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

Classic Praha is a Czech classical music radio station operated by Seznam.cz, a major internet company in the Czech Republic. The station broadcasts classical, film, jazz, swing, and musical music primarily in Prague on 98.7 FM and also offers online streaming and a mobile app. The website provides cultural news, program schedules, and multimedia content to its audience. Technically, the site uses modern JavaScript libraries, Google Analytics, Gemius tracking, and a consent management platform to comply with privacy regulations. The site is well-structured, mobile-optimized, and uses HTTPS for secure communications. However, the absence of WHOIS data reduces transparency and trust slightly. No direct contact emails or phone numbers are visible, and there is no explicit security or incident response policy published. Overall, the website is professional, content-rich, and trustworthy, with moderate tracking and advertising integration.

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.

Priority findings

9 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

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

Classic Praha holds a strong position in the Czech media market as a specialized classical music broadcaster under the umbrella of Seznam.cz. Its business model relies on advertising revenue through Seznam's SSP network and digital streaming services. The target audience includes classical music enthusiasts in Prague and online listeners interested in cultural programming. The website supports brand engagement through social media channels and mobile app promotion. While the site lacks detailed business contact information, its association with Seznam.cz lends credibility. The presence of multiple advertising and tracking technologies indicates a mature digital marketing approach. Growth opportunities may include expanding digital content and enhancing user interaction.

Security posture

The website demonstrates a good security posture with enforced HTTPS and use of modern tracking and analytics scripts loaded asynchronously. The integration of a consent management platform indicates awareness of privacy compliance requirements. However, the absence of visible security headers such as Content-Security-Policy or X-Frame-Options is a gap. No explicit security policies or incident response contacts are published, which limits transparency in security governance. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the site is secure for typical user interactions but could improve by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a detailed security policy and incident response plan accessible from the website footer.
  2. Add and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear company contact information including support emails and phone numbers to improve trust and user support.
  4. Regularly audit third-party scripts and tracking technologies to minimize privacy risks and improve compliance.
  5. Enhance transparency by ensuring WHOIS data is available or justified if privacy protection is used.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of analytics and advertising scripts from Google, Gemius, and Seznam's SSP network. It employs a consent management platform for cookie compliance and promotes its mobile app via SmartBanner. The site is mobile-optimized with responsive design and uses standard meta tags for SEO and social sharing (Open Graph). No CMS or hosting provider details are explicitly detectable. Performance appears moderate with multiple third-party scripts which may impact load times. Accessibility features are basic but present. The site could benefit from enhanced technical documentation and security header implementation to reduce technical debt and improve resilience.
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.
