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. 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';…

  2. GDPR outside view

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

    • 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

    • 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 organization targets individuals interested in software development and engineering, offering free courses that likely attract a broad demographic. The business model is non-traditional, focusing on education without direct fees, which may rely on partnerships or sponsorships. The website's market position is strong within the educational sector, emphasizing innovation and accessibility. There is no evidence of direct revenue streams or commercial partnerships visible on the site. The lack of explicit contact information or business registration details suggests a focus on community and educational outreach rather than commercial operations.

Security posture

The website uses Cloudflare DNS services, which provides a baseline of security and performance. However, there is no visible implementation of security headers such as Content-Security-Policy or X-Frame-Options, which are recommended best practices. SSL/TLS configuration details are not explicitly available, but the use of HTTPS is implied by the URL. No incident response or security policy information is provided, indicating a potential gap in transparency and preparedness. The absence of privacy and cookie policies also suggests incomplete compliance with data protection regulations such as GDPR.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to enhance compliance and user trust.
  2. Add security headers to improve protection against common web vulnerabilities.
  3. Provide clear contact information including emails and phone numbers for support and incident reporting.
  4. Establish and disclose an incident response policy and contact channels for security issues.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built using standard HTML5 and CSS3 technologies, hosted behind Cloudflare which provides DNS and potential CDN services. The site is moderately optimized for mobile devices and SEO, with appropriate meta tags and Open Graph data for social sharing. However, there is no evidence of a CMS or advanced frameworks in use. Performance appears moderate with no explicit indicators of slow loading. The site lacks advanced accessibility features and security best practices such as security headers. There is an opportunity to modernize the technical stack by integrating analytics, security policies, and enhanced accessibility 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.
