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

5 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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

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

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The institution holds a leading position in the Czech transport research market, serving public sector clients and industry stakeholders. Its business model revolves around research, consultancy, diagnostics, and training services. The presence of multiple accreditations and certifications, along with media coverage, enhances its credibility. The organization actively engages in knowledge dissemination through publications, events, and a YouTube channel. Partnerships with related domains like metodickecentrum.cz and kombinovanapreprava.cz indicate a collaborative ecosystem. The website's content and service offerings reflect a focus on sustainable and intelligent transport solutions, aligning with contemporary trends and government priorities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options suggests potential gaps in defense-in-depth. The use of third-party scripts like analytics and social media pixels requires ongoing monitoring to mitigate privacy and security risks. There is no evidence of an incident response policy or vulnerability disclosure program publicly available, which could be areas for enhancement. Overall, the security posture is adequate for a public research institution but could benefit from additional hardening and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Establish and publish an incident response and vulnerability disclosure policy to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities and privacy risks.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Verify and publish complete WHOIS registration data to strengthen domain legitimacy and trust.

Technical notes

Notes

The website employs a modern technology stack with Bootstrap for responsive design, jQuery for DOM manipulation, Font Awesome for icons, and Google Fonts for typography. It integrates Google Analytics and Facebook Pixel for user tracking and marketing analytics. The use of Revolution Slider and Flatpickr enhances UI interactivity. Performance appears moderate with preloading of fonts and deferred script loading. Mobile optimization is good, with responsive navigation and layout adjustments. SEO is supported by appropriate meta tags and Open Graph data. However, no CMS was explicitly detected, suggesting a custom or proprietary solution. Hosting provider details are not evident from the content. Technical risks include reliance on multiple third-party scripts and lack of visible security headers, which could impact security 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.
