Bazos.cz is a prominent Czech online classified ads platform offering free listings across a wide range of categories including vehicles, real estate, jobs, electronics, and more. It serves a broad general audience primarily in the Czech Republic and neighboring countries through regional partner sites. The website features a well-organized category structure and supports user interaction via search and ad posting functionalities. Technically, the site uses standard web technologies including HTML5, CSS, JavaScript with AJAX for dynamic suggestions, and integrates Google Analytics for traffic analysis. The site is served over HTTPS, ensuring secure communications, and includes cookie consent mechanisms aligned with GDPR requirements. However, the absence of WHOIS registration data reduces transparency and trustworthiness from a domain registration perspective. Security policies and incident response contacts are not explicitly provided, which could be improved to enhance user trust and compliance. Overall, the site presents a professional and functional e-commerce classified ads service with moderate technical maturity and good privacy 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.

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

      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

Bazos.cz holds a strong market position as a leading classified ads platform in the Czech Republic, with over 1.6 million ads and daily active listings. Its business model revolves around free user-generated listings monetized likely through advertising and possibly premium services. The platform targets a wide demographic including individuals and small businesses seeking to buy or sell goods and services. The presence of regional partner domains in Slovakia, Poland, and Austria indicates a strategic regional expansion or partnership approach. The platform's competitive advantage lies in its simplicity, category breadth, and local market focus. While no direct revenue streams or parent company information is disclosed, the site’s scale suggests a large user base and significant market penetration. The lack of explicit certifications or security frameworks indicates potential areas for business maturity improvement.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and cookie consent implemented, reflecting awareness of privacy regulations such as GDPR. However, the absence of security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and others reduces defense-in-depth. No explicit security policies or incident response contacts are published, which limits transparency and preparedness communication. The use of third-party scripts such as Google Analytics is managed with consent restrictions on ad personalization, which is positive. No vulnerabilities or exposed sensitive data were detected in the HTML content. To improve security posture, the site should implement comprehensive security headers, publish security policies, and establish clear incident response channels.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a dedicated security policy page and provide incident response contact information to improve transparency and user trust.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices.
  5. Verify and update WHOIS domain registration information to improve legitimacy and trust signals.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS, and JavaScript with AJAX for dynamic content suggestions. It integrates Google Tag Manager and Google Analytics for marketing and analytics purposes. The site is served over HTTPS, indicating a secure transport layer. The performance is moderate with basic mobile optimization and accessibility features. SEO is supported by proper meta tags, canonical links, and structured data in JSON-LD format describing the website and organization. No CMS or specific frameworks were detected, suggesting a custom or lightweight platform. Hosting provider details are not disclosed. Opportunities exist to modernize the tech stack by adopting progressive web app features, improving accessibility compliance, and optimizing performance for mobile users.
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.
