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 serves investors, traders, and the general public interested in financial markets. The site offers a broad range of market data and news articles with frequent updates, positioning itself as a key player in the Czech financial media space. Technically, the website employs modern JavaScript libraries such as jQuery and integrates multiple third-party analytics and advertising services including Google Tag Manager, Gemius, and Facebook Pixel. The site uses HTTPS and has a cookie consent mechanism, indicating some level of privacy compliance. However, the absence of a visible privacy policy and terms of service, as well as missing WHOIS data, slightly detracts from its transparency and trustworthiness. Security headers are partially implemented but could be improved to enhance protection against common web vulnerabilities. Overall, Kurzy.cz presents a professional and content-rich platform with moderate technical maturity and a good security posture, but it would benefit from enhanced privacy disclosures and domain 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

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 operates in the finance and media sectors, targeting Czech-speaking investors and financial market participants. Its business model relies primarily on advertising revenue, supported by extensive market data and news content. The portal covers domestic and international stock markets, currency exchange, commodities, and macroeconomic indicators. It maintains partnerships with related news and financial data providers, as evidenced by linked domains such as zpravy.kurzy.cz and meteobox.cz. The site demonstrates consistent branding and content quality, with a medium-sized audience base. The lack of explicit company contact details and WHOIS transparency suggests a focus on content delivery rather than direct customer engagement. Growth opportunities may lie in expanding privacy compliance and enhancing direct user interaction channels.

Security posture

The website enforces HTTPS, which is fundamental for secure communications. It integrates multiple third-party scripts for analytics and advertising, which increases the attack surface and requires vigilant management. Security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, representing potential vulnerabilities to XSS, clickjacking, and MIME sniffing attacks. The cookie consent mechanism indicates awareness of privacy regulations, but the absence of a detailed privacy policy and terms of service is a compliance gap. No incident response or security contact information is found, which could hinder timely vulnerability reporting and mitigation. Overall, the security posture is moderate but would benefit from implementing recommended HTTP headers, publishing clear privacy and security policies, and establishing incident response channels.

Recommendations

  1. Implement a comprehensive Content-Security-Policy header to mitigate XSS risks.
  2. Add X-Frame-Options and X-Content-Type-Options headers to enhance protection against clickjacking and MIME sniffing.
  3. Publish a detailed privacy policy and terms of service accessible from the homepage.
  4. Provide clear contact information for security incidents and data protection inquiries.
  5. Investigate and resolve the absence of WHOIS data to improve domain transparency and trust.

Technical notes

Notes

The website uses a combination of modern web technologies including jQuery 3.6.0, Google Fonts, and multiple third-party analytics and advertising scripts such as Gemius and Google Tag Manager. The HTML structure is well-formed with proper meta tags for SEO and Open Graph for social media sharing. Performance is moderate with asynchronous loading of scripts to improve page load times. Mobile optimization is basic, with a fixed viewport width of 990px, which may limit responsiveness on smaller devices. Accessibility features are minimal but present. The site lacks a detected CMS, suggesting a custom or proprietary platform. Hosting provider details are not discernible from the content. Technical risks include reliance on multiple third-party scripts and missing security headers, which could expose the site to common web vulnerabilities.
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.
