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

OpenAI positions ChatGPT as a leading AI conversational platform with a freemium business model offering advanced AI services including text generation, image generation, and data analysis. The company targets a wide user base from casual users to enterprise customers. The domain registration and hosting arrangements are consistent with a reputable technology enterprise. The website content and metadata align with OpenAI's branding and market positioning. No direct contact information is provided on the landing page, indicating a focus on self-service and digital engagement. The platform integrates advanced features such as voice input and file uploads, reflecting ongoing innovation and user-centric development.

Security posture

The website enforces HTTPS and uses domain status locks to prevent unauthorized changes, indicating good baseline security hygiene. However, DNSSEC is not enabled, which is a potential area for improvement to protect against DNS spoofing. No explicit security headers were detected in the HTML content, and no published security or incident response policies were found, which could be enhanced to improve transparency and trust. No vulnerabilities or exposed sensitive data were identified. The site does not appear to expose any deprecated or vulnerable libraries. Forms are secured and do not reveal sensitive information. Overall, the security posture is good but could benefit from additional published policies and DNS security enhancements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and user trust.
  3. Implement and report standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Consider providing verified company contact information for support and security inquiries to enhance credibility.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are introduced.

Technical notes

Notes

The website is built using a modern React framework with React Router for routing and uses ES modules for script loading. It leverages a CDN (cdn.oaistatic.com) for static assets, improving load times and global availability. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA attributes. SEO is supported by proper meta tags and Open Graph metadata. No CMS was detected, indicating a custom or proprietary platform. Performance is fast with preloading of modules and efficient resource management. The technical stack is modern and well-maintained, supporting a scalable and reliable user experience.
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.
