Risk levelMedium

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

ESIEE Paris is a well-established French engineering school specializing in technological innovation, digital, energy, and environmental transitions. It holds prestigious accreditations such as CTI and CGE and offers a broad range of engineering programs including apprenticeships and international degrees. The website reflects a professional and modern educational institution with clear navigation, comprehensive content, and strong trust indicators including certifications and alumni references. Technically, the site is built on TYPO3 CMS with modern JavaScript libraries and includes robust cookie consent mechanisms ensuring GDPR compliance. Security posture is moderate with HTTPS usage and cookie management but lacks explicit security policies and visible security headers. WHOIS data is unavailable, which slightly reduces domain trust but does not detract from the overall legitimacy supported by external partnerships and certifications.

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

6 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 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. 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

The institution targets students, parents, and professional partners in the education and technology sectors. It maintains a strong market position as a top-ranked engineering school in the Île-de-France region, offering diverse programs and fostering research and industry collaboration. The business model is centered on education services, continuing education, and partnerships with companies. The presence of multiple certifications and partnerships with recognized organizations enhances its credibility and market reach. Growth indicators include active events, international programs, and a strong alumni network.

Security posture

The website demonstrates a basic to moderate security maturity level. It employs HTTPS and cookie consent tools to comply with privacy regulations. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates gaps in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. Recommendations include implementing security headers, publishing security policies, and establishing clear incident response channels to improve trust and compliance.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response information on the website.
  2. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  3. Create and maintain a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance WHOIS transparency if possible to improve domain trustworthiness.

Technical notes

Notes

The website is built on TYPO3 CMS, leveraging modern JavaScript libraries like jQuery and Swiper.js for UI components. Cookie consent is managed via Tarteaucitron.js, and analytics are performed using Matomo and Plausible, reflecting a privacy-conscious approach. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured navigation. Performance is moderate, with potential for improvement in loading speed and hosting transparency. The technical stack is modern and well-maintained, supporting a professional user experience.
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.
