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

Biblion.cz is a Czech e-commerce bookstore specializing in spiritual and Christian literature, offering a variety of books, e-books, audiobooks, and gift vouchers. The website is built on the Shoptet platform, integrating common marketing and analytics tools such as Google Tag Manager and Facebook SDK. The site is well-structured with good content quality and user experience, targeting Czech-speaking customers interested in religious and spiritual books. However, the absence of WHOIS registration data and lack of explicit privacy and terms of service pages reduce trust and compliance confidence. The use of an outdated jQuery version poses a security risk that should be addressed. Overall, the site demonstrates moderate technical maturity and security posture but would benefit from enhanced transparency and updated technology.

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

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

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

    • High

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

Biblion operates in a niche retail segment focused on spiritual and Christian literature within the Czech Republic. Its business model centers on online sales through a specialized e-commerce platform. The company leverages digital marketing and analytics tools to engage its audience but lacks visible direct contact details and formal policy disclosures, which may impact customer trust. The presence of a dedicated blog subdomain suggests content marketing efforts. The business appears small-sized with a focused target audience and a consistent brand presence. Growth opportunities include improving compliance transparency and modernizing technical infrastructure.

Security posture

The website enforces HTTPS and includes cookie consent mechanisms, indicating baseline security and privacy awareness. However, the use of an outdated jQuery library version introduces potential vulnerabilities. No explicit security headers were confirmed, and no incident response or vulnerability disclosure information is published. The absence of WHOIS registrant data raises concerns about domain legitimacy and transparency. Overall, the security posture is moderate but requires improvements in technology updates, policy disclosures, and security best practices to reduce risk and enhance trust.

Recommendations

  1. Upgrade jQuery and other JavaScript libraries to current supported versions to mitigate known vulnerabilities.
  2. Publish comprehensive privacy policy and terms of service pages accessible from the website footer or main navigation.
  3. Implement and verify security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Provide clear contact information including company emails and phone numbers to improve business credibility.
  5. Establish and disclose an incident response process and vulnerability disclosure policy to enhance security transparency.

Technical notes

Notes

The website uses the Shoptet e-commerce platform with a tech stack including jQuery 1.11.3, Google Tag Manager, Facebook SDK, Swiper.js for carousels, and Flatpickr for date inputs. Hosting appears to leverage CDN services such as Cloudfront and Shoptet's own CDN. The site is mobile-optimized with responsive design and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. Performance is moderate, with some room for improvement by updating libraries and optimizing assets. The technical implementation is solid for a small retail site but shows signs of technical debt due to outdated 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.
