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

The website www.koolearn.com is a comprehensive online education platform affiliated with the well-known New Oriental brand, offering a wide range of courses including exam preparation for graduate studies, language proficiency tests (IELTS, TOEFL, GRE, GMAT, SAT, ACT), teacher certification, and multiple language learning options. The platform targets students and professionals seeking remote learning opportunities with personalized and interactive course offerings. Technically, the site is built using modern web technologies such as React and Next.js, with good performance and mobile optimization. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though explicit security headers and privacy policies are lacking. The absence of WHOIS data reduces transparency but does not detract significantly from the site's legitimacy given the strong brand association and professional presentation. Overall, the site is trustworthy and well-positioned in the online education market.

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. 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 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Koolearn operates as a large-scale online education service under New Oriental, a leading education group in China. Its business model revolves around paid and free online courses targeting exam candidates and language learners. The platform leverages a broad teacher network and advanced content development teams to maintain competitive advantage. The presence of VIP and customized courses indicates a tiered revenue stream. Partnerships with related domains and use of promotional short links suggest active marketing strategies. The site’s extensive course catalog and free public classes support strong user engagement and brand loyalty.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and no exposed sensitive data in the HTML content. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security or incident response policies indicate room for improvement. No vulnerability disclosures or security contact channels are visible, which could hinder incident reporting and response. Privacy compliance is weak due to missing privacy and cookie policies, which is a compliance risk especially under GDPR and other data protection regulations. Overall, the security maturity is good but could be enhanced by formalizing policies and improving transparency.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear user consent mechanisms to improve privacy compliance.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen security posture.
  3. Provide clear contact information for security incidents and vulnerability disclosures to facilitate incident response.
  4. Enhance transparency by publishing WHOIS data or using verified domain registration to improve trustworthiness.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a modern React-based framework (Next.js) with server-side rendering and static asset delivery via a CDN (koocdn.com). It includes analytics from Baidu and Gio, and employs deferred script loading for performance optimization. The site is mobile-optimized and accessible with good SEO practices including meta tags and structured navigation. Hosting appears to be on a Chinese cloud provider, likely Alibaba Cloud, inferred from CDN domains. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is fast with good resource preloading. Technical risks include reliance on multiple third-party scripts and lack of explicit security headers.
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.
