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"

    • 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';…

  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

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 institution holds a significant market position in the Spanish education sector with a broad service offering from primary education to university level. Its business model focuses on academic services and education delivery, supported by a network of related domains and sub-sites. The use of multiple third-party services for analytics and marketing indicates a mature digital marketing strategy. The absence of publicly available WHOIS data is consistent with Red.es policies and does not detract from the legitimacy of the entity. The clear contact information and consistent branding reinforce trust and credibility. The institution appears to have a stable operational footprint with potential for growth in digital engagement.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and a published security policy or incident response page indicates room for improvement. The use of Cookiebot for consent management is a positive indicator of privacy awareness. The lack of a security.txt file or vulnerability disclosure mechanism suggests that the institution could enhance its security transparency and incident handling readiness. Overall, the security posture is adequate for an educational institution but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and enforce additional security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are in use.
  5. Enhance user trust by providing more detailed business and compliance information such as terms of service and data protection officer contact.

Technical notes

Notes

The website uses a modern and widely supported technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and Font Awesome for icons. Google Fonts are used for typography, enhancing visual appeal. Integration with Google Tag Manager, Google Analytics, and Facebook Pixel indicates a sophisticated approach to user analytics and marketing. Cookiebot is employed for GDPR-compliant cookie consent management. The site appears to be hosted on a platform supporting HTTPS with good SSL configuration. Performance is moderate with potential improvements in loading speed by optimizing third-party scripts. Accessibility features are present, and SEO meta tags are well implemented, supporting good search engine visibility. No CMS was explicitly detected, suggesting a custom or proprietary platform. Overall, the technical infrastructure is solid with opportunities for optimization and enhanced security controls.
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.
