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

6 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 Policy found

      GDPR requires clear information about cookie usage

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

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

The business operates as an online educational information platform connecting learners with training institutions. It leverages a network of subdomains and partner sites to provide comprehensive services. The platform's market position is strong in the regional education sector, with a focus on language and vocational training. Revenue likely derives from institutional partnerships and course promotions. The presence of a school management backend indicates B2B services. The company demonstrates moderate digital maturity with room for improvement in privacy and security compliance.

Security posture

The website uses HTTPS and integrates Baidu Analytics but lacks visible security headers and explicit cookie consent mechanisms, indicating partial security and privacy compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data raises concerns about domain legitimacy, though the active and professional site presence mitigates some risk. Incident response and security policy information are not publicly available, suggesting limited transparency in security governance.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Add a clear cookie consent banner and privacy policy updates to comply with international privacy regulations including GDPR.
  3. Publish security policy and incident response contact information to improve transparency and trust.
  4. Regularly update JavaScript libraries and dependencies to mitigate vulnerabilities.
  5. Consider registering WHOIS data publicly or using verified privacy protection services to improve domain legitimacy perception.

  3. No explicit privacy or cookie consent banners detected, indicating partial privacy compliance.
  4. No security headers detected in provided data; security posture could be improved.
  5. Site uses Baidu Analytics for user tracking.
  6. No adult or explicit content detected; content is safe for general audiences.
  7. Multiple internal subdomains and partner domains indicate a mature ecosystem.
  8. Site is mobile optimized with alternate mobile URLs provided.
Technical notes

Notes

The website employs a traditional tech stack including jQuery 1.11.3 and Swiper.js for UI components, with Baidu Analytics for tracking. The site is mobile optimized with alternate mobile URLs and uses CSS3 and HTML5 standards. Performance is moderate with room for optimization. No CMS or hosting provider details were detected. Accessibility features are basic, and SEO is adequately addressed with meta tags and structured navigation. Technical debt is indicated by older jQuery version and lack of modern frameworks. Opportunities exist to modernize the stack and improve security configurations.
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.
