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

Bzuco is a Czech-based technology company specializing in modern ticketing and event management solutions. Their platform enables event organizers to sell tickets directly, manage entry control via mobile apps, integrate e-shops, and implement cashless payment systems. The company positions itself as a cost-saving alternative to traditional ticketing providers, emphasizing data ownership and reduced commission fees. The website reflects a professional and consistent brand image with clear contact channels and client trust indicators. Technically, the site uses modern web technologies including Google Analytics, Typekit fonts, and AJAX powered by the Nette PHP framework. The site is mobile-optimized and provides a cookie consent mechanism aligned with GDPR requirements. Security posture is adequate with HTTPS enforced and form validation, but lacks visible security headers and dedicated security policies. WHOIS data is unavailable, which reduces transparency and trustworthiness, but the website content and contact information suggest a legitimate business. Overall, the site scores well on content quality, business credibility, and privacy compliance, with room for improvement in security best practices and WHOIS transparency.

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

6 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319

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

Bzuco operates in the technology sector, targeting event organizers and venues in the Czech Republic. Their business model is B2B SaaS and service provision, focusing on ticket sales, entry control, and cashless payments. The company demonstrates market traction with over 500 organizers trusting their platform and significant annual savings for clients. Their ecosystem includes integrations for e-shops and ticket vending machines, enhancing their competitive advantage. The website showcases client logos and savings statistics, reinforcing credibility. The absence of WHOIS data is a notable gap but does not currently undermine operational legitimacy. The company maintains active social media presence on Facebook and Instagram, supporting marketing and customer engagement. Growth indicators include blog updates and a contact form encouraging new client inquiries.

Security posture

The website enforces HTTPS and includes a cookie consent banner with opt-in/out options, indicating awareness of privacy regulations. Form inputs have validation and anti-spam measures. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended to mitigate common web attacks. There is no visible security policy or incident response information, nor a vulnerability disclosure or security.txt file. The lack of WHOIS data reduces transparency and could be a concern for trust. Overall, the security posture is moderate, with good privacy compliance but room for improvement in technical security controls and transparency.

Recommendations

  1. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web vulnerabilities.
  2. Publish explicit privacy and security policy pages detailing data protection practices, incident response, and compliance measures.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Improve accessibility features to meet recognized standards and enhance user experience for all visitors.
  5. Investigate and resolve the missing WHOIS data issue to improve domain transparency and trustworthiness.

The site is mobile responsive with good navigation clarity and professional design. Performance is moderate with no obvious issues. SEO is basic with meta tags and Open Graph tags present but no structured JSON-LD data found. Hosting provider and CMS are not explicitly identified. The site uses custom CSS and JavaScript files with timestamp query parameters for cache busting. No critical technical debt or vulnerabilities were detected in the provided content. Opportunities exist to enhance security headers and improve SEO with structured data.
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.
