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

ENSTA Paris is a prestigious French engineering school and a founding member of the Institut Polytechnique de Paris. It offers a wide range of engineering education programs including engineering cycles, masters, specialized masters, doctoral studies, and executive education. The institution focuses on sectors such as transport, energy, defense, robotics, and artificial intelligence, positioning itself as a key player in education and research within these domains. The website reflects a strong brand presence with comprehensive content and clear navigation, targeting prospective students, researchers, and industry partners. Technically, the site is built on Drupal 9 and uses Apache with mod_pagespeed for optimization, but lacks HTTPS which is a critical security shortfall. Matomo analytics is used for user tracking, indicating a moderate level of user data collection with reasonable privacy compliance. Security posture is weak due to the absence of SSL/TLS encryption and missing security headers, exposing the site to potential risks. Business credibility is supported by multiple certifications and trust labels, but contact information is not prominently displayed, which could impact user trust and engagement. Overall, the site is content-rich and professionally designed but requires urgent security improvements to protect users and data.

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.

Business context

Business profile

ENSTA Paris operates as an essential educational entity within the French higher education landscape, serving a medium-sized student body with over 1200 students and a significant number of permanent researchers and faculty. Its market position is strong due to its historical legacy and membership in the Institut Polytechnique de Paris. The business model centers on delivering high-quality engineering education and research outputs, supported by partnerships with industry and international collaborations. The institution leverages certifications such as ISO 21001 and ISO 9001 to demonstrate quality management and educational excellence. Its digital presence supports recruitment, alumni relations, and corporate partnerships. The lack of visible direct contact details on the homepage suggests a focus on structured navigation to dedicated contact pages. The partnership ecosystem includes alumni networks, research labs, and international programs like Erasmus+. Strategic growth is indicated by the recent merger with ENSTA Bretagne and active innovation initiatives.

Security posture

The current security posture of the ENSTA Paris website is suboptimal. The absence of a valid SSL/TLS certificate means the site is served over unencrypted HTTP, exposing visitors to risks such as data interception and man-in-the-middle attacks. No HSTS policy is implemented to enforce HTTPS usage. Security headers are minimal, with only x-content-type-options present, and no Content-Security-Policy or Referrer-Policy headers detected. The site does not implement OCSP stapling or session resumption mechanisms, which could improve TLS performance and security. No vulnerability disclosure or incident response policies are publicly available, limiting transparency and preparedness. While no known SSL vulnerabilities like Heartbleed or POODLE are detected, the lack of HTTPS is a critical issue that significantly lowers the security score. The site uses Drupal 9, which is a modern CMS, but the security benefits are undermined by missing HTTPS. Overall, the site requires immediate remediation to enable HTTPS and enhance security headers to protect users and data integrity.

Recommendations

  1. Install and configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Add comprehensive security headers including Content-Security-Policy, Referrer-Policy, and X-Frame-Options.
  4. Deploy OCSP stapling and enable TLS session resumption to improve security and performance.
  5. Introduce a cookie consent mechanism to comply with privacy regulations and enhance user trust.
  6. Make contact information (email, phone) more visible on the homepage or accessible pages.
  7. Publish a vulnerability disclosure policy and incident response contact details to improve transparency.
  8. Regularly audit and update Drupal and all dependencies to mitigate vulnerabilities.
  9. Enhance accessibility features to improve compliance and user experience for all visitors.
  10. Continue leveraging certifications and trust labels prominently to reinforce credibility.
Technical notes

Notes

The website is built on Drupal 9 CMS running on an Apache server with mod_pagespeed enabled for performance optimization. It uses Google Fonts for typography and integrates Matomo analytics for user tracking. The site is served over HTTP without SSL/TLS, which is a significant technical deficiency. The DNS setup includes custom authoritative name servers and a valid SPF record for email protection. The site has a complex and well-structured navigation menu with multiple levels, supporting a rich content hierarchy. Performance metrics indicate no load time or resource data available, but mod_pagespeed suggests some optimization efforts. Mobile optimization is good with responsive design and viewport meta tags. Accessibility is basic with skip links and language attributes but no explicit ARIA roles or advanced features detected. SEO is supported by canonical links, meta descriptions, keywords, and language tags. The technical stack is modern but requires urgent security upgrades to HTTPS and enhanced header configurations to reduce risk and improve 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.
