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

Krajská galerie výtvarného umění ve Zlíně is a regional art gallery based in Zlín, Czech Republic, focused on visual arts exhibitions, educational programs, and cultural events. The website serves as an information portal for visitors, schools, and art enthusiasts, providing details about current and upcoming exhibitions, programs for children and schools, and access to online galleries and publications. The institution holds a recognized position in the regional cultural landscape with partnerships including Baťův institut and the Zlínský kraj regional authority. Technically, the website uses a traditional JavaScript framework (MooTools) and Google Fonts, with a moderate performance profile and basic mobile optimization. The site is served over HTTPS with a valid SSL configuration, but lacks advanced security headers, which presents an opportunity for security enhancement. The cookie consent mechanism is implemented, supporting GDPR compliance, and privacy policies are clearly linked. From a security perspective, the site shows a good baseline posture with no visible vulnerabilities or exposed sensitive data. However, the absence of WHOIS data limits the ability to fully verify domain legitimacy and ownership details, slightly reducing trust. No incident response or vulnerability disclosure information is provided, which could be improved to enhance security transparency. Overall, the website is professional, trustworthy, and serves its cultural mission effectively. Strategic improvements in security headers, WHOIS transparency, and incident response readiness would strengthen its security posture and trustworthiness further.

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

11 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. 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 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

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 gallery operates as a public cultural institution, targeting a broad audience including general visitors, students, and educators. Its business model centers on providing art exhibitions and educational programming rather than commercial sales. The presence of partner logos and regional government affiliation indicates stable institutional support. The website content and structure suggest a well-established entity with a focus on regional cultural enrichment. Revenue streams likely include public funding and event-related income. The gallery's digital presence supports outreach and engagement but does not currently leverage advanced marketing or analytics tools. Growth potential lies in expanding digital offerings and enhancing visitor engagement through online platforms.

Security posture

The current security maturity is moderate. HTTPS is enforced, and cookie consent is implemented, indicating awareness of privacy and security requirements. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The site uses older JavaScript libraries (MooTools) which should be regularly audited for vulnerabilities. Overall, the security posture is adequate for a public cultural website but could be improved to meet higher standards and compliance frameworks such as GDPR and NIS2.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly update and audit JavaScript libraries and dependencies to mitigate vulnerabilities.
  4. Enhance WHOIS transparency or provide domain ownership verification to increase trust.
  5. Expand privacy compliance documentation including detailed data retention policies and user rights information.

Technical notes

Notes

The website is built using MooTools JavaScript framework and Google Fonts, indicating a somewhat dated but functional tech stack. The site is served over HTTPS with a valid SSL certificate, ensuring encrypted communications. Performance is moderate with basic mobile optimization and accessibility features. SEO is supported by proper meta tags and structured navigation. No CMS or hosting provider information is explicitly detected. The site could benefit from modernization of its JavaScript framework and implementation of progressive web standards to improve performance and user experience. Security headers are missing, representing a technical risk. Overall, the technical infrastructure supports the business needs but has room for modernization and security hardening.
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.
