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

4 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
    • 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

The company operates in the media sector focusing on audiobook publishing, targeting Czech and international listeners. The business model revolves around content production and e-commerce sales via Shopify. The domain age and WHOIS data align with the company's founding year, supporting legitimacy. The site uses third-party marketing and tracking services to enhance customer engagement and sales. No direct contact information or extensive trust indicators like certifications or testimonials are visible, suggesting a small but focused operation. The partnership with Shopify and use of SECOMAPP for promotional gifts indicates an active approach to customer incentives and marketing.

Security posture

The website enforces HTTPS and uses several third-party scripts for analytics and marketing. However, it relies on older versions of jQuery, which may expose it to known vulnerabilities if not patched. Security headers are not fully visible or implemented, and there is no public vulnerability disclosure or security policy. No incident response contacts or security-specific email addresses are found. The site uses cookie consent mechanisms, indicating some awareness of privacy regulations. Overall, the security posture is moderate but could be improved by updating dependencies, adding security headers, and publishing security policies.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to the latest secure versions.
  2. Implement a comprehensive privacy policy and terms of service pages accessible from the website footer.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security.txt file and vulnerability disclosure policy to improve transparency and incident response readiness.
  5. Review and audit all third-party scripts for privacy compliance and security risks.

Technical notes

Notes

The website is built on Shopify, using Bootstrap 3.x and jQuery libraries for frontend functionality. It integrates Google Tag Manager, Google Analytics, and Adform for marketing and tracking. The site loads scripts asynchronously to improve performance. Hosting is via Shopify's CDN, ensuring good availability and SSL support. Mobile optimization is good, with responsive design and viewport meta tags. SEO is supported by canonical tags and Open Graph metadata. Accessibility is basic but could be enhanced. The site uses several third-party apps such as SECOMAPP for free gifts, indicating a moderately complex e-commerce setup. Performance is moderate, with room for optimization by reducing third-party script load and updating legacy libraries.
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.
