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

Aquapark Děčín is a regional aquatic and wellness center located in the Czech Republic, offering a broad range of water-based recreational and sports activities including indoor aquapark attractions, summer swimming pools, wellness services such as saunas and massages, swimming schools, and sports facility rentals. The website targets families, sports enthusiasts, and local visitors seeking aquatic entertainment and wellness. The business operates as a public organization, indicated by its legal name, and maintains a consistent brand presence with active social media channels. Technically, the website employs common JavaScript libraries and tracking tools such as jQuery, Google Analytics, Facebook Pixel, and Cookiebot for cookie consent management. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS enforced and cookie consent implemented; however, the absence of security headers and explicit security policies suggests room for improvement. The lack of WHOIS data reduces domain trustworthiness, though the website content and social presence support legitimacy. Overall, the site is functional, professional, and compliant with basic privacy regulations.

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

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

Aquapark Děčín holds a solid position as a local aquatic and wellness provider, focusing on family-friendly and sports-related aquatic services. Its business model revolves around public recreational services with ancillary revenue from wellness and sports facility rentals. The presence of a partner hotel domain indicates a complementary hospitality ecosystem. The website's content and structure suggest a medium-sized operation with a focus on community engagement and service diversity. Growth potential exists through enhanced digital presence and expanded wellness offerings. The absence of detailed business registration data online limits deeper competitive analysis. The company demonstrates awareness of GDPR compliance and user privacy through cookie consent mechanisms.

Security posture

The website enforces HTTPS and uses cookie consent tools, reflecting a baseline security and privacy posture. However, the lack of detected security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates potential vulnerabilities to common web attacks. No explicit security or incident response policies are published, and no contact channels for security incidents are provided. The use of standard third-party analytics and tracking scripts introduces moderate user tracking but appears compliant with privacy norms. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security maturity is moderate but could benefit from enhanced header policies, published security documentation, and improved contact transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response plan accessible from the website to improve transparency and preparedness.
  3. Add explicit and verified contact information including emails and phone numbers for general and security-related inquiries.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize unnecessary user tracking.

Technical notes

Notes

The website uses a traditional web stack with jQuery and jQuery UI for UI components, Colorbox for modal dialogs, and integrates Google Analytics and Facebook Pixel for analytics and marketing. Cookiebot manages cookie consent, indicating GDPR compliance efforts. The site is served over HTTPS with a valid SSL certificate, ensuring encrypted communication. Performance is moderate with room for optimization, particularly in loading times and mobile responsiveness. No modern CMS or frameworks were explicitly detected, suggesting a custom or legacy platform. The site structure is clear with well-organized navigation menus and content sections. Technical risks include missing security headers and potential outdated libraries, which should be addressed to reduce attack surface and improve security posture.
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.
