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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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

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

    • 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

The business operates in the education sector, focusing on React and JavaScript developer training. It has a clear market position as a premium React course provider, supported by endorsements from industry professionals and trusted by developers at major tech companies. The business model is based on tiered paid course packages with bonus content and community access. The presence of team licenses indicates B2B engagement. The company maintains a strong digital presence with related domains and social media channels. Growth potential is supported by continuous content updates aligned with React's latest versions and technologies. Strategic partnerships with related course offerings enhance the ecosystem. The lack of public WHOIS data is a minor concern but does not detract from the business credibility based on content quality.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of explicit privacy and cookie policies, as well as lack of a security.txt or incident response contact, indicates gaps in compliance and incident readiness. The site does not appear to use intrusive tracking or advertising technologies, which supports user privacy. Overall, the security maturity is good but could be enhanced by formalizing privacy compliance and vulnerability disclosure mechanisms.

Recommendations

  1. Publish comprehensive privacy and cookie policies accessible from all pages to improve GDPR compliance and user trust.
  2. Add clear contact information for security incidents, including a security.txt file or dedicated security email address.
  3. Verify and update WHOIS domain registration details to ensure transparency and domain legitimacy.
  4. Consider implementing cookie consent mechanisms to comply with privacy regulations.
  5. Enhance analytics and tracking disclosures to align with best privacy practices.

Technical notes

Notes

The website is built on a modern React and Next.js stack, utilizing React 19 and Next.js 15 with advanced features like React Server Components and Suspense. The use of Framer Motion for animations and useSWR for data fetching indicates a sophisticated technical approach. The site is well-optimized for performance and mobile responsiveness, with good accessibility practices evident in content and component design. No CMS or hosting provider details were identified from the content. The technical implementation supports a high-quality user experience with minimal technical debt visible. Opportunities exist to improve SEO through enhanced metadata and structured data, as well as to formalize privacy and security documentation.
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.
