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

Národní ústav duševního zdraví (NUDZ) is a Czech national institute focused on mental health research, clinical care, and education. The website serves as a comprehensive portal for their research programs, clinical services, educational offerings, and public mental health initiatives. It targets a general audience including patients, researchers, clinicians, and the public. The organization appears to be a government-affiliated or public institution with a medium-sized operational scale. Technically, the website is built on TYPO3 CMS, uses Alpine.js for interactivity, and integrates Matomo for analytics, reflecting a modern and mature digital infrastructure. Security posture is strong with HTTPS and security headers properly implemented, though some improvements in privacy compliance such as cookie consent are recommended. The absence of WHOIS data reduces domain registration trust but the website content and branding strongly support legitimacy. Overall, the site is professional, accessible, and trustworthy with room for enhanced privacy and contact transparency.

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: Facebook, Twitter, LinkedIn, YouTube, Google APIs

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

    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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

NUDZ holds a strong position in the Czech healthcare sector specializing in mental health. Its business model combines research funding, clinical services, and educational programs. The website indicates multiple research centers and clinical departments, suggesting diversified revenue streams including grants and patient services. The target customers include patients, healthcare professionals, researchers, and educators. The organization maintains an active social media presence and partners with recognized entities such as WHO. The lack of WHOIS transparency is a minor concern but does not detract from the evident institutional credibility. Growth indicators include ongoing conferences, research projects, and public mental health support initiatives.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible vulnerabilities or exposed sensitive data. Use of Matomo analytics respects privacy better than many commercial alternatives. However, the absence of a cookie consent mechanism and explicit security policy or incident response information are gaps in compliance and transparency. No vulnerability disclosure or security.txt files were found, limiting external security engagement. Incident response readiness and security culture indicators are not publicly visible. Overall, the site is secure but could improve transparency and user privacy controls.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and enhance user trust.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance visibility and accessibility of contact information including phone and email for general and security inquiries.
  5. Consider WHOIS data publication or domain registration transparency to improve domain trustworthiness.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, ensuring scalability and maintainability. Frontend interactivity is handled by Alpine.js, a lightweight JavaScript framework. Analytics are managed via Matomo, a privacy-focused platform, and Google Maps API is used for location services. The site is mobile-optimized with good accessibility features and SEO meta tags. Performance is moderate, likely due to rich media content and multiple fonts. No deprecated or vulnerable libraries were detected. The technical stack is modern and well-implemented, with opportunities to improve performance and privacy compliance.
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.
