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

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

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 occupies a niche market in the Czech Republic focusing on educational and nature-related books, leveraging an e-commerce model with pre-orders, discounts, and affiliate marketing partnerships. Its competitive advantage lies in curated content with a strong thematic focus and a family-friendly approach. Revenue streams include direct book sales, audiobooks, e-books, and affiliate commissions. The target customers are families, educators, and individuals interested in popular science and nature. The presence of an affiliate program and AI-enhanced search indicates a forward-looking digital strategy. Partnerships with Dognet affiliate network and use of multiple marketing and analytics tools suggest active marketing efforts. The company appears small-sized with a focused market presence and no visible parent or subsidiary companies beyond an e-library subdomain.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, cookie consent banners compliant with GDPR, and use of CSRF tokens in forms. Security headers are implied but not explicitly confirmed, and no vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms represents a compliance gap. The use of multiple third-party scripts requires ongoing monitoring for vulnerabilities. Overall, the site is secure for typical e-commerce operations but could improve transparency and readiness by publishing security policies and incident response information.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Implement and verify security headers such as X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  3. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all users.

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.
