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

Hugging Face is a leading technology company and AI community platform founded in 2016, headquartered in France. It provides a collaborative environment for machine learning practitioners to share and host models, datasets, and AI applications. The platform supports both open source community engagement and enterprise-grade solutions including compute resources and security features. Hugging Face has established itself as a key player in the AI ecosystem with a large user base and partnerships with major enterprises. Technically, the website is built using modern frameworks like Svelte, hosted on AWS infrastructure, and integrates payment processing via Stripe. The site is well-optimized for performance and mobile use, with clear navigation and professional design. Security posture is strong with HTTPS and domain protections, though there is room for improvement in explicit security headers and published security policies. Privacy compliance is mostly addressed with a comprehensive privacy policy, but lacks a visible cookie consent mechanism. Overall, Hugging Face demonstrates a mature digital presence with high trustworthiness and business credibility.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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

Hugging Face operates in the technology sector focusing on AI and machine learning. Its business model combines open source community offerings with paid compute and enterprise services. The company targets AI researchers, developers, and enterprises seeking scalable AI infrastructure and collaboration tools. Market positioning is strong as a central hub for AI models and datasets, supported by partnerships with major tech companies and a large active community. Revenue streams likely include compute usage fees and enterprise subscriptions. The platform's ecosystem includes extensive documentation, community forums, and integration with popular ML libraries, enhancing user engagement and growth potential.

Security posture

The website enforces HTTPS and uses domain status flags to prevent unauthorized domain changes, indicating good baseline security. However, no explicit security headers such as Content Security Policy or HSTS were detected in the provided data. There is no publicly visible security policy or incident response contact information, which could hinder transparency and trust in security matters. The absence of a vulnerability disclosure program or security.txt file limits the ability for external security researchers to report issues responsibly. The site uses CAPTCHA keys (though disabled on signup) and integrates with AWS WAF services, suggesting some level of bot mitigation. Overall, the security posture is solid but could be enhanced by publishing more security governance information and implementing additional HTTP security headers.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement and display a cookie consent banner to comply with GDPR and enhance privacy transparency.
  3. Add explicit HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  4. Publish a dedicated security policy page including incident response contacts and procedures.
  5. Establish a vulnerability disclosure program and provide a security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a modern tech stack centered around Svelte for frontend rendering, with integration of third-party services such as Stripe for payments and Plausible for analytics. Hosting and DNS are managed via AWS and OVH, providing robust infrastructure. The site demonstrates fast performance and excellent mobile optimization, with responsive design and accessibility considerations. The use of module preloading and deferred scripts indicates attention to load optimization. There is no detected CMS, suggesting a custom or static site generation approach. Technical risks are minimal but could include reliance on third-party scripts and lack of some security headers. Overall, the technical implementation supports 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.
