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

Sbazar.cz is a large Czech online marketplace and classified ads platform operated by Seznam.cz, a leading Czech internet company. The platform offers free posting and browsing of millions of listings across diverse categories such as electronics, vehicles, clothing, antiques, real estate, and services. It targets consumers in the Czech Republic seeking to buy and sell new and used goods efficiently. The business model is based on providing a free-to-use classifieds service with monetization likely through advertising and premium features. Technically, the website employs modern web technologies including the Astro framework and Preact for frontend rendering, along with integrations for analytics and user tracking via Hotjar and Gemius. The site is mobile optimized and demonstrates good SEO practices with structured data and meta tags. Performance is moderate, with room for improvement in accessibility features. From a security perspective, the site enforces HTTPS and uses modern JavaScript frameworks, but lacks explicit security headers and visible privacy or cookie policies in the provided content. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data reduces domain trust, but the association with Seznam.cz supports legitimacy. No WAF or blocking mechanisms were detected, indicating full content accessibility. Overall, Sbazar.cz presents as a professional and trustworthy e-commerce platform with a strong market position in the Czech Republic. However, improvements in transparency around privacy, security policies, and domain registration details would enhance trust and 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.

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 Policy found

      GDPR requires clear information about cookie usage

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Sbazar.cz holds a strong market position as a major Czech classifieds platform under the Seznam.cz umbrella. Its competitive advantage lies in its extensive category coverage and free ad posting, attracting a large user base. The business model focuses on volume-driven advertising revenue and possibly premium listing services. Target customers are Czech consumers and small businesses. The platform benefits from integration with Seznam.cz's ecosystem, including login and advertising services. Growth indicators include nearly 2 million active listings and continuous technical modernization. Strategic partnerships with Seznam.cz and use of advanced analytics tools support data-driven decision making and marketing effectiveness.

Security posture

The security posture of Sbazar.cz is moderate to good. HTTPS is enforced, ensuring encrypted communications. The use of modern frameworks reduces common vulnerabilities. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No privacy or cookie policies were found, which is a compliance concern under GDPR. Incident response and vulnerability disclosure mechanisms are not visible, limiting transparency. No exposed credentials or sensitive data were detected. Overall, the platform demonstrates basic security hygiene but should enhance policy transparency and header configurations to improve security maturity and regulatory compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen security posture.
  3. Provide clear contact information and dedicated security incident response contacts.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Improve accessibility features to meet recognized standards and enhance user experience.

Technical notes

Notes

Sbazar.cz uses a modern technical stack centered on the Astro framework and Preact for efficient client-side rendering. The site integrates multiple third-party analytics and tracking tools such as Hotjar and Gemius, enabling detailed user behavior analysis. Performance is moderate with good mobile optimization. SEO is well addressed through meta tags and structured JSON-LD data. The absence of a known CMS suggests a custom or proprietary platform. Hosting details are not explicit but likely managed by Seznam.cz infrastructure. Technical risks include reliance on multiple external domains for scripts and analytics, which could impact privacy and performance. Opportunities exist to improve accessibility and security header implementation.
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.
