Risk levelLow

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

Trinseo is a specialty material solutions provider focused on partnering with companies to deliver innovative and high-quality materials. The website presents a professional and well-structured digital presence built on Drupal 10, incorporating modern compliance tools such as Cookiebot for GDPR and cookie consent management. The technical infrastructure includes Google Tag Manager and bot detection scripts, indicating a mature digital setup. Security posture is solid with HTTPS enforced and consent mechanisms in place, though explicit security headers and incident response contacts are absent. The lack of WHOIS registration data is a notable anomaly that slightly reduces trust but does not overshadow the overall legitimacy indicated by the website content and compliance features. Strategic recommendations include enhancing security headers, publishing security policies, and improving transparency with contact information for security incidents.

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

1 finding 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.

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

Trinseo operates in the manufacturing sector, specializing in specialty materials and innovation partnerships. The business model is B2B, targeting industrial and commercial companies requiring advanced material solutions. The website content and cookie declarations suggest a large enterprise with a global footprint, though no explicit country or founding year is stated. The partnership with domains like ulprospector.com indicates integration with industry-specific platforms. The company demonstrates strong compliance with privacy regulations and uses advanced marketing and analytics tools to engage its audience. However, the absence of visible contact details and WHOIS data suggests areas for improvement in transparency and trust-building.

Security posture

The website enforces HTTPS and uses Cookiebot for cookie consent, reflecting good privacy compliance. Bot detection scripts are deployed to mitigate spam and automated threats. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No vulnerability disclosures or security.txt files are present, and no explicit incident response contacts are provided. These gaps could impact incident handling and user trust. Overall, the security posture is good but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a dedicated security policy and provide clear incident response contact information.
  3. Establish a vulnerability disclosure program and consider publishing a security.txt file.
  4. Add explicit company contact information including emails and phone numbers on the website.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, ensuring a solid foundation for content management and security updates. Integration with Google Tag Manager and Cookiebot indicates a focus on analytics and privacy compliance. The presence of CleanTalk bot detection enhances security against automated threats. Performance is moderate, with good mobile optimization and accessibility features observed. SEO is well addressed through meta tags and Open Graph data. However, the hosting provider is not explicitly identified, and no advanced performance optimization techniques are evident. Overall, the technical infrastructure supports a professional and compliant web presence with room for further optimization.
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.
