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

Nakladatelství GRADA Publishing, a.s. operates the website www.grada.cz, a professional e-commerce platform specializing in the sale of books, e-books, and audiobooks primarily targeting the Czech market. The website offers a wide range of literary genres including stress-relief coloring books, fiction, children's literature, personal development, and healthcare literature. The platform is positioned as a leading Czech book publisher and retailer, providing customers with free gifts on book orders, enhancing customer engagement and loyalty. Technically, the website employs a custom CMS with modern JavaScript libraries such as jQuery and Vue.js templates, and integrates third-party analytics and marketing tools including Google Tag Manager and Luigis box. The site is served over HTTPS with a strong SSL configuration, ensuring secure data transmission. Mobile optimization and SEO practices are good, although accessibility features are basic. The site uses cookie consent mechanisms, indicating some level of privacy compliance. From a security perspective, the site lacks visible security headers which could enhance protection against common web vulnerabilities. No sensitive data exposure or vulnerable libraries were detected in the provided content. The absence of WHOIS data limits the ability to fully verify domain legitimacy, but the website content and technical indicators suggest a legitimate and professional business presence. Overall, the website presents a solid e-commerce platform with good content quality and technical implementation. Strategic improvements in privacy policy visibility, security headers, and domain registration transparency would strengthen trust and compliance 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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

GRADA Publishing is a significant player in the Czech book publishing and retail market, leveraging an e-commerce model to reach a broad audience. Their business model focuses on direct online sales of printed and digital books, supplemented by audiobooks. The company targets general consumers interested in various literary genres, including educational and healthcare materials. The website's integration with popular Czech shopping comparison services like Heureka.cz indicates a strong partnership ecosystem. The use of multiple marketing and analytics tools suggests an emphasis on data-driven customer engagement and sales optimization. The lack of explicit contact information on the site may be a minor barrier to customer trust but does not detract significantly from their market position.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and no apparent exposure of sensitive information. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a missed opportunity to harden the site against common attacks like clickjacking and MIME sniffing. No vulnerability disclosures or incident response contacts are visible, which could be improved to enhance security transparency and readiness. Privacy compliance is partial, with cookie consent implemented but no clear privacy or terms of service pages found. Overall, the security maturity is adequate for an e-commerce site but could benefit from enhanced policies and technical controls.

Recommendations

  1. Implement and publicly link a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to strengthen site security.
  3. Publish clear contact information including security incident response channels to improve transparency and readiness.
  4. Ensure WHOIS domain registration data is complete and publicly accessible to enhance domain legitimacy and trust.
  5. Conduct regular security audits and vulnerability assessments to proactively identify and mitigate risks.

Technical notes

Notes

The website uses a custom CMS platform with integration of modern JavaScript libraries such as jQuery and Vue.js for dynamic content rendering. It leverages Google Tag Manager and Luigis box for analytics and marketing, and includes PDF.js for document handling. The site is optimized for mobile devices and includes SEO best practices such as meta tags and Open Graph data. Performance is moderate, with asynchronous loading of scripts and preconnect hints to external resources. However, the lack of visible security headers and incomplete WHOIS data indicate areas for technical improvement. The site does not appear to use a common CMS like WordPress or Joomla, suggesting a bespoke or enterprise solution.
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.
