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

8 findings rated critical or high. Fix these first.

  1. 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

  2. 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';…

  3. 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

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 educational publishing sector in Brazil, focusing on Spanish language education. Its business model revolves around content publishing and digital distribution through portals and catalogs. The company targets students, educators, and educational institutions, providing comprehensive learning materials aligned with educational standards like BNCC. Partnerships with Moderna and Richmond enhance its ecosystem and reach. The presence of accessible content and digital portals indicates a focus on modern educational delivery methods. The company appears to be large and established, with a professional online presence but could improve transparency by publishing privacy and security policies.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism implemented via OneTrust. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth posture. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses standard third-party analytics and tracking scripts, which require careful privacy management. There is no visible incident response or vulnerability disclosure information, which could be improved to enhance trust and compliance. Overall, the security posture is adequate but could benefit from enhanced security headers and published security policies.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security.
  3. Provide clear contact information including company emails and phone numbers for support and security incidents.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly update JavaScript libraries and monitor third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a custom CMS platform called Lumis Portal and uses legacy jQuery 1.6.2 along with jQuery UI and other JavaScript libraries. It integrates Google Tag Manager, Google Analytics, and Facebook SDK for analytics and tracking. Hosting is professional with AWS DNS servers. The site has basic mobile optimization and accessibility features, including an accessibility toolbar with contrast and zoom controls. Performance is moderate, with some potential for improvement by modernizing the tech stack and optimizing assets. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced SEO and security practices.
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.
