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

Kurzy Sprint s.r.o. is a Czech Republic-based education provider specializing in practical courses for real estate agents and accounting professionals. The company offers both online and live courses designed to equip learners with immediately applicable skills. Their market position is niche-focused, targeting professionals seeking practical knowledge rather than purely theoretical education. The website is well-structured, professionally designed, and optimized for SEO and mobile devices, reflecting a mature digital presence. Technically, the website is built on WordPress with WooCommerce for e-commerce functionality, enhanced by plugins such as Yoast SEO and Complianz GDPR for privacy compliance. The site uses modern web technologies including jQuery and Google Fonts, and implements HTTPS with good SSL configuration. Performance is moderate, with caching and lazy loading techniques employed. Privacy compliance is strong, featuring a comprehensive cookie consent mechanism and clear privacy policies. From a security perspective, the site enforces HTTPS and anonymizes IP addresses in analytics, but lacks some recommended security headers and explicit security or incident response policies. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust verification, though the professional presentation and contact information support legitimacy. Overall, Kurzy Sprint demonstrates a solid business and technical foundation with good privacy compliance. Strategic improvements in security headers, incident response transparency, and domain registration verification would enhance trust and security posture further.

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

9 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

  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 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

Kurzy Sprint operates in the education sector with a focus on real estate and accounting courses, serving a specialized professional audience in the Czech Republic. Their business model combines online and live training, leveraging digital platforms for course delivery and marketing. The company maintains partnerships with related course providers and web design firms, indicating a collaborative ecosystem. Revenue streams likely include course fees and exam preparation services. The website content and references suggest a small-sized company with a stable market presence since 2015. The clear contact information and customer references enhance credibility and support customer acquisition.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and privacy-conscious analytics configuration. The presence of a GDPR-compliant cookie consent banner and detailed privacy policy indicates good data protection awareness. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No incident response or security policy documentation was found, which limits transparency and preparedness perception. The absence of WHOIS data reduces domain trust verification. Overall, the security posture is adequate for the business type but could be improved with additional controls and documentation.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  3. Regularly audit and update WordPress plugins and themes to minimize vulnerability exposure.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  5. Enhance website accessibility features to broaden user inclusivity and compliance.

Technical notes

Notes

The website is built on a WordPress CMS platform with WooCommerce for e-commerce capabilities. It uses common web technologies such as jQuery, Google Fonts, and several WordPress plugins including Yoast SEO for search engine optimization and Complianz GDPR for privacy compliance. Performance optimizations include caching (W3 Total Cache) and lazy loading of images. The site is mobile responsive and has a clear navigation structure. However, there is no explicit hosting provider information detected. The technical implementation is modern but could benefit from enhanced security headers and accessibility improvements.
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.
