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

Saint-Gobain Glass is a major player in the manufacturing sector specializing in glass products, operating as part of the global Saint-Gobain group. The company targets industrial clients and construction sectors with a B2B business model. The website is currently inaccessible due to a Cloudflare security challenge, limiting direct content analysis. The domain registration data supports the legitimacy and long-standing presence of the company in the market. The technical infrastructure includes modern analytics tools like Google Tag Manager and Google Analytics 4, hosted behind Cloudflare for security and performance. However, the lack of visible privacy policies, contact information, and security headers on the landing page indicates areas for improvement in transparency and compliance. Overall, the website's security posture is difficult to assess fully due to access restrictions, but domain data and hosting choices suggest a mature enterprise environment.

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

10 findings rated critical or high. Fix these first.

  1. 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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: mx3.linkbymail.fr

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)

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 holds a strong market position as a large enterprise in manufacturing, with a global footprint evidenced by multiple regional domains. Its business model focuses on supplying glass solutions to industrial and construction clients. The partnership ecosystem includes related Saint-Gobain group domains and associated brands. The absence of visible business contact details or policies on the landing page may impact customer trust and engagement. Growth indicators and revenue streams are not directly observable from the website content due to access limitations.

Security posture

The website is protected by Cloudflare's WAF, which provides a robust security layer against common web threats. However, the challenge page blocks content access, preventing full security header and SSL configuration analysis. No explicit security policies or incident response contacts are published on the accessible content. The domain WHOIS data shows good domain security practices with prohibitive status flags. The use of Google Tag Manager and Analytics indicates data collection but lacks visible privacy compliance mechanisms. Overall, the security posture is moderate but could benefit from enhanced transparency and policy publication.

Recommendations

  1. Publish clear and accessible privacy and cookie policies to improve GDPR compliance and user trust.
  2. Expose security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance security posture.
  3. Enable DNSSEC on the domain to strengthen DNS security.
  4. Provide visible contact information including security incident response channels to improve transparency and readiness.
  5. Optimize website accessibility and mobile responsiveness once the WAF challenge is resolved to improve user experience.

Technical notes

Notes

The website uses modern JavaScript-based analytics tools and is hosted behind Cloudflare, indicating a focus on security and performance. However, the current Cloudflare challenge page prevents content delivery, resulting in poor content quality and user experience scores. No CMS or specific frameworks are detected from the available data. The technical implementation lacks visible SEO and accessibility features on the challenge page. The domain is well-established and uses a reputable registrar, supporting a stable technical foundation. Future improvements should focus on resolving access issues and enhancing front-end content delivery.
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.
