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

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 holds a strong market position in the Czech Republic's GPS tracking industry, leveraging decades of experience and a broad client portfolio. Their business model combines hardware sales (GPS units) with software services (monitoring platforms and mobile apps), targeting sectors like personal vehicles, logistics, construction machinery, and municipal equipment. Partnerships with NAM system and 1box.cz indicate a collaborative ecosystem enhancing service offerings. The website content and references suggest a focus on B2B clients with some B2C elements. Growth indicators include continuous product updates (e.g., 4G support) and active participation in industry events. The company maintains a consistent brand image and trust signals through certifications and client testimonials.

Security posture

The website demonstrates a good security baseline with enforced HTTPS, multiple security headers, and use of Google reCAPTCHA on forms to mitigate spam and abuse. However, the lack of a visible cookie consent mechanism and absence of publicly available security policies or incident response plans represent compliance and transparency gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of multiple third-party scripts necessitates ongoing monitoring to prevent supply chain risks. The missing WHOIS data is a minor concern but does not directly impact the website's operational security. Overall, the security posture is adequate but could be enhanced by formalizing policies and improving user privacy controls.

Recommendations

  1. Implement a clear and visible cookie consent banner to comply fully with GDPR and ePrivacy regulations.
  2. Publish a comprehensive security policy and incident response plan accessible to users and partners.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential security risks.

Technical notes

Notes

The website is powered by WordPress CMS with a suite of well-known plugins such as Yoast SEO for search optimization, Contact Form 7 for form handling, and Slider Revolution for visual content. It integrates multiple analytics and marketing tools including Google Analytics, Google Tag Manager, Facebook Pixel, and Smart Emailing, reflecting a mature digital marketing strategy. The site is mobile-optimized with responsive design and lazy loading for images, contributing to moderate performance. Accessibility is basic but could be improved. The technical stack is modern and widely supported, though reliance on multiple external scripts requires vigilant security management. Hosting details are not explicitly identified, but the presence of Czech language and local contact info suggests regional hosting or CDN usage.
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.
