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

Dassault Systèmes is a global leader in 3D design, engineering, and simulation software, providing virtual twin technologies and collaborative platforms that empower businesses to innovate sustainably. The company targets professional and enterprise customers in technology and manufacturing sectors, offering a comprehensive suite of software solutions including SolidWorks, SIMULIA, DELMIA, and ENOVIA. The website reflects a mature digital presence with excellent content quality, professional design, and clear navigation, supporting its enterprise stature. Technically, the website employs modern web technologies such as Vue.js, Tailwind CSS, and advanced analytics tools like Google Analytics and Crazy Egg. It demonstrates good performance, mobile optimization, and accessibility features. Security posture is strong with HTTPS enforcement, security headers, and secure service endpoints, although explicit public security policies and incident response information are limited. The absence of WHOIS data for the domain www.3ds.com is a notable anomaly, reducing domain registration transparency and trust slightly. However, the overall business credibility, professional branding, and comprehensive privacy and cookie policies mitigate this concern. No suspicious or malicious content was detected, and the site is safe for general audiences. Strategically, Dassault Systèmes should consider publishing detailed security policies and vulnerability disclosure information to enhance transparency and trust. Continued investment in privacy compliance and user data protection will support regulatory adherence and customer confidence.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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

Dassault Systèmes holds a strong market position as a pioneer in 3D design and simulation software, serving a global enterprise customer base. Its business model revolves around software licensing, platform services, and innovation enablement. The company benefits from a diversified portfolio of subsidiaries and brands, enabling cross-selling and integrated solutions. Growth is driven by digital transformation trends and demand for virtual twin technologies. The company maintains a robust partnership ecosystem and invests in compliance and certifications such as ISO 27001. Its website content and structure reflect a focus on professional audiences and enterprise solutions, supporting lead generation and brand authority.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. GDPR compliance is well addressed through privacy and cookie policies with consent mechanisms. The security score is high but could be enhanced by publishing explicit security governance documents and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page detailing security governance and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Enhance transparency around data protection officer and privacy contacts.
  5. Maintain and update WHOIS registration data to improve domain trustworthiness.

Technical notes

Notes

The website is built on a modern technology stack including Vue.js and Tailwind CSS, ensuring responsive and performant user experience. It leverages Google Tag Manager and Crazy Egg for analytics and user behavior tracking. The site is well optimized for mobile devices and accessibility standards. The use of structured data (JSON-LD) improves SEO and search engine understanding. Hosting details are not explicit but the site uses CDN and tracking domains for performance and analytics. Overall, the technical infrastructure supports a robust and scalable digital presence with minimal technical debt.
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.
