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

Jan.ai is an open-source AI chat platform developed by Grit Labs, offering a privacy-focused alternative to ChatGPT by running AI models entirely offline on users' devices. The platform targets privacy-conscious users and AI enthusiasts who prefer local AI processing without data exposure. With over 3.5 million downloads and a strong GitHub presence, Jan.ai has established itself as a niche player in the AI technology sector. Technically, the website leverages modern frameworks such as Next.js and React, hosted behind Cloudflare DNS, ensuring fast performance and good mobile optimization. Security posture is strong with HTTPS enforced and multiple security headers present, though DNSSEC is not enabled. However, the site lacks explicit privacy and cookie policies, as well as contact information and formal security policies, which are areas for improvement. Overall, Jan.ai presents a trustworthy and professional digital presence with room to enhance compliance and transparency.

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

4 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 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

  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

Jan.ai operates in the technology sector focusing on AI and privacy. Its business model is based on free and open-source software, attracting a community-driven user base. The project benefits from active engagement on GitHub, Discord, and Twitter, which supports growth and user support. The absence of monetization details suggests a community or donation-supported model. The company, Grit Labs, is US-based and has maintained domain registration since 2017, indicating stability. The platform's competitive advantage lies in offline AI capabilities and privacy emphasis, appealing to users wary of cloud-based AI services. Strategic partnerships or subsidiaries are not evident, but integration with Hugging Face and cloud AI connectors indicates ecosystem connectivity.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. The domain status clientTransferProhibited adds protection against unauthorized transfers. No DNSSEC is enabled, which could be improved. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of published security policies, incident response contacts, and vulnerability disclosure mechanisms limits transparency and preparedness. The absence of privacy and cookie policies also poses compliance risks, especially under GDPR. Overall, the security maturity is good but could be enhanced by formalizing policies and disclosure channels.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  3. Add explicit security policies and incident response procedures accessible on the website.
  4. Implement a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  5. Provide clear contact information for business and security inquiries to enhance transparency.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring a performant and responsive user experience. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site includes preloaded images and scripts for optimized loading. SEO is well addressed with appropriate meta tags and Open Graph data. Accessibility features such as keyboard navigation hints and responsive design are present. No CMS is detected, indicating a custom or static site generation approach. The technical infrastructure is robust with minimal technical debt visible, though enabling DNSSEC and adding formal compliance pages would further strengthen the 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.
