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. 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"

      • ASVS V3.4.3

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 and technology sectors, targeting individuals and professionals seeking blockchain expertise. Its business model includes online and blended learning with university certification and corporate partnerships, enhancing credibility and market reach. The presence of well-known partners and a professional teaching staff strengthens its competitive advantage. The platform's content and marketing focus on practical, collaborative, and continuous learning, appealing to a broad audience. Growth potential is supported by the increasing demand for blockchain skills and the strategic alliances with industry leaders.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no visible incident response or security policy information, which could be enhanced to improve transparency and readiness. Overall, the security measures are adequate for the business type but could be strengthened to mitigate advanced threats.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and user trust.
  3. Regularly audit and update third-party scripts and plugins to prevent vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

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.
