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

Bowling Brno is a medium-sized hospitality and leisure business located in Brno, Czech Republic, offering a variety of sports and entertainment services including bowling, adventure golf, beach volleyball, a golf simulator, and restaurant facilities. The website is professionally designed with good content quality and clear navigation, targeting families, sports enthusiasts, and corporate clients. The business maintains an active social media presence and community engagement through youth sports programs and tournaments. Technically, the website uses modern JavaScript libraries and frameworks such as Foundation, jQuery, and LightGallery, with Google Analytics and Facebook SDK for tracking. However, there is no evidence of a CMS or hosting provider information. Security posture is moderate with HTTPS implied but lacking explicit security headers and published security policies. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism detected. WHOIS data is missing, which reduces domain trustworthiness and should be investigated further. Overall, the website is functional, trustworthy, and suitable for its business purpose but could improve in security and privacy 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

12 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

  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 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';…

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 company operates in the hospitality sector with a focus on sports and leisure activities. It leverages multiple revenue streams including bowling lane rentals, restaurant services, sports tournaments, and youth programs. The market position is local and community-oriented with partnerships to related businesses and active engagement in regional sports events. The business model is service-based with a strong emphasis on customer experience and event hosting. Growth indicators include expansion into adventure golf and youth sports clubs. The partnership ecosystem includes local businesses and sports organizations, enhancing credibility and reach. Strategic observations suggest opportunities to enhance digital maturity and security posture to support sustainable growth.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and no visible sensitive data exposure. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No vulnerability disclosures or incident response information are published, indicating limited transparency in security practices. GDPR compliance is partially addressed with a privacy policy but lacks cookie consent mechanisms. The use of third-party analytics and social media scripts introduces potential privacy risks. Overall, the security culture appears basic and would benefit from formal policies, security headers, and incident response readiness to mitigate risks and enhance trust.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen site security.
  2. Add a cookie consent banner to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a security policy and incident response plan to improve transparency and preparedness.
  4. Conduct regular audits of third-party scripts and libraries to identify and mitigate vulnerabilities.
  5. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.

Technical notes

Notes

The website uses a modern front-end stack with Foundation CSS framework, jQuery, and various UI enhancement libraries such as LightGallery and Vegas for slideshows. Analytics are implemented via Google Analytics and Facebook SDK. The site is mobile responsive with good SEO meta tags and Open Graph data. However, no CMS or hosting provider information is evident, and performance is moderate with potential for optimization. Accessibility features are basic but present. Technical debt appears low, but security improvements and privacy compliance enhancements are recommended to reduce risks and improve user trust.
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.
