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

Centrum vzdělávání, informací a kultury Český Brod is a local public institution combining educational, informational, and cultural services including a municipal library, information center, and cultural house. The website serves as a portal for event calendars, ticket sales, photo galleries, and official communications targeting the local Czech community. The business model is focused on community engagement and cultural enrichment rather than commercial activities. Technically, the website employs a modern frontend stack with Bootstrap, jQuery, FontAwesome, and other libraries, ensuring a responsive and user-friendly experience. Google Tag Manager is used for analytics and marketing tracking, with a cookie consent mechanism implemented to comply with GDPR requirements. The site is well-structured with clear navigation and accessible contact options. From a security perspective, the site uses HTTPS and has implemented cookie consent controls, but lacks visible HTTP security headers and explicit security or incident response policies. The WHOIS data is incomplete and malformed, which reduces domain trustworthiness, but the website content and contact information appear legitimate and consistent with a public cultural institution. Overall, the website is functional, professional, and trustworthy for its intended audience, but improvements in security headers, WHOIS transparency, and explicit security policies would enhance its security posture and compliance.

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

13 findings rated critical or high. Fix these first.

  1. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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
    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP 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

  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
      • 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

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 organization operates as a small-sized essential public entity in the education and culture sector within the Czech Republic. It holds a strong local market position as a cultural and educational hub, offering library services, event organization, and information dissemination. The business model is non-commercial, focusing on community service and cultural promotion. The website reflects a consistent brand and provides clear contact information, event calendars, and galleries, indicating active engagement with its audience. Partnerships with local cultural sites and ticketing platforms are evident. Growth indicators are limited due to the public service nature, but the site maintains good digital presence and user engagement.

Security posture

The current security maturity is moderate. HTTPS is enabled, and cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or security policy information is provided, limiting transparency and preparedness. The WHOIS data is incomplete, which may raise concerns about domain legitimacy. No vulnerabilities or exposed sensitive data were detected in the content. Enhancing security headers, publishing security policies, and improving WHOIS transparency would strengthen the security posture.

Recommendations

  1. Implement standard HTTP security headers (CSP, HSTS, X-Frame-Options) to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Audit and update SSL/TLS configuration to ensure strong encryption and compliance with best practices.
  4. Improve WHOIS data completeness and transparency to enhance domain trustworthiness.
  5. Maintain and regularly review cookie consent and privacy compliance mechanisms to align with evolving regulations.

Technical notes

Notes

The website uses a modern and widely adopted frontend technology stack including Bootstrap 4.3.1, jQuery, FontAwesome, SweetAlert, Slick Carousel, and JustifiedGallery, ensuring responsive design and interactive features. Google Tag Manager is integrated for analytics and marketing purposes. The site is mobile-optimized with good navigation clarity and user experience. However, no CMS or backend platform was identified from the provided data. Performance is moderate, with potential for optimization. Accessibility features are basic but present. The lack of visible security headers and incomplete WHOIS data represent technical risks that should be addressed to improve overall site security and trust.
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.
