Risk levelMedium

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

OneHotBook is a Czech audiobook publishing company specializing in producing audiobooks from contemporary Czech and international authors. The company offers comprehensive professional production services including dramaturgy, direction, music, postproduction, and design. The website is built on the Shopify platform, leveraging modern web technologies and third-party marketing and analytics tools. The technical infrastructure is solid with HTTPS and CDN hosting, though some security best practices such as explicit security headers and published privacy policies could be improved. The security posture is moderate, with no critical vulnerabilities detected but lacking some transparency in incident response and data protection. Overall, the website presents a professional and trustworthy front for a niche media business with room for enhancement in privacy compliance and security disclosures.

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 in the Czech Republic. Its business model revolves around producing and selling audiobooks with full production services. The domain age and WHOIS data support a stable business presence since 2012. The website targets audiobook listeners and buyers, primarily in the Czech market. The use of Shopify and integration with marketing tools like Adform and Yotpo indicates a focus on e-commerce and customer engagement. No direct contact details or extensive trust signals such as certifications or testimonials were found, suggesting potential areas for growth in customer trust and transparency.

Security posture

The website enforces HTTPS and uses standard Shopify security infrastructure. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No vulnerability disclosure or incident response information is published, which limits the ability to handle security incidents transparently. The presence of multiple third-party scripts requires ongoing vigilance to avoid supply chain risks. Cookie consent is implemented, indicating some GDPR awareness, but no detailed privacy policy was found. Overall, the security maturity is moderate but could be enhanced with better policy publication and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer.
  2. Implement and verify security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  3. Add visible contact information including security incident response contacts (e.g., security@ or abuse@ emails).
  4. Review and audit third-party scripts regularly to minimize supply chain risks.
  5. Enhance GDPR compliance by detailing data retention policies and user rights in privacy documentation.

Technical notes

Notes

The website uses Shopify as its CMS and e-commerce platform, with Bootstrap 3.x and jQuery for frontend UI components. It integrates Google Analytics, Google Tag Manager, Adform tracking, and Yotpo for reviews, indicating a mature marketing stack. Hosting is via Shopify CDN, providing good performance and availability. The site is mobile optimized and uses asynchronous script loading to improve page load times. However, some legacy libraries like jQuery 1.9.1 are still in use, which may pose security risks. Accessibility features are basic, and SEO is supported by proper meta tags and Open Graph data. Overall, the technical infrastructure is solid but could benefit from modernization and enhanced security controls.
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.
