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

Alza.cz is a leading e-commerce retailer primarily serving the Czech Republic and neighboring countries, specializing in consumer electronics and related products. The company has a long-standing market presence since 2004 and operates a large-scale online retail platform. The website is currently protected by Cloudflare's security mechanisms, including a Turnstile CAPTCHA challenge, which restricts direct content access and limits full analysis. The technical infrastructure leverages Cloudflare for security and performance, indicating a mature approach to protecting the site from bots and attacks. However, the visible content is minimal due to the security challenge, and no explicit privacy or cookie policies are presented on the challenge page. Security posture is strong in terms of HTTPS and WAF usage, but lacks visible security headers and incident response information. Overall, the site demonstrates a solid business foundation but requires improved transparency and accessibility for compliance and user trust.

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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 holds a dominant position in the Czech e-commerce market with a focus on electronics retail. Its business model revolves around direct online sales supported by localized customer service emails for multiple countries. The company benefits from a mature domain age and consistent registration data. While the website is professionally branded and uses modern security infrastructure, the current Cloudflare challenge page limits visibility into customer engagement features such as contact forms or phone support. The lack of visible privacy and cookie policies suggests room for improvement in regulatory compliance and customer trust. The company likely operates a broad partnership ecosystem given its multi-country email support, but no explicit partner or subsidiary domains were identified in the analyzed content.

Security posture

The website employs HTTPS and Cloudflare's security services, including a Web Application Firewall and Turnstile CAPTCHA, which effectively mitigate automated threats and bot traffic. However, the absence of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security hardening. No vulnerabilities or exposed sensitive data were detected in the accessible content. The lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms indicates gaps in transparency and readiness for security incidents. The security score is moderate due to strong infrastructure but limited visible security governance documentation.

Recommendations

  1. Publish clear and accessible privacy and cookie policies on the main website.
  2. Implement and expose standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection.
  3. Provide visible contact information including phone numbers and incident response emails for security issues.
  4. Establish and publicize a vulnerability disclosure program or security.txt file.
  5. Improve mobile optimization and accessibility features to enhance user experience and compliance.

Technical notes

Notes

The website uses Cloudflare for hosting, security, and performance optimization, including the Turnstile CAPTCHA for bot mitigation. The HTML content is well-structured but currently serves a security challenge page rather than full site content. The tech stack includes JavaScript and SVG graphics, but no CMS or backend platform was identified from the provided data. Performance is moderate given Cloudflare's CDN usage, but mobile optimization and accessibility are basic. SEO metadata and structured data are absent on the challenge page, limiting search engine visibility. The site would benefit from improved meta tags, structured data, and enhanced accessibility compliance.
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.
