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

MediaGuru.cz is a Czech online media platform focused on delivering news, interviews, and resources related to media, advertising, and marketing. It serves professionals and enthusiasts in the Czech media industry by providing up-to-date articles, event information, and a media dictionary. The website demonstrates a consistent brand presence and maintains active social media channels to engage its audience. Technically, the site uses modern analytics tools such as Google Analytics, Microsoft Application Insights, and Gemius, and is hosted on Azure CDN, ensuring moderate performance and good mobile optimization. Security posture is solid with HTTPS enforced and consent mechanisms for tracking, but lacks explicit security headers and published privacy or cookie policies. The absence of WHOIS data reduces trust verification, but the website content and infrastructure indicate a legitimate media portal. Strategic improvements include publishing comprehensive privacy and cookie policies, adding security headers, and providing clear contact information for security and data protection matters.

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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

    • 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

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

MediaGuru.cz occupies a niche in the Czech media and marketing news sector, offering a mix of news articles, interviews, and event listings. Its business model revolves around content provision and advertising revenue, supported by partnerships with advertising networks and media agencies. The platform targets media professionals, marketers, and industry observers, positioning itself as a reliable source for media-related insights. The website's integration with major analytics and marketing tools suggests a data-driven approach to audience engagement and monetization. While the domain's WHOIS data is unavailable, the site's active content updates and social media presence indicate ongoing operations and market relevance.

Security posture

The website enforces HTTPS and employs modern tracking and analytics tools with consent defaults that deny tracking until user approval, reflecting awareness of privacy regulations. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security policies or incident response contacts indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The site would benefit from implementing a security.txt file and publishing clear data protection officer contact details to enhance incident response readiness and compliance transparency.

Recommendations

  1. Publish comprehensive privacy and cookie policies clearly accessible from the website.
  2. Implement and enforce security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Provide explicit contact information for security incidents and data protection officer details.
  4. Add a security.txt file to facilitate vulnerability disclosure and incident reporting.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize tracking without consent.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics, Google Tag Manager, Microsoft Application Insights, and Gemius for analytics and tracking. It leverages Azure CDN for content delivery, contributing to moderate performance and good mobile responsiveness. The site employs asynchronous and deferred script loading to optimize page load times. SEO is supported by proper meta tags and Open Graph data, although accessibility features are basic. No CMS was explicitly detected. The site could improve by enhancing accessibility and adding more robust SEO and security configurations.
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.
