Bubok Publishing, s.l. operates a well-established independent self-publishing platform and online bookstore targeting independent authors and readers interested in self-published works. The company positions itself as a leading independent publisher with a broad network of services including book publishing, distribution, and author promotion. The website reflects a mature digital presence with a professional design, clear navigation, and integration of multiple marketing and analytics tools. Technically, the site uses a mix of legacy and modern web technologies, including jQuery, Bootstrap, Google Tag Manager, and reCAPTCHA Enterprise, ensuring a secure and user-friendly experience.

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

3 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Bubok's market position as a leading independent publisher is supported by its extensive author base and partnerships with major distribution platforms like Amazon and Kobo. Its business model focuses on empowering independent authors with full control over their publishing process, offering flexible publishing packs and services. The company leverages a multi-channel marketing approach including social media, affiliate programs, and trust signals such as Trustpilot reviews. The presence of subsidiaries specializing in audiobooks, author promotion, and adapted reading indicates a diversified service portfolio. Growth indicators include active content updates, new releases, and community engagement through blogs and events. Strategic partnerships and a strong brand identity underpin Bubok's competitive advantage in the self-publishing industry.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and the use of Google reCAPTCHA Enterprise to protect forms from abuse. Cookie consent is managed with granular user controls, reflecting GDPR compliance. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options is a notable gap that could expose the site to certain web-based attacks. The use of outdated jQuery versions may introduce vulnerabilities if not properly patched. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. The absence of a published security policy or incident response contact limits transparency and preparedness communication. Overall, the security posture is good but could be strengthened by implementing recommended headers, updating libraries, and publishing security documentation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  3. Upgrade jQuery and other JavaScript libraries to the latest stable versions to mitigate known vulnerabilities.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website is built on a traditional web stack using jQuery, Bootstrap, and server-side rendered HTML. It integrates modern marketing and analytics tools such as Google Tag Manager, Google Analytics, Facebook Pixel, and Trustpilot widgets. Performance is moderate with use of lazy loading for images and preloading of fonts and key assets. Mobile optimization is good with responsive design elements and mobile-specific menus. Accessibility is basic with some ARIA roles and alt attributes but could be improved. SEO is supported by meta tags, Open Graph tags, and structured navigation. The site does not appear to use a popular CMS like WordPress or Drupal, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security practices.
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.
