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

Kurzy.cz is a well-established Czech financial information portal providing comprehensive data on currency exchange rates, stock markets (both domestic and international), commodities, economic indicators, and financial news. The site targets investors, traders, and the general public interested in financial markets and economic news. It offers a variety of financial tools including calculators and market charts, positioning itself as a key resource in the Czech financial media landscape. Technically, the website employs common web technologies such as jQuery, Google Tag Manager, and multiple advertising and analytics services including Gemius and Facebook Pixel. The site is served over HTTPS with a good SSL configuration but lacks some advanced security headers. Privacy compliance is basic with a cookie consent mechanism but no clearly accessible privacy or terms of service pages. No WHOIS data is available from the CZ NIC registry, which is typical for Czech domains but reduces transparency. Overall, the site is professional, content-rich, and trustworthy, though it could improve in privacy disclosures and security hardening.

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

Kurzy.cz operates in the finance and media sectors, providing real-time and historical financial data, news, and analysis. Its business model revolves around advertising revenue and possibly premium services or partnerships. The portal integrates with several partner domains offering complementary services such as business registries, travel, automotive, weather, real estate, and education, enhancing its ecosystem. The site’s extensive content and tools indicate a large user base and significant market presence in the Czech Republic. The lack of explicit company registration or contact details on the site suggests a focus on content delivery rather than direct customer service. The site’s longevity and comprehensive offerings position it as a competitive player in the Czech financial information market.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and no visible critical vulnerabilities in the HTML content. However, the absence of explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement. The use of multiple third-party scripts and trackers increases the attack surface and privacy risks. No incident response or security policy information is publicly available, which could hinder transparency and trust. The cookie consent mechanism suggests some awareness of privacy regulations, but the lack of a detailed privacy policy and terms of service is a compliance gap. Overall, the site is secure enough for general use but should enhance security headers and transparency to improve its security maturity.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish clear and accessible privacy policy and terms of service pages to improve GDPR compliance and user trust.
  3. Enhance mobile optimization to provide a better user experience on smartphones and tablets.
  4. Regularly audit and minimize third-party scripts to reduce privacy risks and improve performance.
  5. Establish and publish an incident response policy and security contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a traditional web technology stack with jQuery 3.6.0 and integrates multiple third-party analytics and advertising services such as Gemius, Google Tag Manager, Google Ads, and Facebook Pixel. The site is served over HTTPS with a good SSL configuration, ensuring encrypted communication. Performance appears moderate with some room for improvement in mobile responsiveness and accessibility. SEO is supported by proper meta tags and Open Graph tags, enhancing social media sharing and search engine visibility. The site does not appear to use a known CMS or modern JavaScript frameworks, indicating a possibly custom or legacy platform. Technical debt may exist due to reliance on older libraries and multiple external scripts, which could impact maintainability and security.
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.
