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

TISCALI MEDIA, a.s. is a well-established Czech media company operating a broad portfolio of internet media and services that reach over 6.7 million users monthly. Their offerings include news portals, specialized content sites, email services, and file storage, supported by a parent company Dignity, s.r.o. The company demonstrates a strong market position with diversified media properties and a clear focus on advertising revenue. Technically, the website employs modern web technologies such as Bootstrap, Google Analytics, and Google Maps API, providing a responsive and user-friendly experience. However, the absence of visible privacy and cookie policies indicates a gap in privacy compliance. Security posture is moderate with HTTPS usage but lacks explicit security headers and published security policies. WHOIS data is unavailable, which slightly reduces trust from a domain registration perspective but does not detract from the professional presentation and business legitimacy. Overall, the website is professional, content-rich, and safe for general audiences, with room for improvement in privacy and security 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

11 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

      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 company holds a significant position in the Czech media market with a diverse portfolio targeting professionals, managers, and general media consumers. Their business model relies primarily on advertising revenue with plans for expanded monetization through newsletters and premium content. The integration of ARBOmedia as a subsidiary and ownership by Dignity, s.r.o. indicates a consolidated media group with strong market reach. The company actively manages multiple specialized media brands, enhancing its competitive advantage. Partnerships and media representation services further strengthen its ecosystem. The company’s clear contact information and professional content support credibility and trustworthiness.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the lack of security headers such as Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth. No incident response or security policies are published, and no vulnerability disclosure or security.txt files were found. The use of third-party scripts like Google Analytics and Google Tag Manager introduces tracking but no apparent vulnerabilities. Overall, the security posture is adequate for a media website but could be enhanced by implementing recommended headers, publishing security policies, and improving privacy compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Publish incident response and vulnerability disclosure policies to enhance transparency and trust.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and minimize tracking where possible.
  5. Consider publishing WHOIS data or using verified domain registration to improve domain trustworthiness.

The website uses a modern technology stack including Bootstrap for responsive design, Google Fonts for typography, Font Awesome for icons, Owl Carousel for interactive elements, and Google Maps API for location display. Analytics are handled via Google Analytics and Google Tag Manager, indicating moderate user tracking. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. Performance is moderate with asynchronous script loading. No CMS was explicitly detected. Hosting provider details are not available from the provided data. Accessibility is basic but could be improved with ARIA roles and enhanced keyboard navigation support.
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.
