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

Ceneo.pl is a leading Polish price comparison and product review platform specializing in consumer electronics, home appliances, and various retail categories. The website offers users the ability to find products, compare prices across multiple online shops, and read reviews to make informed purchasing decisions. It targets Polish consumers and operates as a large-scale e-commerce service provider in Poland. Technically, the site employs modern JavaScript frameworks such as RequireJS and Preact, integrates with Google Analytics and Microsoft Application Insights for tracking and performance monitoring, and uses Google Tag Manager for marketing and analytics management. The site is well-structured with good SEO practices and mobile optimization. Security-wise, the site enforces HTTPS and uses anti-forgery tokens and CAPTCHA v3 for form protection, though explicit security headers are not evident in the HTML content. Privacy and cookie policies are not clearly found in the provided content, indicating room for improvement in compliance transparency. WHOIS data for the domain is not publicly available, which is typical for commercial Polish domains but limits direct verification of registrant details. Overall, Ceneo.pl presents a professional, trustworthy, and technically mature e-commerce platform with moderate privacy compliance and good security 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

3 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Ceneo.pl holds a strong market position as a top price comparison website in Poland, serving a broad consumer base interested in electronics, home goods, and lifestyle products. Its business model revolves around aggregating product offers from partner online shops, providing price comparison, and facilitating user reviews. Revenue streams likely include advertising, affiliate commissions, and promoted product placements. The platform integrates with numerous partner domains, including major retailers and specialty shops, enhancing its ecosystem. Growth indicators include extensive product listings, active promotions, and advanced analytics usage. The company demonstrates a mature digital presence with strategic use of marketing and tracking tools, though explicit corporate details and certifications are not publicly disclosed in the analyzed content.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement, use of anti-forgery tokens in forms, and CAPTCHA v3 integration to mitigate automated abuse. Tracking and analytics scripts are loaded asynchronously to optimize performance and reduce attack surface. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options in the HTML content suggests potential areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the provided content. Incident response and security policy documents are not found, indicating a gap in transparency and readiness communication. Overall, the security posture is good but could benefit from formalized policies and additional header implementations.

Recommendations

  1. Publish clear and accessible privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and verify security headers including CSP, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  3. Provide explicit security incident response contact information and policies to enhance transparency and readiness.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses a modern JavaScript-based front-end architecture with RequireJS for module loading and Preact for UI components. It integrates multiple analytics and marketing tools such as Google Analytics, Microsoft Application Insights, and Google Tag Manager. Lazy loading of images is implemented via LazySizes to improve performance. The site is mobile optimized and uses semantic HTML with meta tags for SEO. However, no CMS is explicitly detected, and hosting provider details are not available. Performance is moderate with asynchronous script loading but could be improved with additional optimization. The technical stack is robust and supports a large-scale e-commerce platform but would benefit from enhanced security header configurations and clearer compliance documentation.
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.
