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

Palmknihy.cz is a large Czech online bookstore operated by Etnetera, offering over 100,000 printed and electronic books including audiobooks. The website targets Czech-speaking readers and provides fast shipping and promotional discounts. Technically, the site employs modern web technologies including JavaScript frameworks, SCSS, and integrates multiple third-party analytics and marketing tools such as Google Analytics, Smartlook, Persoo, and Cookiebot for GDPR-compliant cookie consent management. Security posture is solid with HTTPS enforced and nonce attributes used in scripts, though some security headers are not explicitly visible in the HTML. Privacy compliance is good with a comprehensive cookie consent mechanism, but no explicit privacy or terms of service pages were found in the provided content. Overall, the website is professional, trustworthy, and safe for general audiences.

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

2 findings rated critical or high. Fix these first.

  1. 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

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Palmknihy.cz holds a strong market position in the Czech online retail book sector, leveraging a broad catalog and fast delivery to attract customers. The business model focuses on e-commerce sales of printed and digital books, supported by extensive marketing and retargeting via multiple ad networks. The company benefits from partnerships with major advertising platforms and uses advanced personalization tools. The absence of visible contact information or detailed corporate disclosures in the HTML suggests these may be located elsewhere or require deeper inspection. The website's branding is consistent and content quality is good, supporting a positive user experience.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of nonce attributes to mitigate script injection risks. Cookie consent is granular and GDPR compliant, indicating good privacy practices. However, explicit security headers like X-Frame-Options and X-Content-Type-Options are not visible in the HTML and should be verified server-side. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Incident response and security policy information are not present, which could be improved to enhance transparency and readiness.

Recommendations

  1. Implement and verify security headers such as X-Frame-Options and X-Content-Type-Options to strengthen browser security.
  2. Publish clear privacy policy and terms of service pages accessible from the homepage to improve compliance and user trust.
  3. Provide explicit contact information including emails and phone numbers for customer support and security incident reporting.
  4. Conduct regular audits of third-party scripts and marketing tools to ensure no vulnerabilities or privacy issues arise.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern technology stack with SCSS for styling and multiple JavaScript libraries for analytics, marketing, and user interaction. Google Tag Manager, Smartlook, Persoo, and Cookiebot are integrated for tracking and consent management. The site preloads critical resources and images for performance optimization. Mobile optimization is good, and SEO meta tags including Open Graph and Twitter cards are well implemented. Hosting provider details are not explicit in the HTML. Performance is moderate with room for improvement in accessibility and some technical SEO aspects.
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.
