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

ENSTA Alumni operates as a dedicated alumni association platform for ENSTA Paris graduates and students, focusing on fostering community, career support, and promoting the school's disciplines. The website presents a well-structured and content-rich environment with news, events, job offers, and networking tools, targeting its alumni audience primarily in France but with international reach. Technically, the site uses a custom CMS with a variety of modern JavaScript libraries and APIs, including mapping and analytics tools, but suffers from a critical lack of HTTPS and valid SSL certificates, which significantly impacts its security posture. Security headers and cookie consent mechanisms are implemented, indicating awareness of privacy and security best practices, though the absence of a valid SSL certificate and TLS protocols is a major vulnerability. Overall, the site is professional and trustworthy in content and design but requires urgent security improvements to protect user data and enhance trust.

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

5 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 organization positions itself as an important educational non-profit entity with a medium-sized alumni base exceeding 10,000 members across 70 countries. Its business model revolves around membership fees and providing value-added services such as career coaching, event organization, and networking opportunities. The site integrates with partner organizations and payment processors, indicating a mature ecosystem. The presence of multiple social media channels and newsletters supports engagement and growth. However, the lack of explicit terms of service and security policies may expose the organization to compliance risks. The technical infrastructure is moderately modern but requires upgrades in security and performance optimization.

Security posture

The current security posture is moderate but with critical gaps. While security headers like CSP, HSTS, XSS protection, and cookie flags are present, the absence of a valid SSL certificate and disabled TLS protocols expose the site to interception and downgrade attacks. No incident response or vulnerability disclosure policies are found, limiting transparency and preparedness. Cookie consent is implemented with a reputable tool, and forms use CSRF tokens, indicating good privacy practices. The site should prioritize obtaining and maintaining valid SSL certificates, enabling modern TLS versions, and publishing security policies to improve trust and compliance.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable TLS 1.2 or TLS 1.3 protocols and disable insecure protocols to enhance transport security.
  3. Publish clear security policies and incident response contact information to improve transparency.
  4. Regularly audit third-party scripts and dependencies to avoid vulnerable libraries and reduce attack surface.
  5. Enhance accessibility features and optimize performance to improve user experience and SEO.

Technical notes

Notes

The website is hosted on an Apache server with a custom CMS platform, likely NetAnswer. It uses a variety of JavaScript libraries including jQuery, Bootstrap, TinyMCE, Leaflet for mapping, and Google Maps API. The site loads fonts from Google Fonts and uses FontAwesome icons. Cookie consent is managed by tarteaucitron.js, and forms are protected with CSRF tokens and hCaptcha. Performance metrics are not available, but the site includes many scripts and external resources which may impact load times. The DNS setup lacks DNSSEC and CAA records, which could be improved for security. Overall, the technical infrastructure is functional but requires modernization in SSL/TLS and performance 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.
