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

8 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

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 company targets municipal and regional public transport providers in the Czech Republic, positioning itself as a niche supplier of specialized safety and monitoring systems. Their business model revolves around system design, certification, installation, and operational testing. The presence of references from major Czech transport operators indicates established partnerships and credibility within the local market. However, the lack of visible contact information and privacy policies on the website may limit customer engagement and trust. The company leverages partnerships with vehicle manufacturers and transport companies, enhancing its market reach.

Security posture

The website uses HTTPS and is hosted on a reputable CDN (AWS Cloudfront), which provides a good baseline for security. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No forms or sensitive data collection points are present on the homepage, minimizing immediate risk exposure. The lack of privacy and cookie policies indicates potential compliance gaps with GDPR and other data protection regulations. WHOIS data is unavailable, which may raise concerns about domain transparency and legitimacy. Overall, the security maturity is moderate but could be improved with better headers and compliance documentation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  2. Add security headers (CSP, HSTS, X-Frame-Options) to enhance website security and protect against common web attacks.
  3. Provide clear and accessible contact information, including emails and phone numbers, to improve business credibility and customer trust.
  4. Consider publishing WHOIS registrant information or using a trusted registrar to improve domain transparency and legitimacy.
  5. Enhance accessibility features and structured data markup to improve SEO and user experience.

Technical notes

Notes

The website is built on the Webnode CMS platform and hosted on AWS Cloudfront CDN, ensuring reliable content delivery and moderate performance. The technology stack includes JavaScript and Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and good navigation clarity. However, SEO optimization is basic, lacking structured data and comprehensive meta tags beyond Open Graph. No forms or interactive elements are present on the homepage, limiting data collection capabilities. The absence of security headers and privacy compliance features indicates areas for technical improvement to meet 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.
