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

Flexibooks.cz is a Czech e-commerce platform specializing in the sale of e-books and interactive educational content, operated by Fraus Media, s.r.o. The website offers a broad catalog of over 6,000 titles targeting students, educators, and academic institutions. The business model focuses on digital distribution and licensing of educational materials, positioning itself as a key player in the Czech educational publishing market. Technically, the site uses a mix of legacy JavaScript libraries and modern tools such as Google Tag Manager and cookie consent frameworks, hosted under a Czech registrar and likely Forpsi hosting. Security posture is adequate with HTTPS and cookie consent mechanisms, but could be improved by updating libraries and adding security headers. Privacy compliance is supported by a detailed cookie policy and consent banner, though no explicit privacy policy or terms of service pages were detected in the provided content. Overall, the site is professional and trustworthy but would benefit from enhanced security and compliance documentation.

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, Google APIs

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. 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

The company operates in the education sector with a medium-sized footprint in the Czech Republic. Its competitive advantage lies in a large catalog of digital educational content and interactive textbooks. Revenue streams are primarily from direct e-book sales and licensing. The target customers include schools, teachers, and students. The partnership with Fraus Media and use of ShopCentrik platform indicate a stable operational ecosystem. Growth potential exists through expanding digital offerings and improving user experience. The company maintains good branding consistency and trust signals such as Google site verification and cookie compliance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a comprehensive cookie consent mechanism that respects GDPR principles. However, the use of outdated JavaScript libraries like jQuery 1.10.2 and lack of visible security headers such as Content-Security-Policy or X-Frame-Options represent potential vulnerabilities. No incident response or security contact information is provided, limiting transparency. There is no evidence of a vulnerability disclosure policy or security.txt file. The site does not expose sensitive data in HTML, which is positive. Overall, the security posture is adequate but could be significantly improved by modernizing libraries, adding security headers, and publishing security policies.

Recommendations

  1. Update all JavaScript libraries and plugins to their latest secure versions to mitigate known vulnerabilities.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear privacy policy and terms of service pages accessible from the main navigation or footer.
  4. Add explicit contact information for security incidents and consider publishing a security.txt file.
  5. Enhance mobile optimization and accessibility to improve user experience and compliance.

Technical notes

Notes

The website uses a legacy jQuery version (1.10.2) alongside jQuery UI 1.8.21 and several plugins such as carouFredSel, Thickbox, Lightbox, and Fancybox. Google Fonts and Google Tag Manager are integrated for typography and analytics. The e-commerce platform is ShopCentrik, as indicated in the footer. Performance is moderate with multiple CSS and JS files loaded, some compressed. The site has basic mobile optimization and accessibility features. SEO is supported by meta tags and structured navigation. There is room for modernization by upgrading libraries and optimizing resource loading to improve speed and security.
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.
