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

2 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 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 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

Course Masters operates in the education sector, specifically targeting online course creators and marketers. Its business model revolves around providing expert-led masterclasses and resources to help entrepreneurs successfully launch and sell online courses. The platform's partnership with LearnWorlds enhances its technical capabilities and market reach. The presence of an affiliate program indicates a strategy to expand user acquisition through partnerships. The website's content and design reflect a focus on quality and user engagement, supported by testimonials and user ratings. The integration of multiple social media channels and marketing tools suggests an active digital marketing approach. While the company size is medium, no explicit founding year or parent company information is available, indicating a possibly independent or relatively new entity.

Security posture

The security posture of Course Masters is generally good. The website enforces HTTPS with a valid TLS certificate supporting modern protocols (TLS 1.2 and 1.3) and no known SSL vulnerabilities. Security headers such as X-Frame-Options and Strict-Transport-Security are present, though HSTS is not fully enabled with preload or includeSubDomains flags. Cookies are set with Secure and HttpOnly flags and SameSite=None, enhancing session security. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of OCSP stapling and certificate transparency compliance are areas for improvement. There is no explicit security policy or incident response information publicly available, which could be enhanced to improve transparency and readiness. Overall, the platform follows standard security best practices but could benefit from additional security hardening measures.

Recommendations

  1. Enable full HSTS with includeSubDomains and preload to strengthen HTTPS enforcement.
  2. Implement OCSP stapling to improve TLS certificate revocation checking and reduce latency.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve incident response communication.
  4. Add additional security headers such as Content-Security-Policy and Referrer-Policy to enhance protection against common web attacks.
  5. Provide explicit security policy and incident response information on the website to increase user trust and demonstrate security maturity.

Technical notes

Notes

The website is built on the LearnWorlds platform, utilizing a modern tech stack including jQuery, Uppy for file uploads, Wistia for video hosting, and Stripe for payment processing. It is hosted on Google Cloud infrastructure with Cloudflare providing CDN and security services. The site uses multiple third-party integrations for marketing and analytics such as Facebook Pixel, Mixpanel, HubSpot, Google Tag Manager, and Hotjar. The site is mobile-optimized with responsive design and custom fonts loaded via WebFont. Performance is moderate with no explicit load time data but optimized resource loading is observed. The site uses standard HTML5 and CSS3 with no major technical debt or errors detected. Opportunities exist to improve accessibility and SEO further by adding ARIA attributes and structured data markup. Overall, the technical implementation supports a robust and scalable online education platform.
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.
