Medium risk. 5 critical or high findings in GDPR outside view, Security headers and 1 other check.

Security score

Risk levelMedium

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

Linde Gas operates as a major player in the industrial gases sector, serving primarily business customers in the Czech Republic. The website provides product and service information relevant to industrial gas supply and related equipment. The technical infrastructure includes common web technologies such as jQuery, Google Tag Manager, and OneTrust for cookie consent, indicating a moderate level of digital maturity. The site is secured with HTTPS and employs standard tracking and marketing tools, but lacks explicit privacy and security policies visible on the site. Security posture is adequate but could be improved by implementing security headers and publishing incident response and vulnerability disclosure information. Overall, the site presents a legitimate business presence but would benefit from enhanced transparency and compliance documentation.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  3. 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

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 industrial and commercial customers requiring gases and related services, operating in a B2B model within the energy sector. The website content and structure suggest a large enterprise with established market presence. The absence of detailed WHOIS data limits verification of domain ownership and age, but the use of professional tracking and consent tools supports legitimacy. The business model focuses on direct sales and service provision, with no visible e-commerce or consumer-facing sales. The partnership ecosystem is not explicitly detailed on the site. Growth indicators and certifications are not prominently displayed, indicating potential areas for business development and trust enhancement.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms, which are positive security practices. However, the lack of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the content. The absence of published security policies, incident response contacts, or vulnerability disclosure programs indicates gaps in security governance and transparency. Compliance with GDPR is implied by the cookie banner but not explicitly documented. The site would benefit from publishing comprehensive security and privacy policies and implementing additional technical security controls.

Recommendations

  1. Implement and configure HTTP security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  2. Publish clear and comprehensive privacy policy and terms of service pages accessible from the website footer.
  3. Provide explicit contact information for security incidents and vulnerability disclosures, including a security.txt file.
  4. Enhance accessibility and SEO by adding structured data (JSON-LD) and improving metadata completeness.
  5. Increase transparency by displaying certifications, compliance statements, and business contact details.

Technical notes

Notes

The website uses a standard technology stack including jQuery, Bootstrap CSS, Google Tag Manager, OneTrust for cookie consent, and marketing tools like Dynamic Yield and Optimizely. The site loads external scripts from reputable CDNs and tracking services. Performance is moderate with room for optimization, especially in mobile responsiveness and accessibility. The HTML content is valid but lacks advanced SEO and accessibility features. No CMS is explicitly detected. Hosting provider details are not discernible from the content. Overall, the technical implementation is functional but could be modernized and optimized for better user experience and security.
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.
