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

The website www.kudrna.cz represents Kudrna s.r.o., a Czech travel agency specializing in active and outdoor vacations including hiking, cycling, water sports, skiing, and expeditions. Founded in 1979, the company offers a wide range of travel packages primarily targeting Czech and Slovak customers interested in adventure and cultural travel experiences. The site features detailed trip listings, articles, and event information, supported by a modern and user-friendly design with good SEO and mobile optimization. Technically, the site uses ASP.NET WebForms with various JavaScript libraries such as jQuery, Fancybox, and noUiSlider, and integrates Google Tag Manager for analytics. However, the absence of WHOIS data and missing privacy and cookie policies indicate areas for improvement in transparency and compliance. Security posture is moderate with HTTPS implied but lacking visible security headers. Overall, the site is professional and trustworthy but would benefit from enhanced privacy compliance 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

8 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

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

Kudrna s.r.o. occupies a niche market in the Czech Republic for active outdoor travel, leveraging a long-standing reputation since 1979. Their business model focuses on curated travel experiences with a loyal customer base, offering diverse trip types from hiking to expeditions. The company emphasizes quality and customer trust through insurance coverage and experienced guides. The website supports business growth with detailed trip search and booking capabilities, though lacks explicit privacy and cookie policies which are critical for GDPR compliance. The company targets primarily Czech and Slovak markets with localized language support. No parent or subsidiary companies were identified. The partnership ecosystem is not explicitly detailed on the site.

Security posture

The website enforces HTTPS and uses secure cookies, indicating basic security hygiene. However, no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected in the provided data, which could expose the site to certain web-based attacks. The absence of a security.txt file or vulnerability disclosure policy limits transparency for security researchers. No exposed sensitive data or vulnerable libraries were identified in the HTML content. Forms are protected with validation scripts. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, formal incident response contacts, and privacy compliance mechanisms.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with explicit user consent mechanisms to ensure GDPR compliance.
  2. Add standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Verify and publish WHOIS domain registration data to improve transparency and trustworthiness.
  4. Establish a security.txt file and a clear vulnerability disclosure policy to facilitate responsible security reporting.
  5. Enhance accessibility features and conduct regular security audits to maintain a robust security posture.

Technical notes

Notes

The website is built on ASP.NET WebForms with a custom CMS (MagicWare) and uses a variety of modern frontend libraries including jQuery, Fancybox, noUiSlider, and Air Datepicker. It integrates Google Tag Manager for analytics and uses Google Fonts and Adobe Typekit for typography. The site is mobile responsive with good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with lazy loading images and asynchronous scripts. However, the site lacks visible security headers and formal privacy and cookie compliance mechanisms. The technical stack is mature but could benefit from modernization and enhanced security controls.
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.
