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

The website www.lazadov.cz represents Lyžařský areál Zadov, a regional ski and outdoor activity resort located in the Šumava region of the Czech Republic. The business offers a variety of seasonal recreational services including skiing, snowboarding, bike rentals, rope parks, and accommodation. It targets tourists and outdoor sports enthusiasts with a focus on family-friendly activities. The site is professionally designed with good content quality and clear navigation, supporting Czech language primarily. Technically, the site uses common JavaScript libraries such as jQuery and Flexslider, integrates social media widgets, and employs Google Analytics and retargeting scripts. Cookie consent mechanisms are implemented, indicating basic privacy compliance. However, WHOIS data for the domain is unavailable, which raises concerns about domain registration legitimacy. Security posture is moderate with HTTPS implied but lacking explicit security headers and incident response information. Overall, the site is functional and trustworthy for users but would benefit from enhanced security and compliance 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

6 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 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';…

  2. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 3 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

Lyžařský areál Zadov operates in the hospitality and tourism sector, providing outdoor sports and accommodation services. The business model relies on seasonal tourism with offerings tailored to winter skiing and summer biking activities. The company is affiliated with Česká unie sportu z.s., which appears as the legal entity. The website demonstrates a solid partnership ecosystem with regional tourism and sports organizations. Revenue streams likely include ticket sales, equipment rentals, accommodation bookings, and event hosting. The presence of social media channels and interactive content suggests active marketing efforts. Growth indicators include event calendars and seasonal updates. The business maintains a regional market position with a focus on Šumava visitors.

Security posture

The website exhibits a moderate security maturity level. HTTPS is used, ensuring encrypted communication. Cookie consent is implemented with opt-in/out options, supporting GDPR compliance. However, no security headers such as Content Security Policy or HSTS were detected, which could improve protection against common web attacks. No forms or input fields were found on the main page, reducing attack surface. The absence of incident response contacts and vulnerability disclosure policies indicates gaps in security governance. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is adequate for a public informational site but could be strengthened with additional controls and transparency.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against web-based attacks.
  2. Publish explicit terms of service and incident response contact information to improve compliance and user trust.
  3. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and remediation.

Technical notes

Notes

The website uses a traditional web stack with jQuery, jQuery UI, Flexslider, and Fancybox for UI components and interactivity. Google Fonts and Font Awesome provide typography and icons. Analytics and marketing tools include Google Analytics, Google Tag Manager, and Seznam retargeting scripts. The site integrates third-party widgets such as ElfSight Instagram feed. The HTML structure is well-formed with meta tags for SEO and responsive design. Performance is moderate with some dynamic content like sliders and carousels. Mobile optimization is good, supported by responsive CSS and viewport settings. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not disclosed. Overall, the technical implementation is solid but could benefit from modernization and enhanced security practices.
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.
