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

JumpPark is a trampoline park business operating multiple branches in the Czech Republic, primarily in Prague and Brno. The company offers recreational trampoline activities, teambuilding events, and online reservation services. The website is professionally designed with a clear focus on family-friendly entertainment and fitness. The technical infrastructure leverages modern frontend technologies including Bootstrap, jQuery, and Google Tag Manager, with a cookie consent mechanism ensuring GDPR compliance. Security posture is moderate with HTTPS implied but lacking explicit security headers and incident response contacts. The absence of WHOIS data reduces transparency and trustworthiness, though the website content and domain usage appear legitimate for a local business. Overall, the site provides a good user experience with room for improvement in security and business credibility disclosures.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 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

JumpPark positions itself as a local entertainment provider specializing in trampoline parks with four physical locations. Its business model centers on physical venue services complemented by an online booking system. The company targets families, youth, and corporate groups seeking teambuilding activities. The website branding is consistent and professional, supporting trust signals such as multiple branch presence and GDPR compliance. However, limited contact information and missing WHOIS data suggest opportunities to enhance transparency and customer confidence. The company appears to operate independently without visible parent or subsidiary affiliations.

Security posture

The website demonstrates basic security hygiene with HTTPS usage and a cookie consent banner aligned with GDPR requirements. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates potential vulnerabilities to common web attacks. No incident response or security contact information is provided, limiting the ability to report or respond to security issues. Third-party scripts like Google Tag Manager and CookieScript are used, which require regular auditing to prevent supply chain risks. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, publishing security policies, and establishing incident response channels.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a comprehensive privacy and security policy page detailing data protection practices and user rights.
  3. Add explicit contact information for security incidents such as security@ or abuse@ email addresses.
  4. Verify and publish WHOIS domain registration details to improve transparency and trustworthiness.
  5. Regularly audit third-party scripts and dependencies to minimize supply chain risks.

Technical notes

Notes

The website uses a modern and widely adopted frontend technology stack including Bootstrap 4, jQuery, Popper.js, and FontAwesome for UI components and icons. Google Tag Manager is integrated for analytics and marketing tracking, alongside CookieScript for cookie consent management. The site is mobile responsive and provides a good user experience with clear navigation and content structure. Performance is moderate, likely influenced by external resources loading from CDNs. No CMS or hosting provider information is explicitly detected. The site lacks advanced accessibility features and SEO optimizations could be enhanced. Technical debt appears low but security improvements are recommended.
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.
