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.

Priority findings

6 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

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

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 business model centers on empowering independent authors through self-publishing and distribution services, targeting novice and experienced writers in Spanish-speaking markets. The company leverages a multi-channel distribution network including major retailers like Amazon, Kobo, and physical bookstores, enhancing reach and sales potential. Its ecosystem includes subsidiaries focused on audiobook generation, author promotion, accessible reading formats, and co-editing services, indicating strategic diversification. The platform's revenue streams likely include publishing fees, editorial services, and book sales commissions. Bubok's competitive advantage lies in its comprehensive service offering, strong community engagement, and established market presence. The company maintains active social media and marketing efforts, supported by analytics and retargeting tools. Growth indicators include a large author base and continuous content updates. Partnerships with distributors and bookstores further solidify its market position.

Security posture

The website exhibits a solid security posture with mandatory HTTPS, use of reCAPTCHA Enterprise to mitigate automated abuse, and integration of security-related HTTP headers to control caching and browser compatibility. However, the absence of advanced headers like Content-Security-Policy and X-Frame-Options suggests potential areas for improvement. The use of an older jQuery version may expose the site to known vulnerabilities if not properly patched. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Privacy policies and cookie consent mechanisms align with GDPR requirements, indicating compliance awareness. Incident response and vulnerability disclosure information are not publicly available, which could be enhanced to improve transparency and trust. Overall, the security measures are adequate for the business type but could benefit from modernization and expanded security controls.

Recommendations

  1. Implement additional security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to strengthen browser security.
  2. Upgrade jQuery and other JavaScript libraries to the latest stable versions to mitigate known vulnerabilities.
  3. Publish a clear vulnerability disclosure policy and incident response contact information to enhance transparency and security posture.
  4. Enhance accessibility features to improve compliance with standards and user experience for all users.
  5. Regularly review and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website uses a combination of Bootstrap for responsive design and jQuery 1.9.1 for DOM manipulation, which is somewhat outdated but functional. Analytics are handled via Matomo and Google Analytics, with Google Tag Manager orchestrating tags. Facebook Pixel is used for marketing and retargeting. The site loads fonts and images with preload hints to optimize performance. The presence of lazy loading for images and videos indicates performance optimization efforts. The site is mobile-optimized with a clear navigation structure and multiple interactive elements such as carousels and dropdown menus. However, the use of older jQuery and lack of modern JavaScript frameworks suggests some technical debt. Hosting provider details are not discernible from the content. Overall, the technical infrastructure supports a good user experience but could be modernized for improved security and maintainability.
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.
