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

Médiář is a Czech online media publication focused on daily news about media, marketing, advertising, and PR industries. It serves professionals and agencies within the Czech media and marketing sectors by providing news, industry insights, job listings, and advertising galleries. The website is well-structured with a consistent brand presence and targets a specialized audience interested in media and marketing developments. Technically, the site is built on WordPress with a modern tech stack including Google Analytics, Facebook Pixel, and Seznam SSP ads, indicating a mature digital infrastructure. The site employs Google Consent Mode and cookie consent mechanisms to address privacy concerns, although an explicit privacy policy page was not found in the provided content. Security posture is good with HTTPS and some security best practices, but could be improved by adding explicit security headers and clearer incident response contacts. The absence of WHOIS data reduces domain transparency and slightly impacts trustworthiness, but the website content and technical setup suggest a legitimate and professional media outlet. Overall, the site scores well in content quality, technical implementation, and security, with room for improvement in privacy compliance and business credibility 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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Médiář holds a strong position as a specialized media and marketing news portal in the Czech Republic. Its business model revolves around content publication, advertising revenue, and industry networking through job listings and agency directories. The site leverages partnerships with major ad networks like Google Ad Manager and Seznam SSP, and integrates tracking and marketing tools for audience measurement and monetization. The target customers are media professionals, marketing agencies, PR firms, and advertisers. The site demonstrates growth potential through comprehensive industry coverage and active job market integration. However, the lack of visible company contact details and WHOIS transparency could be improved to enhance business credibility and trust. The platform's ecosystem includes partnerships with advertising and analytics providers, supporting its revenue streams and market reach.

Security posture

The website exhibits a moderate to good security posture with enforced HTTPS, use of Google Consent Mode for privacy, and cookie consent banners. It integrates third-party scripts responsibly with async and defer attributes to optimize performance and reduce risk. However, explicit security headers such as Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options are not clearly present, which are recommended to harden security. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site lacks visible incident response or security contact information, which is a gap in security readiness. Privacy compliance is partially addressed but could be enhanced with a clear privacy policy and terms of service. Overall, the site is secure for typical media publication use but should adopt additional best practices to improve resilience and compliance.

Recommendations

  1. Publish a comprehensive and accessible privacy policy page to improve GDPR compliance and user trust.
  2. Add explicit security headers such as Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options to enhance security posture.
  3. Provide clear contact information for security incidents and general inquiries to improve transparency and incident response readiness.
  4. Implement a security.txt file to facilitate vulnerability disclosure and improve security communication.
  5. Enhance accessibility features to meet modern standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with a modern technology stack including jQuery, Google Tag Manager, Google Analytics, Facebook Pixel, and Seznam SSP advertising scripts. It uses Google Fonts and Modernizr for enhanced UI/UX and compatibility. The site employs responsive design techniques and lazy loading for ads to optimize performance. SEO is supported by structured data (JSON-LD) and comprehensive meta tags including Open Graph and Twitter Cards. Performance is moderate with asynchronous script loading but could benefit from further optimization. Hosting provider details are not explicitly found. The site shows technical maturity suitable for a professional media publication but can improve accessibility and security header implementation to reduce technical risks.
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.
