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

The website nastavsitlak.cz is a Czech-language application designed to assist professionals in correctly setting the pressure of driving gas (Biogon®) used in beverage dispensing systems. It is branded under Linde Gas a.s., a well-known industrial gases supplier, indicating a strong business presence in the energy sector. The site provides interactive sliders for input parameters and displays calculated pressure values, targeting business users involved in beverage dispensing operations. Technically, the site uses a modern but basic tech stack including jQuery, Bootstrap, and Google Analytics for tracking. The site is mobile optimized and has basic SEO and accessibility features. Privacy and cookie policies are present and implemented with OneTrust consent mechanisms, reflecting compliance with GDPR requirements. However, no contact information or terms of service pages are provided, limiting direct user engagement and transparency. From a security perspective, the site uses HTTPS and cookie consent but lacks visible security headers and explicit security policies. The absence of WHOIS data for the domain reduces trustworthiness from a domain registration perspective, though the website content and branding strongly suggest legitimate business use. No critical vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website is functional and professional for its niche purpose but would benefit from enhanced security headers, clearer contact information, and domain registration transparency to improve 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

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

Linde Gas a.s. operates in the energy sector, providing industrial gases and related services. This website represents a specialized tool supporting their beverage dispensing product line, indicating a B2B business model focused on operational support. The company leverages its established brand to provide value-added digital services. The lack of direct contact details on this site suggests it is a supplementary tool rather than a primary customer interface. The presence of privacy and cookie policies aligns with regulatory compliance, while the use of Google Analytics indicates data-driven marketing and user behavior analysis. The site’s market positioning is consistent with a large, established energy company offering niche technical solutions to professional clients.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent implemented via OneTrust. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces its defense-in-depth. No forms or user input fields are present, minimizing attack surface. The missing WHOIS data is a concern for domain legitimacy verification. No incident response or security policy information is provided, indicating limited transparency in security governance. Overall, the site is low risk but could improve by adding security headers, publishing security policies, and providing contact channels for security incidents.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add explicit business contact details to improve transparency and user trust.
  4. Investigate and resolve the missing WHOIS data to enhance domain legitimacy and trust.
  5. Enhance accessibility features to meet higher standards and improve user experience.

Technical notes

Notes

The website uses a classic web technology stack with jQuery and Bootstrap for UI components and Google Analytics for tracking. The site is responsive and mobile-friendly with basic SEO meta tags. No CMS or advanced frameworks detected, indicating a custom or lightweight implementation. Performance is moderate with asynchronous loading of analytics scripts. The site lacks advanced accessibility features and security headers. Hosting provider and SSL certificate details are not provided, limiting full technical assessment. Overall, the technical implementation is solid for a niche application but could benefit from modernization and enhanced security controls.
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.
