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. 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

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    • 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
  • 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

VHÚ holds a strong market position as the official Slovak military historical institute, supported by government funding and partnerships with ministries of defense, interior, culture, and education. Its business model focuses on public service, research, and education rather than commercial revenue. The target audience includes academic researchers, military history enthusiasts, and the general public. The website's content quality and navigation support effective dissemination of information and engagement with stakeholders. Partnerships with government bodies and cultural institutions strengthen its ecosystem. The absence of commercial advertising and affiliate programs aligns with its non-profit government status. Growth indicators include active event announcements, exhibitions, and publication updates. Strategic observations suggest opportunities to enhance security policies publication and incident response readiness to further improve institutional trust.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms that comply with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, or HSTS were not observed, representing an area for improvement. There is no published security policy or incident response contact information, which could enhance transparency and preparedness. The use of deferred and async loading of scripts improves performance and reduces attack surface. Overall, the security maturity is good but could benefit from formalizing security policies and vulnerability disclosure mechanisms.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and HSTS to strengthen defense-in-depth.
  2. Publish a formal security policy and incident response contact information on the website to improve transparency and readiness.
  3. Add a security.txt file or vulnerability disclosure page to encourage responsible reporting of security issues.
  4. Regularly audit third-party libraries and scripts to ensure no vulnerabilities are introduced.
  5. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.

Technical notes

Notes

The website is built on the SysCom CMS platform, leveraging Bootstrap 5 for responsive design and user interface components. It uses Swiper.js for carousel functionality and Fancybox for image galleries, both loaded via CDN with deferred script loading to optimize performance.

The site includes accessibility features such as skip links and ARIA labels, enhancing usability for assistive technologies. Performance is moderate with some room for optimization, particularly in script loading and caching strategies. The site is mobile-optimized and SEO-friendly with proper meta tags and structured navigation. No hosting provider details were identified from the HTML content. Overall, the technical infrastructure supports a professional and user-friendly experience with modern web standards.
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.
