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

Owens Corning is a leading global manufacturer specializing in roofing, insulation, composite materials, and doors. The company serves building professionals, contractors, and consumers with a broad portfolio of building and remodeling solutions. Their market position is strong, supported by comprehensive corporate governance, sustainability initiatives, and investor relations transparency. The website reflects a mature enterprise with consistent branding and professional content. Technically, the website employs modern web technologies including React, Adobe DTM for tag management, and Osano for consent management, indicating a high level of digital maturity. The site is mobile optimized, accessible, and SEO-friendly, with good performance metrics. Analytics and marketing tools are used responsibly with visible cookie consent mechanisms. From a security perspective, the site enforces HTTPS and uses cookie consent banners to comply with privacy regulations. While explicit security headers are not fully visible in the HTML, no vulnerabilities or exposed sensitive data were detected. The absence of a public security policy or vulnerability disclosure page is noted as an area for improvement. Overall, the website presents a low risk profile with strong business credibility and privacy compliance. The lack of WHOIS data slightly reduces trust but is mitigated by the professional presentation and extensive corporate information. Strategic recommendations include enhancing security header implementation, publishing a security policy, and establishing a vulnerability disclosure process.

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. 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

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. 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

    • 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

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

Owens Corning operates in the manufacturing sector, focusing on building materials and composites. Their business model revolves around product innovation, sustainability, and global distribution. The company targets professional builders and remodelers as well as end consumers. Their investor relations and sustainability reporting indicate a commitment to transparency and long-term growth. The presence of multiple regional career portals suggests a global footprint. Partnerships with specialized domains for news, investors, and careers support a robust ecosystem. The company leverages digital marketing and analytics tools to optimize customer engagement and brand presence.

Security posture

The website demonstrates a solid security posture with enforced HTTPS and cookie consent management, aligning with GDPR requirements. No critical vulnerabilities or exposed sensitive information were found. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options is a minor gap. The absence of a public security policy or incident response contact limits transparency in security governance. No vulnerability disclosure or security.txt file was detected, which could improve community trust and incident handling. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and enforce comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance transparency around data retention policies and user privacy practices.

Technical notes

Notes

The website uses a modern technology stack with React for frontend rendering and Adobe DTM for tag management, indicating a sophisticated digital infrastructure. Osano is used for cookie consent and privacy compliance, reflecting adherence to regulatory requirements. The site loads fonts and icons efficiently and integrates marketing tools like Curalate. Performance is moderate with good mobile optimization and accessibility features. The CMS is not explicitly identified but appears custom or proprietary. There is an opportunity to improve technical SEO by adding structured data and enhancing security headers. Hosting provider details are not disclosed in the HTML.
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.
