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

Téma 21 is a newly established (2024) Czech media platform specializing in journalism, interviews, podcasts, and articles. It targets Czech and Slovak audiences interested in in-depth media analysis and current affairs. The website demonstrates a professional and modern design, leveraging technologies such as Tailwind CSS and Font Awesome, hosted via Websupport. GDPR compliance is well implemented with a clear cookie consent mechanism and privacy policy. However, explicit contact information and terms of service are not prominently available, which could be improved for better transparency. Security posture is good with HTTPS and some security best practices, though additional security headers and incident response details are recommended. Overall, the platform presents high-quality content with excellent user experience and trustworthy branding.

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

      Third-party services without privacy policy

      Detected services: Facebook, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 22 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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 platform operates in the media sector, focusing on quality journalistic content and multimedia formats like podcasts and videos. Its business model likely includes user support and advertising. The market position is niche but professional, aiming to provide insightful and analytical content. The company appears small but consistent in branding and content quality. The absence of detailed business contact info and certifications suggests a startup or small enterprise stage. The platform integrates social media verification and uses modern web technologies, indicating digital maturity. Growth potential exists through content expansion and enhanced user engagement.

Security posture

The website employs HTTPS and includes a cookie consent banner aligned with GDPR requirements, indicating a baseline security and privacy awareness. Security headers are not fully evident, and no explicit security or incident response policies are published. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a security.txt or vulnerability disclosure page limits transparency for security researchers. Overall, the security posture is moderate to good but could benefit from enhanced header policies, explicit incident response contacts, and regular security audits.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  2. Publish clear terms of service and incident response/contact security email addresses.
  3. Add a security.txt file to facilitate vulnerability reporting.
  4. Enhance transparency by providing official contact emails and phone numbers for business and security inquiries.
  5. Regularly review third-party scripts and dependencies for vulnerabilities and update them accordingly.

Technical notes

Notes

The website uses a modern frontend stack with Tailwind CSS for styling, Font Awesome for icons, and Google Fonts for typography. It is hosted on Websupport infrastructure, as indicated by the nameservers. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with some reliance on external CDNs for fonts and scripts. No CMS is explicitly detected, suggesting a custom or static site generator approach. SEO is supported by proper meta tags and canonical links. Technical risks are minimal but include the need for improved security headers and formalized security policies.
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.
