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

KlikBazar.cz is a Czech online classifieds marketplace offering free advertising and sales of new and used items without requiring user registration. The platform targets a general audience in the Czech Republic and provides a wide range of product categories including automotive, electronics, home goods, and more. The website is built using modern web technologies such as SvelteKit and integrates Google Adsense for monetization and Senoweb Analytics for user tracking. The site demonstrates good design quality, clear navigation, and mobile optimization, making it accessible and user-friendly. From a technical perspective, the website employs HTTPS ensuring secure communication, and uses contemporary JavaScript frameworks that support performance and responsiveness. However, the absence of explicit privacy and cookie policies, as well as lack of visible contact information, indicates gaps in privacy compliance and business transparency. The WHOIS data for the domain is unavailable, which raises concerns about domain registration legitimacy and trustworthiness. Security posture is moderate with HTTPS enabled and no obvious vulnerabilities detected in the HTML content. The site lacks security headers and formal incident response or vulnerability disclosure mechanisms, which are recommended for enhanced security. Overall, while the platform serves its business purpose effectively, improvements in privacy compliance, domain registration transparency, and security best practices are advised to strengthen trust and regulatory adherence. The risk assessment suggests moderate risk primarily due to missing WHOIS data and privacy compliance gaps. Strategic recommendations include implementing comprehensive privacy and cookie policies, publishing clear contact and incident response information, and enhancing security headers and vulnerability disclosure practices.

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

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 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 Strict-Transport-Security header

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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

KlikBazar.cz operates as a free online classifieds platform in the Czech Republic, targeting general consumers looking to buy and sell a variety of goods. Its business model relies on advertising revenue, primarily through Google Adsense. The platform's competitive advantage lies in its broad category coverage and no-registration-required approach, appealing to casual users. The absence of detailed company information and WHOIS data limits insights into corporate structure and growth indicators. The site appears to be a medium-sized local player in the retail classifieds market, with potential for expansion through improved transparency and compliance. Partnerships or subsidiaries are not evident from the data provided.

Security posture

The website maintains a basic to moderate security posture with HTTPS enforced, ensuring encrypted data transmission. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of formal security policies, incident response contacts, and vulnerability disclosure mechanisms indicates limited preparedness for security incidents. Compliance with GDPR and other privacy regulations is weak due to missing privacy and cookie policies. Enhancing these areas would significantly improve the site's security maturity and reduce potential risks.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  2. Publish explicit contact information including support and incident response channels to enhance business credibility and security readiness.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  4. Establish a vulnerability disclosure program and provide a security.txt file to facilitate responsible reporting of security issues.
  5. Verify and publish domain registration details to improve trustworthiness and transparency.

Technical notes

Notes

The website is built on the SvelteKit framework, leveraging modern JavaScript for dynamic content rendering. It uses Google Adsense for advertising and Senoweb Analytics for tracking user behavior. The site is served over HTTPS, indicating a secure transport layer. Performance is moderate with module preloading and responsive design for mobile devices. However, no CMS or hosting provider information was detected. Accessibility features are basic, and SEO optimization is good with proper meta tags and Open Graph data. There is room for improvement in security headers and privacy compliance to reduce technical risks.
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.
