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

Regionální muzeum v Mikulově is a regional cultural institution operating multiple heritage sites and museums in the South Moravian region of the Czech Republic. The organization provides exhibitions, educational programs, and cultural events targeting local residents, tourists, and families. The website reflects a well-established public institution affiliated with the regional government, offering comprehensive cultural services and digitalized collections. Technically, the website uses modern web technologies including Bootstrap, jQuery, Google Analytics, and Google Tag Manager, ensuring a responsive and user-friendly experience. However, some areas such as cookie consent and security headers could be improved to enhance compliance and security. The security posture is generally good with HTTPS enabled and no visible vulnerabilities, but lacks explicit security policies and incident response information. Overall, the website is professional, trustworthy, and serves its public cultural mission effectively.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 museum holds a strong position as a regional government-affiliated cultural institution with multiple branches and partner sites. Its business model is non-profit and government-funded, focusing on cultural preservation, education, and tourism. The presence of multiple external partner domains and social media channels indicates an active engagement with the community and visitors. The museum leverages digital tools for outreach and marketing but could enhance transparency around privacy and security. Growth opportunities may include expanding digital collections and improving online user engagement. The museum's operations are consistent with public sector cultural institutions, with a medium organizational size and a clear focus on regional heritage.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no exposed sensitive data. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth posture. No vulnerability disclosures or incident response contacts are published, which may hinder rapid response to security incidents. GDPR compliance is partially addressed via a dedicated GDPR page, but cookie consent mechanisms are missing. The use of third-party analytics and marketing scripts introduces potential privacy risks if not properly managed. Overall, the security posture is adequate for a public cultural website but could benefit from enhanced policies, headers, and user privacy controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  2. Add a cookie consent banner to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and readiness.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities and privacy risks.
  5. Enhance website accessibility features to meet modern standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a Bootstrap framework with jQuery and integrates Google services such as Tag Manager, Analytics, and Custom Search Engine. It uses Mailchimp for newsletter signup popups. The site is mobile responsive and has a moderate performance profile. SEO is basic with proper meta tags and language attributes but could be improved with structured data and richer metadata. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not available. The site lacks advanced accessibility features and security headers, indicating areas for modernization and technical debt reduction.
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.
