Risk levelMedium

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

Sanoma Learning is a prominent European K12 education company providing a broad range of printed and digital learning content and platforms to support teachers and schools. The company is part of the larger Sanoma Group, with multiple subsidiaries across Europe. The website reflects a mature digital presence with professional design, clear navigation, and relevant educational content targeting educators and institutions. Technically, the site uses modern JavaScript libraries, Microsoft Application Insights for telemetry, and Adobe DTM for tag management, indicating a well-instrumented digital infrastructure. Security posture is adequate with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and published security policies are lacking. The absence of WHOIS data is a notable anomaly, potentially impacting domain trustworthiness. Overall, the website is professional, content-rich, and trustworthy from a business perspective but could improve transparency in privacy and security disclosures.

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

2 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 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 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

Sanoma Learning holds a leading position in the European K12 education market, offering a comprehensive portfolio of learning solutions including content, digital platforms, and analytics. Their business model focuses on enabling teachers and schools to improve learning outcomes through innovative products. The company benefits from being part of the Sanoma Group, leveraging a strong brand and extensive market reach. The presence of multiple subsidiaries indicates a diversified portfolio and regional market penetration. The website's content and structure support B2B and B2C engagement, with clear calls to action for joining the company and accessing learning solutions. The company appears to be investing in digital transformation and AI in education, signaling growth and innovation focus.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism, demonstrating baseline security and privacy awareness. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No public security policy, incident response information, or vulnerability disclosure channels are found, which limits transparency and readiness perception. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Microsoft Application Insights and Adobe DTM indicates active monitoring and analytics but also requires careful privacy management. Overall, the security posture is moderate with room for improvement in policy transparency and technical controls.

Recommendations

  1. Implement and publish a comprehensive privacy policy page clearly linked from the homepage and footer.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Publish a security policy and incident response contact information to improve transparency and trust.
  4. Provide a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Include data protection officer contact details to comply with GDPR and enhance privacy governance.

Technical notes

Notes

The website uses a modern front-end stack with asynchronous loading of analytics and tag management scripts, including Microsoft Application Insights and Adobe DTM. Fonts are preloaded for performance optimization. The site is responsive and mobile-optimized with good SEO meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML. Performance appears moderate with some heavy images but overall good structure. Accessibility features are basic but present. The site uses a privacy management SDK to handle cookie consent, indicating compliance efforts. Technical debt appears low, but improvements in security headers and privacy disclosures are recommended.
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.
