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

The website www.cng.cz represents a professional platform operated by Internet Projekt, a.s., focused on providing information and services related to compressed natural gas (CNG) refueling stations across the Czech Republic. It serves vehicle owners and fleet operators who utilize CNG as an alternative fuel, offering detailed station locations, pricing, payment options, and route planning tools. The site demonstrates a solid market position within the energy and transportation sectors in the region. Technically, the website employs modern web technologies including Google Maps API for geolocation services, jQuery for DOM manipulation, and Cookiebot for cookie consent management. It integrates Google Tag Manager and Google Analytics for tracking and analytics purposes. The site is mobile-optimized with good design quality and navigation clarity, although some accessibility and SEO optimizations could be improved. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, which are positive indicators. However, the absence of visible security headers and lack of explicit privacy policy or terms of service pages represent areas for improvement. The WHOIS data for the domain is unavailable, which limits the ability to fully verify domain legitimacy and trustworthiness. Overall, the website is functional, professional, and serves its business purpose well, but it would benefit from enhanced transparency regarding privacy, security policies, and contact information to strengthen user trust and compliance posture.

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

      Third-party services without privacy policy

      Detected services: Google Analytics, 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025

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 business operates in the essential energy and transportation sectors, providing a network of CNG refueling stations. Its competitive advantage lies in the extensive coverage of stations with detailed operational data, facilitating user convenience. The business model revolves around retail fuel sales and infrastructure support for alternative fuel vehicles. Revenue streams likely include fuel sales and possibly partnerships with payment providers. The target customers are primarily vehicle owners and commercial fleets in the Czech Republic. The company shows signs of digital maturity through integration of mapping and analytics tools but lacks some compliance documentation. Partnerships with Google services and Cookiebot indicate a modern marketing and compliance approach.

Security posture

The security maturity level is moderate. HTTPS is enforced, and cookie consent is implemented, indicating awareness of privacy regulations. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. No incident response or security contact information is visible, which may hinder timely reporting and handling of security incidents. The absence of vulnerability disclosure or security.txt files further limits transparency. Compliance with GDPR is partially indicated by cookie consent but lacks comprehensive privacy policy documentation. The site should enhance security best practices and transparency to improve its security culture and readiness.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve transparency and compliance.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Publish clear contact information including general, support, and security incident response contacts to facilitate communication and trust.
  4. Consider adding a security.txt file and vulnerability disclosure policy to encourage responsible reporting of security issues.
  5. Regularly audit and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website uses a modern technology stack with Google Maps API for geospatial features, jQuery for scripting, and Cookiebot for cookie management. Google Tag Manager and Google Analytics are used for analytics and marketing tracking. The site is mobile responsive and has good design and navigation. However, there is no detected CMS or hosting provider information. Performance is moderate, with potential for improvement in SEO and accessibility. The site lacks some security headers and comprehensive metadata which could improve SEO and security. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
