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

Nakladatelství Kodudek is a small Czech publishing house specializing in cultural, historical, and literary works, including archaeological studies and classic literature such as Hans Christian Andersen's stories. The website reflects a niche cultural publisher with a focused audience interested in Czech heritage and academic publications. The business model centers on book publishing and cultural collaborations, supported by social media presence on Twitter and Facebook. Technically, the website uses standard web technologies including jQuery and Google Analytics, with moderate performance and basic mobile optimization. Security posture is average, with HTTPS implied but lacking explicit security headers and no visible privacy or cookie policies, which impacts compliance and trust. The absence of WHOIS data reduces domain trustworthiness, though the website content and social media presence support legitimacy. Overall, the site is professional and content-rich but would benefit from improved privacy compliance and security hardening.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 a niche cultural publishing market in the Czech Republic, targeting readers interested in specialized cultural and historical content. Their competitive advantage lies in focused academic and cultural publications and collaborations with cultural institutions. Revenue likely derives from book sales and exhibition partnerships. The website's limited contact information and lack of detailed corporate data suggest a small-scale operation. The partnership ecosystem includes cultural institutions and web design services. Growth indicators are not explicit but the presence of recent publications and social media activity indicate ongoing operations. Strategic observations include the need for enhanced digital presence and compliance to support market credibility.

Security posture

The website demonstrates a basic security maturity level. HTTPS is used, but no security headers such as Content Security Policy or HSTS were detected. There are no visible forms collecting sensitive data, reducing immediate risk exposure. However, the lack of privacy and cookie policies indicates compliance gaps with GDPR and other data protection regulations. Incident response and security policies are not published, suggesting limited formal security governance. The use of Google Analytics introduces moderate user tracking without visible consent mechanisms, which is a privacy concern. Overall, the security posture is functional but requires improvements in policy transparency, header implementation, and privacy compliance to reduce risk and enhance trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies with GDPR compliance and visible consent mechanisms.
  2. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Publish clear contact information including company emails and phone numbers to enhance business credibility.
  4. Conduct a WHOIS domain registration update or privacy disclosure to improve domain trustworthiness.
  5. Improve mobile optimization and accessibility features to enhance user experience and SEO.

Technical notes

Notes

The website uses a traditional web stack with jQuery and Google Analytics for tracking. Google Fonts are used for typography. The site loads CSS and JavaScript via gzip compression, indicating some performance optimization. However, mobile optimization is basic and accessibility features are minimal. No CMS or advanced frameworks were detected, suggesting a custom or static site approach. Hosting provider details are not available. Performance is moderate with no critical technical debt visible. Opportunities exist to modernize the tech stack, improve SEO metadata, and enhance accessibility compliance to support broader audience reach and better search engine rankings.
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.
