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

Levý Hradec is a small cultural heritage website dedicated to promoting and educating visitors about the first Christian and political center of the Přemyslid state in the Czech Republic. The site provides historical context, guided tour information, and multimedia content to engage tourists and history enthusiasts. It is positioned as a niche cultural site with local and regional significance. Technically, the website uses modern front-end frameworks such as Foundation 6 and integrates Google Analytics and Tag Manager for visitor tracking. The site is mobile responsive and offers a good user experience with clear navigation and relevant content. However, it lacks visible privacy and cookie policies, security headers, and explicit contact information, which impacts its security posture and privacy compliance. The WHOIS data is unavailable, likely due to privacy protection, which is common for small informational sites. Overall, the website is legitimate and trustworthy but would benefit from improved security and compliance measures.

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 website serves a cultural and educational purpose, targeting tourists, students, and history enthusiasts interested in Czech heritage. It operates as an informational platform without evident commercial transactions or e-commerce. The business model revolves around providing historical knowledge, guided tours, and multimedia content. The site links to local museums, municipal calendars, and Czech Television programs, indicating a partnership ecosystem within the cultural sector. Growth potential lies in expanding digital content and enhancing visitor engagement. The lack of detailed business registration or contact information suggests a small-scale operation, possibly managed by a local cultural organization or municipality.

Security posture

The website demonstrates a basic security posture with HTTPS implied but no explicit security headers detected in the HTML content. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No incident response or security contact information is provided, limiting the site's readiness for security events. The use of Google Analytics and Tag Manager without visible consent mechanisms raises privacy concerns. No vulnerable libraries or exposed sensitive data were identified in the provided content. Overall, the security maturity is low to moderate, suitable for an informational site but requiring improvements to meet modern compliance and security standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including an email address for general and security inquiries.
  4. Conduct a security audit to identify and remediate any vulnerable or outdated libraries.
  5. Enhance transparency about data collection and retention practices related to analytics.

Technical notes

Notes

The website uses Foundation 6 CSS framework and jQuery for front-end development, along with Lightbox for image galleries. Google Analytics and Google Tag Manager are integrated for visitor tracking. The site is mobile responsive and has a clear navigation structure. No CMS or backend technologies were detected from the HTML content. Performance appears moderate with optimized images and responsive design. However, the site lacks advanced accessibility features and SEO optimizations beyond basic meta tags. Hosting provider and SSL configuration details are not available from the provided data. Overall, the technical infrastructure is adequate for a small cultural site but could benefit from modernization and enhanced security configurations.
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.
