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

3 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. 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.

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Kahoot! holds a leading position in the education technology sector, leveraging interactive game-based learning to engage millions worldwide. Its competitive advantage lies in its user-friendly platform, extensive content marketplace, and strong brand recognition. Revenue streams include subscription plans and enterprise solutions. The target audience spans K-12 educators, higher education, and corporate clients. The company benefits from a robust partnership ecosystem and maintains a consistent brand presence. Growth indicators include continuous platform enhancements and global market penetration. Strategic observations highlight the importance of maintaining security and privacy compliance to sustain user trust and market leadership.

Security posture

The website exhibits a mature security posture with enforced HTTPS, domain transfer protection, and use of trusted third-party services for payments and analytics. However, the absence of DNSSEC and a publicly available security policy or incident response contacts represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Privacy compliance is well addressed with comprehensive privacy and cookie policies and consent mechanisms. Incident response readiness and vulnerability disclosure processes are not explicitly documented, which could be enhanced to improve transparency and trust.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing attacks.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Review and enhance HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  5. Maintain and regularly audit third-party libraries and integrations to mitigate potential vulnerabilities.

Notes

The website is built on a WordPress CMS with a custom theme (kahoot2017) and uses JavaScript libraries such as Flickity for UI components. Hosting is provided via AWS, indicated by the DNS nameservers. Payment processing is handled by Recurly, and analytics/tracking is managed through Google Tag Manager and OneTrust for cookie consent. The site demonstrates good mobile optimization and accessibility features. Performance is moderate, with room for optimization in loading speed and resource management. The technical stack is modern and well-integrated, supporting a scalable and user-friendly 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.
