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

Messer France SAS operates as a key supplier of industrial, food-grade, special, and medical gases within France, serving a broad range of industrial and commercial clients. The company is part of the larger Messer Group, a recognized entity in the energy sector. Their website reflects a mature digital presence with comprehensive product and service offerings, targeting B2B customers in various sectors including medical, food, and industrial gases. The site is professionally designed, mobile-optimized, and includes essential compliance and privacy information, indicating a commitment to regulatory adherence and user experience. Technically, the website leverages the Liferay CMS platform, integrating modern JavaScript libraries such as jQuery, Bootstrap, and HubSpot marketing and analytics tools. The infrastructure supports good performance and accessibility standards, with HTTPS enforced and security headers present, contributing to a solid security posture. However, the absence of explicit security policies and incident response information suggests areas for improvement in transparency and readiness. From a security perspective, the site demonstrates good practices including cookie consent mechanisms and no visible vulnerabilities or exposed sensitive data. The lack of WHOIS data limits domain registration trust analysis, but the professional nature of the site and its content supports legitimacy. Overall, the risk profile is moderate with recommendations to enhance security disclosures and domain registration transparency. Strategically, Messer France should focus on publishing clear security policies, incident response contacts, and vulnerability disclosure information to strengthen trust and compliance. Regular audits of third-party scripts and continuous monitoring will further enhance security posture. The company’s digital maturity is solid, supporting its market position and business objectives effectively.

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.

Priority findings

6 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

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

Messer France is positioned as a significant player in the French industrial gases market, leveraging the global Messer Group brand. Their business model focuses on supplying a wide range of gases and related services to industrial, medical, and food sectors. The company benefits from a strong partnership ecosystem within the Messer Group, including sister sites and related brands. Their digital presence supports customer engagement through e-services, mobile applications, and comprehensive product information. Growth indicators include active content updates, social media engagement, and sustainability reporting. The company’s operations reflect a mature B2B approach with emphasis on compliance and customer service.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, presence of key security headers, and cookie consent mechanisms. No exposed sensitive information or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in transparency and preparedness. Compliance with GDPR is evident through privacy policies and cookie management. The site uses third-party marketing and analytics scripts which should be regularly audited to mitigate supply chain risks. Overall, the security posture is solid but could be improved by publishing explicit security governance documents and incident response details.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact information to facilitate vulnerability reporting.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Regularly audit and update third-party scripts to reduce supply chain risks.
  5. Enhance domain registration transparency by ensuring WHOIS data is available and accurate.

Technical notes

Notes

The website is built on the Liferay CMS platform, utilizing modern web technologies including jQuery, Bootstrap, and Chart.js for interactive content. HubSpot scripts are integrated for marketing automation and analytics. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate with combined CSS and JS resources loaded efficiently. No broken elements or errors were detected in the HTML content. The use of CDN-hosted resources and Google Fonts contributes to a smooth user experience. Opportunities exist to improve technical SEO by adding structured data and enhancing metadata completeness.
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.
