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

Mediachannel is a Czech Republic based media and brand marketing service provider established in 2007. The company focuses on helping brands grow by improving customer interaction and integrating real-world and digital experiences. Their website reflects a professional and consistent brand image targeting businesses seeking media and brand development services. Technically, the site uses modern technologies including JW Player for media, Google Analytics and Tag Manager for tracking, and is built on the Jekyll framework. The website is mobile optimized and SEO friendly with good design and navigation. Security posture is moderate with HTTPS enabled and cookie consent implemented, but lacks visible security headers and formal privacy or terms policies. No contact information or incident response channels are explicitly provided, which limits transparency. Overall, the domain age and WHOIS data support legitimacy and trustworthiness. Strategic improvements in security headers, privacy documentation, and contact transparency would enhance compliance and trust.

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

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

  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

      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

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

Mediachannel operates in the media sector with a focus on brand growth and customer engagement. Their business model centers on providing media and brand services to other businesses, likely generating revenue through service contracts. The company targets Czech businesses and brands, leveraging digital media integration. The website's consistent branding and content quality indicate a stable market position. The use of analytics and marketing tools suggests a data-driven approach to client engagement. Absence of detailed contact info and certifications limits visible trust signals but the long domain age and active social media presence support credibility. No partnerships or subsidiaries are explicitly indicated.

Security posture

The website enforces HTTPS with a valid SSL certificate, which is a fundamental security measure. Cookie consent is implemented, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No forms or input fields are present, minimizing attack surface. No vulnerability disclosures or incident response contacts are provided, which is a gap in security transparency. The use of third-party libraries like JW Player and jQuery is current but should be regularly audited for vulnerabilities. Overall, the security posture is moderate but can be improved by adding security headers, formal policies, and incident response mechanisms.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  2. Publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  3. Add clear contact information including emails and phone numbers for general and security incident reporting to enhance transparency and responsiveness.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance cookie consent mechanism with detailed information on data retention and user rights to align with GDPR and other privacy regulations.

Technical notes

Notes

The website is built using the Jekyll static site generator, which provides a lightweight and secure platform. It uses JW Player for video content delivery, Google Analytics and Tag Manager for user tracking and analytics, and jQuery and Anime.js for frontend interactivity and animations. The site loads external scripts asynchronously to improve performance. The design is responsive and optimized for mobile devices. SEO is supported by proper meta tags including Open Graph and Twitter Cards. No CMS vulnerabilities are apparent due to static site nature. Hosting provider details are not explicitly found. Performance is moderate with some external dependencies. Accessibility is basic but could be improved with more ARIA roles and semantic HTML. Overall, the technical infrastructure is modern and stable with room for optimization in accessibility and security headers.
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.
