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

Centrale Méditerranée Alumni operates as a professional alumni network for graduates and students of Centrale Méditerranée, a French engineering school. The platform offers a comprehensive suite of services including member directories, event calendars, job boards, and news updates, fostering community engagement and career development. The website is well-branded and targets alumni, students, and recruiters within the educational sector in France. Technically, the site leverages modern web technologies such as Vue.js, Google Analytics, and Google Maps API, ensuring a responsive and interactive user experience. The presence of OAuth-based single sign-on options enhances user convenience and security. The site demonstrates good mobile optimization and SEO practices, although some accessibility features could be improved. From a security perspective, the website enforces HTTPS and uses secure login forms. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident, and no vulnerability disclosure or security.txt files are published. Privacy compliance is strong with visible privacy and cookie policies aligned with GDPR requirements. Overall, the website presents a trustworthy and professional online presence for the alumni community, with moderate technical sophistication and a solid security posture. Recommendations include enhancing security headers, publishing vulnerability disclosure information, and continuing to monitor third-party scripts for vulnerabilities.

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

7 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Cloudflare, Google APIs

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

  2. 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 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';…

  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 alumni network holds a solid position within the French educational sector, serving a medium-sized community of over 17,000 members. Its business model revolves around membership engagement, event organization, and career support services. The network benefits from partnerships with merchandise stores, career platforms, and the official school foundation, enhancing its value proposition. The integration of social media channels and active content updates indicate a dynamic and growing community. The absence of public WHOIS data suggests privacy protection, which is typical for non-profit organizations. The platform's focus on professional networking and career advancement aligns well with its target audience of alumni and recruiters.

Security posture

The website demonstrates a baseline security maturity with HTTPS enforcement and secure authentication mechanisms including OAuth providers. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No public vulnerability disclosure or incident response contacts are found, which could hinder timely reporting and remediation of security issues. The use of multiple third-party scripts necessitates ongoing security audits to mitigate risks. Overall, the security posture is adequate for the site's purpose but could be strengthened by adopting additional best practices and transparency measures.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  2. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Maintain and clearly communicate data retention and privacy policies to reinforce GDPR compliance.

Technical notes

Notes

The website is built on a modern tech stack featuring Vue.js for frontend interactivity, Google Analytics and Tag Manager for tracking, and Google Maps API for geolocation features. The CMS appears to be a specialized alumni framework (AF Connect). Performance is moderate with good mobile responsiveness and SEO optimization. Some legacy technologies like YUI are still present, which may indicate technical debt. The site uses asynchronous script loading and caching mechanisms to optimize load times. Opportunities exist to modernize certain components and enhance accessibility compliance to reduce technical risks and improve 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.
