42 Madrid is a pioneering free programming campus located in Madrid, Spain, supported by Fundación Telefónica. It offers a unique peer-to-peer, gamified learning experience accessible 24/7, targeting individuals over 18 years old without requiring prior qualifications. The campus aims to equip students with hard and soft digital skills demanded by the labor market through a disruptive educational model. Technically, the website is built on WordPress with modern libraries such as jQuery, Flickity, and Bootstrap, and integrates Google reCAPTCHA for form security. Privacy and cookie policies are comprehensive and GDPR compliant, with clear consent mechanisms. Security posture is solid with HTTPS and secure form handling, though some security headers and incident response information are missing. The domain WHOIS data is unavailable, which raises some concerns about domain legitimacy, but the strong association with Fundación Telefónica and consistent branding mitigate this risk.

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 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: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Google APIs

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

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

42 Madrid operates as a non-profit educational entity within the technology and education sectors, leveraging Fundación Telefónica's support. Its business model focuses on free, innovative programming education with open enrollment and a gamified peer-to-peer methodology. The campus network includes sister sites in Urduliz, Barcelona, Málaga, and Sao Paulo, indicating a growing ecosystem. The target audience is young adults seeking flexible, high-quality digital skills training. The website's content quality, social media integration, and trust signals position 42 Madrid as a leading player in disruptive digital education in Spain. Revenue streams likely come from Fundación Telefónica and partnerships rather than direct tuition fees. Strategic partnerships and certifications enhance credibility and market reach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, integration of Google reCAPTCHA to prevent automated abuse, and a cookie consent mechanism aligned with GDPR. However, the absence of explicit security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security hardening. No incident response or security policy information is publicly available, which could hinder rapid response to security incidents. No vulnerabilities or exposed sensitive data were detected in the analysis. The missing WHOIS data is a concern for domain trust but does not directly impact website security. Overall, the security posture is good but could be improved by adding security headers and incident response transparency.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  3. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  4. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on WordPress 6.7.2, utilizing jQuery, Flickity for carousels, Bootstrap for responsive design, and Google reCAPTCHA v3 for spam protection. The site loads external fonts from Google Fonts and uses CDN-hosted scripts for performance. The design is mobile-optimized with responsive navigation and multimedia content. Performance is moderate with room for optimization. SEO is supported by proper meta tags and canonical links. Accessibility is basic but could be improved. The site uses a cookie consent plugin with detailed user preference management. Hosting provider details are not explicitly found. Overall, the technical infrastructure is modern and stable, 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.
