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

Lyžařský areál Zadov is a regional ski and outdoor recreational area located in the Šumava region of the Czech Republic. The website provides information about ski lifts, bike rentals, accommodation options, webcams, and upcoming events. The business operates seasonally with a focus on winter sports and summer outdoor activities, targeting tourists and sports enthusiasts. The site is professionally designed with consistent branding and offers multilingual support (Czech and German). The parent organization is Česká unie sportu z.s., indicating a formal sports union affiliation. Technically, the website uses common JavaScript libraries such as jQuery, Flexslider, and Fancybox, along with Google Analytics and a cookie consent mechanism. The site is mobile-optimized and includes social media integration via Facebook, Twitter, and Instagram. However, no CMS or hosting provider details are explicitly identified. Performance is moderate with room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS and implements cookie consent, but lacks advanced security headers and a public vulnerability disclosure policy. WHOIS data is unavailable, which reduces transparency and trustworthiness. The expired certification shown on the site should be updated or removed to avoid confusion. Overall, the security posture is adequate but could be enhanced with additional best practices. The overall risk assessment is moderate. The site appears legitimate and serves a clear business purpose, but the lack of WHOIS transparency and some security best practices suggest areas for improvement. Strategic recommendations include implementing security headers, publishing a security.txt file, updating certifications, and enhancing privacy and accessibility compliance.

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

5 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

The ski area operates in the hospitality and transportation sectors, providing ski lifts, bike rentals, and accommodation referrals. It targets tourists visiting the Šumava region year-round, with a focus on winter sports and summer outdoor activities. The business model relies on direct service provision and partnerships with local accommodation and equipment providers. The presence of partner logos and social media channels indicates active marketing and community engagement. The expired certification suggests prior quality assurance efforts. The domain's lack of WHOIS data is a concern but does not negate the visible business operations. Growth potential exists through expanded digital presence and improved compliance. Partnerships with local businesses and sports unions strengthen market position. The website content is relevant and updated with event information, supporting customer engagement. The business is small-sized with a regional focus, and its digital maturity is moderate, leveraging standard web technologies and analytics.

Security posture

The website uses HTTPS, which is mandatory for secure communications. Cookie consent is implemented, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No security.txt or vulnerability disclosure policy is found, limiting transparency for security researchers. The WHOIS data is missing, which may indicate privacy protection or lack of registration, impacting trust. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses reputable third-party scripts and analytics services. The expired certification shown on the site should be addressed to maintain trust. Overall, the security posture is adequate but can be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Update or remove expired certifications to avoid misleading visitors.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Expand privacy policy details and ensure GDPR compliance with clear data retention policies.

Technical notes

Notes

The website is built using classic web technologies including jQuery, jQuery UI, Flexslider, and Fancybox for UI components and interactivity. Google Analytics and Google Tag Manager are used for traffic analysis and marketing. CookieScript manages cookie consent. The site loads fonts from Google Fonts and uses Elfsight for Instagram feed integration. The HTML is well-structured with meta tags for SEO and responsive design via media queries. Performance is moderate with some JavaScript and CSS optimizations possible. No modern CMS or frameworks like React or Angular are detected. Hosting provider details are not disclosed. The site is mobile-optimized and supports multiple languages. Technical debt appears low but modernization opportunities exist to improve performance 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.
