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

Kurzy.cz is a Czech financial information portal providing real-time currency exchange rates, stock market data, commodity prices, and economic news. It targets investors, traders, and the general public interested in financial markets and investment insights. The website offers a broad range of financial data including domestic and international stock indices, currency rates, and commodity charts, supported by frequent news updates authored by financial experts and partners. Technically, the site employs a modern tech stack including jQuery, Google Fonts, Google Tag Manager, Facebook Pixel, and Gemius analytics. It uses HTTPS with good SSL configuration and asynchronous loading of scripts to optimize performance. The site has basic mobile optimization and accessibility features, with room for improvement in security headers and explicit privacy documentation. From a security perspective, the website is accessible without WAF or security challenges, uses HTTPS, and implements cookie consent mechanisms aligned with GDPR requirements. However, it lacks explicit privacy and terms of service pages, and no contact or incident response information is publicly available. The absence of WHOIS data limits domain trust assessment, but the website content and structure indicate a legitimate and professional operation. Overall, Kurzy.cz demonstrates a solid business presence in the Czech financial media sector with good content quality and technical implementation. Enhancements in privacy transparency, security headers, and mobile responsiveness would further strengthen its security posture and user 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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

Kurzy.cz holds a strong position as a financial market data and news provider in the Czech Republic, serving a medium-sized audience of investors and financial professionals. Its business model relies primarily on advertising revenue supported by extensive market data and news content. The site integrates multiple third-party analytics and advertising platforms, indicating a mature digital marketing approach. The absence of direct contact information and corporate details suggests a focus on content delivery rather than direct customer engagement. The portal's frequent updates and diverse financial coverage provide competitive advantages in the local market. Strategic partnerships with data providers and financial institutions likely underpin its data accuracy and timeliness.

Security posture

The website maintains a good baseline security posture with HTTPS enabled and asynchronous script loading to reduce attack surface. Cookie consent mechanisms indicate awareness of privacy regulations. However, the lack of security headers such as Content-Security-Policy and absence of explicit security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The missing WHOIS data and lack of registrant transparency slightly reduce trust but do not indicate malicious intent. Overall, the site is secure for typical user interactions but would benefit from enhanced security controls and transparency to meet higher compliance standards.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Enhance mobile responsiveness and accessibility to improve user experience across devices.
  4. Provide clear contact information including security incident response contacts to improve trust and compliance.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.

Technical notes

Notes

The website uses a combination of modern web technologies including jQuery 3.6.0, Google Fonts, and multiple analytics and advertising scripts from Google, Facebook, and Gemius. The site loads scripts asynchronously to optimize performance. The HTML structure is well-formed with proper meta tags for SEO and Open Graph for social sharing. However, no CMS or backend platform was identified. Hosting provider details are not disclosed. Performance is moderate with room for improvement in mobile optimization and accessibility. The site lacks advanced frameworks but is stable and functional for its purpose.
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.
