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

Messer SE & Co. KGaA is a leading privately owned specialist in industrial, medical, and specialty gases with a global presence across Asia, Europe, and the Americas. The company operates a professional career site powered by the Teamtailor platform, offering a wide range of job opportunities and showcasing its culture and values. The website reflects a mature digital presence with strong branding and comprehensive content aimed at attracting potential employees. Technically, the site leverages modern JavaScript frameworks and is hosted on Teamtailor's AWS-backed CDN infrastructure, ensuring fast performance and excellent mobile optimization. The use of cookie consent mechanisms and privacy policies indicates good privacy compliance, although explicit security headers and incident response information are not publicly disclosed. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data, but could improve by publishing security policies and providing clear channels for incident reporting. The absence of WHOIS data for the subdomain is typical and does not detract from the site's legitimacy, which is supported by consistent branding and multiple regional subsidiary links. Overall, the site presents a low-risk profile with strong business credibility and technical implementation, suitable for its purpose as a corporate career portal.

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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Messer holds a strong market position as the largest privately owned industrial gases specialist, with a business model focused on providing gases and related services globally. Revenue streams are primarily from industrial, medical, and specialty gases sales. The career site targets job seekers worldwide, reflecting growth and investment in talent acquisition. The company maintains a diverse geographic footprint with multiple subsidiaries, enhancing market reach and operational resilience. Strategic partnerships with Teamtailor for digital recruitment indicate a modern approach to HR and employer branding.

Security posture

The website demonstrates a good security posture with HTTPS enforced and no visible sensitive data leaks. Cookie consent and privacy policies align with GDPR requirements, indicating compliance awareness. However, the lack of explicit security headers (e.g., CSP, HSTS) and absence of published security policies or incident response contacts suggest areas for improvement. No vulnerabilities or suspicious activities were detected in the content. The security score is solid but could be enhanced by adopting best practices in header configuration and transparency.

Recommendations

  1. Implement and publish comprehensive security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Provide a dedicated security policy page and clear incident response contact information to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance data protection officer visibility and contact details to strengthen GDPR compliance signals.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The site is built on a modern tech stack including JavaScript, StimulusJS, and Font Awesome 6 icons, hosted on Teamtailor's AWS CDN infrastructure. It features responsive design with excellent mobile optimization and accessibility considerations. Performance is fast with preloading of images and videos. SEO is supported by proper meta tags and Open Graph data. The use of Teamtailor as a CMS and recruitment platform streamlines job management but limits direct control over some technical aspects. Overall, the technical implementation is robust and well-suited for a corporate career site.
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.
