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. 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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 technology sector, focusing on AI-driven conversational services targeting a broad general audience. The business model includes free access with implied paid subscription tiers. The domain age and registration details are consistent with the product's launch timeline. The company benefits from strong brand recognition and a partnership ecosystem centered around OpenAI. The lack of direct contact information on the site suggests a focus on digital self-service and automated support. The platform's key competitive advantages include cutting-edge AI technology, extensive language support, and a user-friendly interface. Growth indicators include continuous feature updates and a large user base. Strategic observations highlight the importance of enhancing security transparency and expanding contact channels for incident response.

Security posture

The website exhibits a mature security posture with HTTPS enforced, domain status locks preventing unauthorized changes, and use of nonce attributes in scripts to mitigate injection risks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, DNSSEC is not enabled, which could be a potential area for improvement. The absence of a published security policy or incident response contacts limits transparency. Compliance with GDPR is indicated by the privacy policy and cookie consent mechanisms. Overall, the security culture appears strong but could benefit from formalizing vulnerability disclosure processes and publishing security contact information.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a dedicated security policy page including incident response procedures and security contact emails.
  3. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Add clear and accessible contact information for security and general inquiries to improve trust and responsiveness.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are introduced.

Technical notes

Notes

The website is built on a modern React framework with React Router for routing and uses modular JavaScript loaded from a CDN. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site uses advanced CSS and accessibility features, including color scheme preferences and screen reader support. Performance is optimized with module preloading and minimal blocking scripts. The technical debt appears low, with opportunities to further modernize by enabling DNSSEC and expanding security headers. The infrastructure supports scalability and high availability, suitable for a large user base. Technical risks are minimal but should be monitored continuously.
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.
