling and supports the latest ECMAScript 2024 features, indicating a high level of technical maturity. Performance optimizations include lazy loading of images, font preloading, and preconnect hints to reduce latency. The site is mobile-optimized with responsive design and accessibility considerations. No CMS was explicitly detected, suggesting a custom or proprietary content management solution. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure supports fast loading times and a good user experience, though continuous monitoring for library vulnerabilities and security header enhancements is advised.
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.
