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

Les Sherpas is a French education platform specializing in personalized tutoring and online courses for students across various academic levels. The company positions itself as a flexible and quality-driven service provider, leveraging a proprietary platform that integrates messaging and videoconferencing to enhance the learning experience. The website is content-rich, featuring extensive user testimonials and structured data to boost SEO and trust. Technically, the site uses modern web standards and is hosted by o2switch, with moderate performance and good mobile optimization. Security is adequate with HTTPS and valid SPF records, but lacks advanced features such as HSTS and OCSP stapling, and no security headers are present. Privacy compliance is basic, with a privacy policy found but no cookie consent mechanism detected. Overall, the site demonstrates a strong business credibility and user trust, though security and privacy practices could be improved.

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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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';…

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 platform targets parents and students in France seeking tailored academic support through online and in-person tutoring. Its competitive advantage lies in the quality assurance of tutors, personalized learning paths, and an integrated platform that simplifies course management. Revenue likely derives from paid tutoring sessions, with a broad offering of subjects and levels. The company maintains an active social media presence and leverages user reviews to build trust. Partnerships include email service providers indicated by SPF records. The business model is scalable and positioned well within the French education market, focusing on innovation and customer satisfaction.

Security posture

The website employs HTTPS with TLS 1.3 and 1.2 protocols, free from known SSL vulnerabilities. DNS records include a valid SPF policy, but DNSSEC is not enabled. The absence of HSTS and OCSP stapling reduces protection against certain attacks and revocation delays. No security headers such as Content-Security-Policy or X-Frame-Options are detected, which could expose the site to clickjacking or content injection risks. No explicit incident response or security policies are published. Privacy compliance is minimal, lacking cookie consent mechanisms and detailed GDPR adherence indicators. Overall, the security posture is moderate but could benefit from implementing best practices and transparency.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS.
  2. Implement OCSP stapling to improve SSL certificate revocation checking performance and security.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Deploy a cookie consent banner to comply with GDPR and inform users about tracking.
  5. Publish a detailed privacy policy with GDPR compliance statements and data retention policies.
  6. Consider enabling DNSSEC to enhance DNS security and prevent spoofing.
  7. Establish and publish an incident response policy and contact channels for security issues.
  8. Improve accessibility features to enhance usability for all users.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, incorporating Google Tag Manager for analytics and tracking. It uses a custom platform hosted on o2switch servers with DNS managed by o2switch nameservers. Performance is moderate with a page load time of approximately 4 seconds and 11 resource requests. The site is mobile optimized with responsive design elements. SEO is enhanced by comprehensive meta tags, Open Graph data, and rich JSON-LD structured data including detailed organization and product information. No CMS or major frameworks are explicitly detected. The technical stack is modern but could benefit from additional security and privacy enhancements.
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.
