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

The website 'Observatoř bezpečnosti silničního provozu' is a Czech Republic-based platform operated by the Centrum dopravního výzkumu, v. v. i., focused on providing comprehensive information and research data to improve road safety. It serves government bodies, local authorities, and traffic safety professionals by offering data, surveys, educational content, and strategic insights. The site is well-structured with clear navigation and professional design, supporting its role as an authoritative resource in the transportation safety sector. Technically, the website employs a modern tech stack including Bootstrap, jQuery, and various JavaScript libraries for data visualization and user interaction. It uses Google Analytics and Tag Manager for traffic analysis and implements cookie consent mechanisms compliant with GDPR. The site is mobile-optimized and performs moderately well, though there is room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS and uses secure login forms but lacks explicit security headers such as CSP and HSTS, which are recommended to enhance protection. No WHOIS data was retrievable, which slightly impacts trust assessment, but the website's content and external references strongly indicate legitimacy. No adult or questionable content is present, making it safe for general audiences. Overall, the website demonstrates a solid business and technical foundation with moderate security posture. Strategic improvements in security headers, WHOIS transparency, and accessibility would further strengthen its trustworthiness and compliance.

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

9 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

  2. Security headers

    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 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

The platform occupies a significant niche in the Czech transportation safety ecosystem, supported by the Ministry of Transport and linked with multiple research and safety organizations. Its business model centers on information dissemination and research support rather than commercial transactions. The site’s partnerships with government and research institutions enhance its credibility and reach. The target audience includes policymakers, safety auditors, and the expert public, indicating a specialized but important market segment. The presence of surveys and interactive content suggests engagement strategies to gather data and feedback. The lack of WHOIS data is a minor anomaly but does not detract from the site's established institutional backing.

Security posture

The website maintains a basic to moderate security posture with HTTPS enabled and secure login forms. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces its defense-in-depth. No evidence of exposed sensitive data or vulnerable libraries was found in the provided content. Cookie consent and privacy policy implementation indicate awareness of privacy compliance. Incident response and vulnerability disclosure information are not present, which could be improved to enhance security readiness and transparency. Overall, the site is secure for its informational purpose but would benefit from adopting additional security best practices.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish explicit security and incident response policies to improve transparency and readiness.
  3. Improve accessibility features to meet modern standards and enhance user experience for all visitors.
  4. Enhance WHOIS data availability or domain registration transparency to increase trustworthiness.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a custom CMS likely based on the Nette Framework, combined with popular frontend libraries such as Bootstrap and jQuery. It integrates advanced visualization tools like D3.js and C3.js for data presentation. Google Analytics and Tag Manager are used for traffic monitoring. The site is mobile responsive and has a clear navigation structure. Performance is moderate, with potential improvements in load times and script optimization. The absence of certain security headers and limited accessibility features represent technical debt. Hosting details are not explicitly available, but the site uses HTTPS with a valid certificate. Overall, the technical infrastructure supports the site's informational goals effectively but could be modernized further for security and performance.
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.
