42 Le Havre is a tuition-free computer programming school located in Normandy, France, operating as part of the global 42 network. The institution offers an innovative, project-based pedagogy emphasizing peer-to-peer learning and gamification, targeting a broad audience without requiring prior diplomas or coding experience. The website reflects a medium-sized educational entity founded in 2021, with a consistent brand and clear communication of its values and offerings. Technically, the site is built on WordPress with Elementor and uses modern web technologies, hosted likely behind Cloudflare DNS. Performance and mobile optimization are good, though accessibility could be improved.

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

4 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"

  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. 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

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 business operates in the education sector, focusing on free, accessible computer programming training. Its competitive advantage lies in its unique pedagogy and global network affiliation. Revenue streams are likely non-traditional, possibly relying on public funding or donations, as the education is tuition-free. The target customers are individuals seeking coding education without formal prerequisites. The partnership ecosystem includes the global 42 network and various social media platforms for outreach. Growth indicators include multiple campus locations worldwide and active event scheduling. The company maintains a strong online presence with clear navigation and relevant content.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and a cookie consent mechanism compliant with GDPR. However, it lacks visible security policies, incident response contacts, and security headers such as CSP or HSTS, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a vulnerability disclosure or security.txt file indicates room for improvement in transparency and incident management readiness. Overall, the security posture is adequate for the business type but could be enhanced to meet higher standards.

Recommendations

  1. Implement standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Publish a clear security policy and incident response plan accessible on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Conduct regular audits of third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance with WCAG standards and broaden user inclusivity.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building, supported by jQuery and AblePlayer for enhanced media accessibility. Hosting appears to be behind Cloudflare DNS, providing DNS-level security and performance benefits. The site includes Google Tag Manager and Google Analytics for tracking and marketing purposes. Performance is moderate with good mobile responsiveness and SEO optimization. Some inline styles and scripts are used for cookie management and lazy loading. There is no evidence of outdated or vulnerable libraries. Opportunities exist to improve accessibility and implement additional security headers to reduce risk.
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.
