Risk levelLow

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

Messer North America, Inc is a leading supplier of industrial, medical, specialty, and laser gases in the United States and Americas region. The company operates as part of the largest global privately held industrial gases group, offering a broad portfolio of gases and technical solutions tailored to diverse industries including healthcare, manufacturing, aerospace, and environmental sectors. Their website reflects a mature digital presence built on the HubSpot CMS platform, featuring comprehensive product and market information, customer testimonials, and strong branding consistency. Privacy and cookie policies are well implemented with user consent mechanisms, supporting compliance with GDPR and related regulations. However, the absence of publicly available WHOIS data and lack of explicit security policy or incident response information slightly reduce trustworthiness from a security perspective. Overall, the site demonstrates a solid security posture with HTTPS enforcement and no visible vulnerabilities, but could improve transparency around security governance and incident handling.

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

3 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.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 256-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
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 holds a strong market position as a major industrial and medical gas supplier with a broad customer base across multiple sectors. Their business model focuses on B2B supply and technical services, leveraging global expertise and local agility. The company’s digital ecosystem includes multiple regional sites and extensive resource libraries, indicating a strategic emphasis on customer education and support. The presence of certifications such as Great Place to Work enhances employer branding and trust. Marketing and analytics tools like Google Tag Manager and Facebook Pixel are used responsibly with cookie consent. The company’s partnership with Messer Americas and related domains suggests a well-integrated corporate structure. Growth indicators include active content updates and engagement with sustainability and safety topics.

Security posture

The website enforces HTTPS and uses modern security best practices such as cookie consent banners and no exposure of sensitive data in the HTML. However, the lack of security headers (e.g., CSP, X-Frame-Options) and absence of a public security policy or incident response contact reduce the overall security maturity. No vulnerability disclosure or security.txt file was found, which is a missed opportunity for transparency and community engagement. The WHOIS data is missing or privacy protected, which is unusual and may warrant further investigation. Overall, the security posture is good but could be enhanced by publishing explicit security governance documents and improving HTTP header configurations.

Recommendations

  1. Publish a dedicated security policy and incident response page with clear contact channels.
  2. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing HubSpot’s marketing and analytics tools including CTAs, tracking pixels, and Google Tag Manager. The tech stack includes jQuery 1.7.1, which is outdated and may pose security risks; updating to a modern version is recommended. Performance is moderate with good mobile optimization and SEO practices. The site uses structured data (JSON-LD) for organization info, enhancing search engine understanding. Hosting is managed by HubSpot, providing reliable uptime and SSL certificates. Opportunities exist to improve accessibility and implement modern JavaScript frameworks or libraries for enhanced interactivity and maintainability.
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.
