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

BONVER WIN a.s. operates as the largest Video Lottery Terminal (VLT) and casino operator in the Czech Republic, offering both physical casino locations and an online casino platform. The company targets adult customers interested in gambling entertainment, providing a network of over 60 gaming venues nationwide and an online presence through bonvercasino.cz. The website content is professionally presented with clear navigation and age verification to restrict underage access. Technically, the site uses modern JavaScript libraries such as jQuery and Slick Carousel, along with Google Tag Manager and Google Analytics for tracking and marketing purposes. However, the absence of WHOIS data and registrant information limits domain trust verification. Security posture is moderate with HTTPS implied but lacks visible security headers and published privacy or terms documents. Overall, the site is functional and compliant with basic cookie consent and age verification requirements but could improve transparency and security practices.

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

7 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

BONVER WIN a.s. holds a strong market position as the leading VLT operator in the Czech Republic, leveraging a broad physical presence and an expanding online casino platform. Their business model focuses on gambling services, loyalty programs, and jackpot offerings, targeting adult gamblers. The company benefits from brand consistency and a clear focus on the hospitality sector. Growth indicators include recent news updates and expansion of gaming locations. The partnership with bonvercasino.cz strengthens their digital footprint. However, the lack of publicly available WHOIS data and contact information may pose challenges for trust and regulatory compliance verification.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and cookie consent mechanisms in place. The presence of an age verification popup aligns with regulatory requirements for gambling sites. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No explicit privacy policy or incident response contacts are published, which may expose compliance gaps under GDPR and NIS2 frameworks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from enhanced security policies, transparency on data protection, and incident response readiness to improve overall security posture.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the main navigation or footer.
  2. Implement and configure security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Provide clear contact information for security incidents and designate a Data Protection Officer if applicable.
  4. Conduct regular security audits of third-party scripts and dependencies to mitigate vulnerabilities.
  5. Enhance accessibility features to meet compliance standards and improve user experience.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS, and JavaScript with jQuery and Slick Carousel libraries for UI components. Google Tag Manager and Google Analytics are integrated for marketing and analytics purposes. The site appears mobile-optimized with responsive design elements and a clear navigation structure. Performance is moderate with no obvious blocking scripts. No CMS or hosting provider information is directly detectable from the HTML content. The absence of advanced frameworks or CMS suggests a custom or lightweight platform. Technical risks include missing security headers and lack of visible privacy and compliance documentation.
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.
