High risk. 10 critical or high findings in GDPR outside view, Email security and 2 other checks.

Security score

40/100

Risk levelHigh

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

The website represents the Délégation Intergénérationnelle du Numérique, a small non-profit association within the École Normale Supérieure focused on intergenerational digital knowledge sharing and IT support for students. The site provides clear descriptive content about its mission and activities but lacks formal privacy, cookie, or terms of service policies. Technically, the site uses a simple modern CSS framework (Bulma) and is hosted by OVH, but lacks advanced security headers and visible analytics or tracking tools. The security posture is basic with no evident vulnerabilities but also no advanced protections. Overall, the domain registration is consistent with the organization's founding date and mission, supporting legitimacy. The site is safe for general audiences and does not contain any adult or questionable content.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 association operates in the education and technology sectors, targeting students at ENS with a volunteer-driven model emphasizing knowledge transfer and digital skills continuity. It occupies a niche position within the academic community, with no commercial revenue streams or advertising. The lack of contact details and formal policies suggests a small-scale operation focused on internal community support rather than public commercial engagement. The hosting by OVH and domain registration details indicate a legitimate and transparent organizational presence.

Security posture

The current security maturity is low to moderate, with no HTTPS status explicitly provided but presumed given OVH hosting. No security headers or incident response information are present, and no vulnerability disclosure or security.txt files are found. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. The site does not collect user data via forms or analytics, reducing exposure but also limiting user engagement and transparency. Recommendations include implementing HTTPS verification, adding security headers, publishing privacy and cookie policies, and establishing incident response contacts.

Recommendations

  1. Implement and enforce HTTPS with strong SSL/TLS configuration and verify certificate validity.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  4. Provide clear contact information including emails and phone numbers for support and incident response.
  5. Consider establishing a vulnerability disclosure policy and security.txt file to enhance security transparency.

Technical notes

Notes

The website uses a modern CSS framework (Bulma) for styling and is hosted by OVH, a reputable provider. The HTML structure is valid and content is well organized, but no advanced CMS or JavaScript frameworks are detected. Performance is moderate with basic mobile optimization. SEO and accessibility features are minimal but present. No analytics or tracking scripts are included, indicating a privacy-conscious approach but also limited user behavior insights. The site could benefit from improved accessibility and SEO optimizations and enhanced security configurations.
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.
