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

Nakladatelství Jota, s.r.o. is a Czech publishing company operating an e-commerce platform specializing in a wide range of books including fiction, non-fiction, audiobooks, and e-books. The company targets Czech-speaking readers with diverse literary interests and maintains a professional online presence with clear contact information and active social media engagement. The website is well-designed, mobile-optimized, and provides comprehensive product information and customer engagement features such as newsletters and event calendars. Technically, the site employs modern tracking and advertising technologies including Google Tag Manager, Google Analytics, Facebook Pixel, and Leadhub Pixel, indicating a mature digital marketing strategy. Security posture is generally good with HTTPS enforced and no visible sensitive data exposure, though the absence of security headers suggests room for improvement. Privacy and cookie policies are present and GDPR compliant, reflecting attention to regulatory requirements. The lack of WHOIS data limits domain trust assessment, but the overall professionalism and transparency of the site support a positive legitimacy evaluation.

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

7 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

      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

  2. 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

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 holds a solid position in the Czech retail book market, offering a broad catalog that spans multiple genres and formats. Its business model centers on direct online sales supported by digital marketing and customer engagement tools. The presence of bestseller tags and preorder options suggests active inventory and sales management. The company leverages social media platforms for brand visibility and customer interaction. While no explicit partnerships or subsidiaries are identified, the site links to major social media and content platforms. The business appears medium-sized with a focus on retail and publishing sectors. Growth potential is supported by diversified product offerings and event-driven marketing. The absence of detailed WHOIS data is a minor concern but does not detract significantly from the business credibility.

Security posture

The website demonstrates a good security baseline with HTTPS and no exposed sensitive information in the HTML content. The use of asynchronous loading for third-party scripts reduces page load impact and potential blocking. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is a gap that could be exploited in certain attack scenarios. No vulnerability disclosure or security policy pages are present, which could hinder incident response transparency. The site complies with GDPR through privacy and cookie policies, indicating awareness of data protection obligations. Overall, the security posture is adequate for an e-commerce retail site but would benefit from enhanced header configurations and a formal vulnerability disclosure mechanism.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to strengthen defense against common web attacks.
  2. Establish a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting and improve incident response readiness.
  3. Regularly audit and update third-party scripts and tracking pixels to mitigate risks from vulnerable dependencies.
  4. Enhance accessibility features to improve usability for users with disabilities and comply with accessibility standards.
  5. Consider publishing more detailed business and security information to increase transparency and trust with customers.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager, Google Analytics, Facebook Pixel, and Leadhub Pixel for analytics and marketing. The front-end employs Swiper.js for interactive carousels and Bootstrap Icons for UI elements. The site is mobile responsive and well-structured with clear navigation menus and search functionality. Performance is moderate with asynchronous script loading to optimize page speed. No CMS or hosting provider information is explicitly detected. SEO is supported by appropriate meta tags and structured navigation. Accessibility is basic but could be improved. The site does not expose sensitive data and uses HTTPS exclusively, indicating good technical hygiene. Opportunities exist to enhance security headers and formalize vulnerability disclosure processes.
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.
