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

Alza.cz is a well-established e-commerce retailer founded in 2004, primarily serving the Czech Republic and neighboring countries with a focus on consumer electronics. The website is currently protected by Cloudflare's Web Application Firewall (WAF) and Turnstile CAPTCHA, which blocks direct access and limits content visibility. This security measure indicates a strong posture against automated threats but restricts full content and compliance analysis. The technical infrastructure leverages Cloudflare for hosting and security, but lacks visible SEO and accessibility features in the accessible content. No privacy, cookie, or terms of service policies are detectable, which is a compliance gap. Contact information is limited to email addresses embedded in the security challenge text, with no phone numbers or physical addresses visible. Overall, the site shows a mature domain age and consistent WHOIS data, supporting legitimacy, but the blocked content and missing compliance documentation reduce the ability to fully assess the website's security and privacy posture.

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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Alza.cz operates as a leading online retailer in the Czech Republic, focusing on electronics and technology products. The business model is e-commerce with localized country-specific domains and customer support emails. The company benefits from a long domain history and strong brand recognition in its market. The use of Cloudflare indicates investment in security and performance. However, the lack of visible privacy and cookie policies, as well as absence of phone or physical contact details, suggests areas for improvement in customer trust and regulatory compliance. The website's current WAF challenge limits user access and may impact user experience and SEO performance.

Security posture

The website employs Cloudflare's WAF and Turnstile CAPTCHA, providing robust protection against bots and automated attacks. HTTPS is enforced, ensuring encrypted communications. However, no explicit security headers were detected in the provided data, and no incident response or vulnerability disclosure information is available. The absence of privacy and cookie policies is a compliance concern under GDPR. The security posture is strong in terms of perimeter defense but lacks transparency and user-facing security documentation. The blocked content status limits the ability to detect vulnerabilities or security best practices in forms or scripts.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add terms of service and security policy pages accessible to users.
  3. Implement and expose security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide visible contact information including phone numbers and physical addresses to enhance trust.
  5. Consider user experience impact of WAF challenge and optimize CAPTCHA flow for legitimate users.
Site observations

Technical notes

Notes

The website uses Cloudflare for hosting, security, and performance optimization, including Cloudflare Insights for analytics and Turnstile CAPTCHA for bot mitigation. The HTML content is minimal due to the security challenge page, lacking meta tags, structured data, and SEO optimizations. The site uses SVG logos and JavaScript for dynamic content rendering. Mobile optimization and accessibility are basic but cannot be fully assessed due to blocked content. The domain is mature and consistent with the business profile. Technical debt or modernization needs cannot be fully evaluated given the limited accessible content.
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.
