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

The website www.nafion.com represents the Nafion™ brand, a product line of The Chemours Company specializing in membranes, dispersions, and resins primarily serving the chemical, chlor-alkali, energy, and transportation industries. The site positions Nafion™ as a leading provider with over 50 years of experience, offering advanced materials that improve process efficiency and support emerging clean energy applications. The business model is B2B, targeting industrial manufacturers and energy sector clients. The website is professionally designed, mobile-optimized, and rich in relevant content, including white papers and industry applications, reinforcing its market position. Technically, the site employs modern web technologies including Google Tag Manager, Microsoft Application Insights for analytics, and cookie consent management via CookieLaw.org. The site is hosted securely with HTTPS and shows good SEO and accessibility practices. However, explicit security headers are not detected, and no dedicated security policy or incident response information is published, indicating room for improvement in security transparency. From a security perspective, the site demonstrates a solid baseline with encrypted connections and no visible vulnerabilities or exposed sensitive data. The absence of WHOIS registration data for the domain www.nafion.com raises concerns about domain legitimacy or possible use of subdomains or aliases under the Chemours corporate umbrella. This discrepancy impacts trustworthiness and business credibility scores. No direct company contact emails or phone numbers are published, with contact facilitated via forms only. Overall, the website is a high-quality, professional resource for industry stakeholders but would benefit from enhanced security disclosures, domain registration transparency, and direct contact information to improve trust and compliance posture.

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

7 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. 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

  3. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

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

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 Chemours Company leverages the Nafion™ brand to maintain a strong foothold in the specialty chemical materials market, focusing on membranes and resins for energy and transportation sectors. The company benefits from a well-established reputation and a broad portfolio of products that address evolving market demands such as clean energy and hydrogen production. The website supports this positioning with detailed product and application information, white papers, and global language support. The lack of direct contact details and missing WHOIS data suggest a controlled corporate web presence rather than a standalone entity, which aligns with a large enterprise operating multiple brands. The partnership ecosystem includes Chemours corporate sites and social media channels, enhancing brand reach and customer engagement.

Security posture

The website maintains a secure HTTPS environment and employs reputable analytics and consent management tools, indicating a commitment to user privacy and data protection. However, the absence of key security headers (e.g., Content Security Policy, HSTS) and lack of published security policies or incident response contacts reveal gaps in security maturity and transparency. No vulnerability disclosures or security.txt files are present, limiting external security collaboration. The missing WHOIS data for the domain introduces uncertainty about domain ownership and registration legitimacy, which could pose risks if not aligned with corporate governance. Overall, the security posture is moderate with opportunities for strengthening compliance and incident readiness.

Recommendations

  1. Publish explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance browser security.
  2. Provide a publicly accessible security policy and incident response contact information to improve transparency and trust.
  3. Register and maintain accurate WHOIS information for the domain to ensure domain legitimacy and reduce suspicion.
  4. Consider adding a security.txt file or vulnerability disclosure program to encourage responsible reporting of security issues.
  5. Enhance direct contact information availability, including verified company emails and phone numbers, to improve business credibility.

Technical notes

Notes

The website uses a modern technology stack with asynchronous loading of analytics and consent scripts, improving performance and user experience. The presence of Foundation CSS framework and FontAwesome icons supports responsive and accessible design. The site is hosted on a platform likely managed by Chemours with CDN and security integrations. Performance is moderate with good mobile optimization and SEO practices. There is no detected CMS, suggesting a custom or enterprise-managed platform. Technical risks include missing security headers and incomplete domain registration data, which could affect long-term operational security and trust.
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.
