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. 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)

      • 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"

    • 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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 company operates in the education sector with a unique business model leveraging hypnosis for language learning, differentiating itself from traditional language schools. Their market position is niche but well-defined, targeting learners who value innovative and relaxed learning methods. The business model includes both in-person and online courses, allowing flexibility and scalability. Customer testimonials and social media presence enhance credibility. The domain age and registration details align with the business claims, supporting legitimacy. No parent or subsidiary companies were identified, indicating a focused small business operation.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled, use of Google reCAPTCHA to protect forms, and cookie consent mechanisms. However, the absence of DNSSEC and lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represent areas for improvement. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security incidents. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate for the business size but could be enhanced to meet higher compliance standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Add explicit incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website is built on a WordPress CMS platform with a modern tech stack including WooCommerce, Contact Form 7, Google Tag Manager, and Cookiebot. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. The site uses external services such as Vimeo for video content and Google Maps for location display. Hosting details are not explicit but domain registration is with Gandi SAS and DNS servers are ns1.netnerd.com and ns2.netnerd.com. The site could benefit from enhanced security headers and DNSSEC to reduce technical risks. Overall, the technical infrastructure supports the business needs effectively with room for security and compliance improvements.
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.
