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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 · found on this site
  • 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 institution positions itself strongly within the education sector as part of a large international network of 42 campuses, boasting 56 campuses across 32 countries and serving over 44,000 students. Its business model is based on providing free, high-quality coding education with a focus on project-based and peer learning. The school benefits from certifications such as Qualiopi, enhancing its credibility. The website's content and navigation are clear and professional, supporting user engagement and conversion. The social media ecosystem is robust, supporting outreach and community building. The lack of direct contact emails or phone numbers on the homepage suggests a preference for managed contact channels, likely to streamline inquiries.

Security posture

The website demonstrates a good security posture with HTTPS enforced and no exposed sensitive data. Cookie consent is managed via a reputable plugin, and tracking is limited to Google Analytics. However, the absence of explicit security policies, incident response contacts, and security headers like Content-Security-Policy or X-Frame-Options indicates room for improvement. No vulnerabilities or suspicious domains were detected. The domain registration is transparent and consistent with the business, enhancing trust. Overall, the security maturity is good but could be elevated by publishing dedicated security documentation and enhancing HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Enhance transparency by including direct company contact emails or phone numbers for support and inquiries.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Bootstrap, and Google Analytics for tracking. Hosting is managed via Cloudflare, providing DNS and CDN services. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance is moderate, with room for optimization in image loading and script management. The use of cookie consent plugins ensures compliance with privacy regulations. No technical debt or deprecated technologies were detected, indicating good maintenance practices. Opportunities exist to improve security headers and streamline analytics for better privacy compliance.
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.
