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

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

      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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

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 · found on this site
  • 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 National Heritage Institute holds a strong market position as the largest heritage conservation organization in the Czech Republic, funded by the government. Their business model focuses on managing state-owned monuments, organizing public exhibitions and events, and publishing heritage-related materials. The target audience includes tourists, heritage professionals, and the general public interested in cultural heritage. The organization maintains a robust social media presence and offers an e-commerce platform for publications, indicating diversified engagement channels. The domain age and registration details support the legitimacy and stability of the organization. No suspicious or privacy-protected WHOIS data is present, reinforcing transparency.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and cookie consent mechanisms in place. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the provided HTML, which could be improved. No vulnerability disclosure or incident response information is published, which is a gap in security transparency. No exposed sensitive data or vulnerable libraries were detected. The site lacks a published security policy or contact channels for security incidents. Overall, the security posture is adequate for a government website but could benefit from enhanced headers and published policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Provide explicit contact information including emails and phone numbers for general and security inquiries.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager and Analytics for tracking, Leaflet.js for interactive maps, and web fonts from Typekit and Google Fonts. The HTML structure is valid and includes meta tags for SEO and social sharing (Open Graph and Twitter cards). The site is mobile responsive and has good navigation clarity. Performance appears moderate based on the use of multiple external resources and scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Overall, the technical implementation is solid but could be optimized further for performance and accessibility.
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.
