0–100, higher is better. How it is calculated

Mistral AI is a French technology company founded in 2019 specializing in providing a frontier AI platform for enterprises. Their offerings include configurable AI assistants, autonomous agents, multimodal AI, and developer tools such as AI coding assistants and builder APIs. The company positions itself as a leader in open-source AI models and enterprise-grade AI deployments, targeting developers and businesses seeking customizable AI solutions. Technically, the website is built on a modern stack using Next.js and Cloudflare services, delivering fast and mobile-optimized experiences. Security posture is strong with HTTPS enforcement and domain transfer protection, though DNSSEC is not enabled and privacy compliance documentation is lacking. Overall, the website is professional and trustworthy, but would benefit from enhanced privacy and security disclosures to improve compliance and user trust.

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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. 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

Mistral AI operates in the competitive AI technology sector, focusing on enterprise customers and AI builders. Their business model revolves around providing AI platform services, APIs, and expert-led AI acceleration services. The company emphasizes customization, privacy-first deployments, and integration with enterprise data. Their market position is that of an innovative AI platform provider with open models, competing with other AI infrastructure companies. The presence of a console subdomain indicates a SaaS or API-driven revenue stream. Partnerships with cloud providers are implied but not explicitly detailed. The company’s growth potential is supported by a comprehensive product suite and expert services. However, the lack of direct contact emails or phone numbers may limit immediate customer engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and domain transfer protection set. Use of Cloudflare DNS and CDN adds resilience and DDoS protection. However, DNSSEC is not enabled, which is a recommended enhancement. No security.txt or vulnerability disclosure policy is published, which limits transparency for security researchers. No direct security contact emails are provided. The website avoids exposing sensitive data or using vulnerable libraries in the visible content. Cookie consent is managed by axept.io, but no explicit cookie or privacy policies are found, indicating compliance gaps. Overall, the security posture is good but could be improved with formal policies and DNSSEC.

Recommendations

  1. Publish comprehensive privacy and cookie policies to ensure GDPR and global privacy compliance.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Create and publish a security.txt file or vulnerability disclosure policy to facilitate responsible security reporting.
  4. Add explicit security and incident response contact channels such as security@ or abuse@ emails.
  5. Improve accessibility features to meet WCAG standards and enhance user inclusivity.

Technical notes

Notes

The website is built using Next.js, a modern React framework, indicating a contemporary and scalable technical infrastructure. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site uses Google Tag Manager for analytics and axept.io for cookie consent management. Images are optimized with responsive srcsets and lazy loading, contributing to fast load times. The site is mobile-optimized and has good SEO metadata including Open Graph and Twitter cards. No CMS is detected, suggesting a custom or proprietary content management approach. Technical debt appears low, but the absence of DNSSEC and formal security policies are areas for improvement. Overall, the technical implementation supports a robust and professional online presence.
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.
