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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

EF Education First holds a strong market position as a leading language education provider with a diversified portfolio including subsidiaries like EF Academy and Hult International Business School. Its business model focuses on direct-to-consumer education services, corporate training, and online platforms, generating revenue from tuition, program fees, and corporate contracts. The company targets a broad demographic from young students to professionals and enterprises. The website reflects a mature digital ecosystem with extensive program information, global reach, and integration with partner sites. The presence of multiple language and country-specific domains indicates a global localization strategy. EF's partnership ecosystem includes cultural exchange programs and executive education, enhancing its competitive advantage.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive data. Use of cookie consent mechanisms and privacy policies indicates compliance with GDPR. However, the absence of a dedicated security policy page, incident response contact details, and vulnerability disclosure mechanisms suggests areas for improvement in transparency and readiness. The integration of third-party scripts is managed securely, but continuous monitoring is recommended to mitigate risks from external dependencies. Overall, EF.fi maintains a secure environment suitable for handling personal data and online transactions, supporting its enterprise-grade operations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and dependencies to avoid vulnerabilities.
  5. Enhance accessibility features to meet or exceed WCAG standards for broader inclusivity.

Technical notes

Notes

EF.fi is built on a modern technology stack featuring Gatsby and React, enabling fast, performant, and SEO-friendly web pages. The site uses a headless CMS (Storyblok) inferred from asset URLs, facilitating content management and localization. Integration with analytics (Google Analytics, Tag Manager), marketing (Optimizely, Trustpilot), and consent management (OneTrust) tools reflects a mature digital marketing infrastructure. The site is mobile-optimized with responsive images and layouts. Performance is fast with preloading of critical assets. Technical debt appears minimal, but continuous monitoring of third-party integrations and security updates is advised to maintain operational stability and security.
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.
