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

The website represents the official online presence of the National Museum of the Grand Duchy of Lithuania's Palace, a government cultural institution located in Vilnius, Lithuania. It offers rich content including detailed information about exhibitions, events, educational programs, and virtual tours, targeting museum visitors, tourists, families, and educational institutions. The site is well-structured, professionally designed, and provides multilingual support, enhancing accessibility and user experience. Technically, the website employs modern web technologies such as jQuery, CandyCSS framework, and integrates analytics tools like Google Analytics, Google Tag Manager, and Facebook Pixel. The site is served over HTTPS with good SSL configuration, asynchronous script loading, and demonstrates good mobile optimization and accessibility features. However, there is no explicit cookie consent mechanism, which may impact full GDPR compliance. From a security perspective, the site follows best practices with HTTPS and no visible sensitive data exposure. Security headers are not explicitly detected in the HTML content, suggesting room for improvement. No vulnerability disclosure or incident response information is found, indicating a potential gap in security transparency. Overall, the website is a credible and professional digital asset for a government cultural institution, with strong content quality and business credibility. The absence of WHOIS data limits domain legitimacy verification, but the site’s content and structure strongly indicate authenticity. Strategic improvements in privacy compliance and security headers are recommended to enhance trust and regulatory adherence.

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

7 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: MySQL

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

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 museum operates as a government-funded cultural institution focusing on preserving and presenting Lithuanian heritage through exhibitions, educational activities, and events. Its business model includes public engagement via physical and virtual visits, educational outreach, and e-commerce sales of publications and souvenirs. The museum maintains partnerships with tourism organizations and ticketing platforms, enhancing its market reach. The website’s comprehensive content and event calendar reflect active community involvement and cultural leadership. Growth indicators include expanding virtual offerings and active social media engagement. The museum’s strategic positioning as a national heritage site supports its authoritative market presence in Lithuania’s cultural sector.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and no evident exposure of sensitive information. The use of asynchronous loading for analytics reduces performance impact and potential security risks. However, the lack of explicit security headers such as Content-Security-Policy and absence of a published security.txt file or vulnerability disclosure policy indicate areas for enhancement. No incident response contacts or dedicated security policies beyond data protection are visible, which could limit rapid response capabilities. Compliance with GDPR is indicated through a comprehensive privacy policy, but the missing cookie consent mechanism is a compliance gap. Overall, the security posture is solid but could benefit from formalized disclosure and enhanced header policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Deploy a cookie consent banner or mechanism to ensure full compliance with EU cookie regulations and improve user privacy transparency.
  3. Publish a security.txt file and establish a clear vulnerability disclosure policy to facilitate responsible security reporting and incident management.
  4. Regularly audit third-party scripts and analytics tools for security vulnerabilities and privacy compliance.
  5. Enhance contact information visibility by including verified company emails and phone numbers for visitor support and security incident reporting.

Technical notes

Notes

The website is built on a custom CMS platform utilizing jQuery and the CandyCSS framework for responsive and modern UI design. It integrates Google Fonts for typography and uses asynchronous loading for analytics and tracking scripts to optimize performance. The site is mobile-optimized with good accessibility features such as ARIA labels and keyboard navigation support. SEO is well addressed with meta tags, Open Graph tags, and canonical URLs. Performance is moderate, with potential improvements by optimizing image delivery and caching strategies. The absence of detected hosting provider information limits infrastructure assessment. Overall, the technical implementation supports a professional and user-friendly experience with opportunities for security and privacy enhancements.
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.
