Risk levelMedium

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

Grupo Santillana de Educación Global, S.L.U. operates a comprehensive educational website offering a wide range of services including educational content publishing, teacher training, and digital platforms. The company targets educational institutions, teachers, students, and families, positioning itself as a large, international education group with a strong focus on sustainability and innovation. The website is built on WordPress with Elementor, leveraging modern web technologies and integrating cookie consent mechanisms to comply with GDPR. Security posture is moderate with HTTPS usage and consent management but lacks visible security headers and direct contact information. The absence of WHOIS data for the domain raises some concerns about domain registration transparency, though the website content and branding strongly indicate a legitimate corporate presence. Overall, the site is professional, user-friendly, and compliant with privacy regulations, but could improve in security best practices and contact transparency.

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. 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. 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

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

Santillana holds a strong market position in the education sector, offering diversified services such as evaluation systems, adult education, and language learning. The business model combines B2B and B2C approaches, serving schools and families alike. The company maintains partnerships with various regional educational platforms and job portals, enhancing its ecosystem. Growth indicators include a comprehensive sustainability report and active content updates. The website's navigation and content structure support clear communication of its offerings, though direct contact details are limited. The company appears to be a large entity based in Spain with a global footprint.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and a cookie consent mechanism aligned with GDPR. However, the lack of detected security headers such as Content Security Policy, HSTS, or X-Frame-Options suggests room for improvement. No vulnerabilities or incident response contacts were found, indicating either a low profile or limited transparency in security disclosures. The absence of WHOIS data for the domain is a notable gap, potentially impacting trust. Overall, the security maturity is moderate but would benefit from enhanced header configurations, clearer incident response channels, and improved transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Publish clear security and incident response policies with dedicated contact channels to improve transparency and readiness.
  3. Enhance accessibility features to meet international standards and improve user experience for all visitors.
  4. Provide direct company contact emails and phone numbers on the website to increase business credibility and user trust.
  5. Investigate and resolve the missing WHOIS data issue to ensure domain registration transparency and improve legitimacy perception.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Elementor page builder, integrating popular JavaScript libraries such as jQuery and OwlCarousel for UI enhancements. Google Fonts and Google Analytics are used for typography and analytics respectively. The site includes a GDPR-compliant cookie consent mechanism powered by Didomi. Performance is moderate with good mobile optimization and basic SEO practices. There is no explicit hosting provider information. Technical debt appears low, but improvements in security headers and SEO metadata completeness are recommended to reduce risks and enhance digital maturity.
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.
