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

  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"

    • 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

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The website positions itself as a niche media outlet in the Czech Republic, focusing on infotainment content. Its competitive advantage lies in diverse content categories including science, culture, history, and travel, appealing to a broad audience. Revenue streams are primarily advertising-based, supplemented by newsletter subscriptions. The site integrates with major ad networks and tracking platforms, indicating a mature marketing ecosystem. No direct business contact information or certifications were found, which is typical for content publishers. The lack of WHOIS data limits deeper business verification. Growth indicators include active content updates and integration of modern web technologies.

Security posture

The security maturity level is moderate. The site uses HTTPS, which is mandatory, and employs asynchronous loading of scripts to improve performance and security. However, it lacks several important security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which could mitigate common web attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Forms use HTMX for live search but no explicit CSRF tokens or anti-abuse mechanisms were visible. There is no public incident response or security policy information. GDPR compliance is partial, with cookie consent but no clear privacy policy. Overall, the site should improve security headers and formalize privacy and incident response policies to enhance trust and compliance.

Recommendations

  1. Implement comprehensive privacy policy page clearly accessible from the homepage.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Conduct regular security audits of third-party scripts and dependencies.
  4. Establish and publish incident response and vulnerability disclosure policies.
  5. Enhance privacy compliance by detailing data collection, retention, and user rights.

Technical notes

Notes

The website uses a modern tech stack with JavaScript, Tailwind CSS for styling, and HTMX for dynamic content loading. It integrates with multiple third-party services for advertising, tracking, and newsletter management. The site is mobile-optimized with responsive design and good SEO practices including structured data (JSON-LD) and Open Graph tags. Hosting appears to leverage CDN services for media delivery. Performance is moderate, with asynchronous script loading and preconnect hints. Accessibility is basic but could be improved with more ARIA attributes and semantic HTML. There is no detected CMS, suggesting a custom or headless solution. Technical risks include reliance on multiple third-party scripts which may introduce vulnerabilities if not managed properly.
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.
