Security is a top priority at Hugging Face, and we're committed to continually enhancing our defenses to safeguard our users. In our ongoing security efforts, we have developed a range of security features designed to empower users to protect themselves and their assets. In this blog post, we'll take a look at our current security landscape as of August 6th, 2024, and break down key security features available on the Hugging Face Hub.
This post is broken down into two parts: in the first sections, we explore the essential security features available to all users of the Hub. Then in the second section we describe the advanced controls available to Enterprise Hub users.
The following security features are available to all users of the Hugging Face Hub. We highly recommend that you use all of these controls where possible as it will help increase your resiliency against a variety of common attacks, such as phishing, token leaks, credential stuffing, session hijacking, etc.
User Access Tokens are required to access Hugging Face via APIs. In addition to the standard "read" and "write" tokens, Hugging Face supports "fine-grained" tokens which allow you enforce least privilege by defining permissions on a per resource basis, ensuring that no other resources can be impacted in the event the token is leaked. Fine-grained tokens offer a plethora of ways to tune your token, see the images below for the options available. You can learn more about tokens here: https://huggingface.co/docs/hub/en/security-tokens
Two factor authentication adds an extra layer of protection to your online accounts by requiring two forms of verification before granting access. 2FA combines something you know (like a password) with something you have (such as a smartphone) to ensure that only authorized users can access sensitive information. By enabling 2FA, you can greatly reduce the risk of unauthorized access from compromised passwords, credential stuffing and phishing. You can learn more about 2FA here: https://huggingface.co/docs/hub/en/security-2fa
Although Git has an authentication layer to control who can push commits to a repo, it does not authenticate the actual commit author. This means it's possible for bad actors to impersonate authors by using git config --global user.email you@company.com and git config --global user.name Your Name. This config does not automatically give them access to push to your repositories that they otherwise wouldn't have - but it does allow them to impersonate you anywhere they can push to. This could be a public repository or a private repository using compromised credentials or stolen SSH key.
Commit signing adds an additional layer of security by using GPG to mitigate this issue; you can learn more at Git Tools: Signing Your Work. Hugging Face gives authors the ability to add their GPG keys to their profile. When a signed commit is pushed, the signature is authenticated using the GPG key in the authors profile. If it's a valid signature, the commit will be marked with a “Verified” badge. You can learn more about commit signing here: https://huggingface.co/docs/hub/en/security-gpg
Organizations on Hugging Face have access to Organizational Access Controls. This allows teams and businesses to define least privilege access to their organization by assigning "read", "write", "contributor" or "admin" roles to each of their users. This helps ensure that the compromise of one user account (such as via phishing) cannot affect the entire organization. You can learn more about Organizational Access Controls here: https://huggingface.co/docs/hub/en/organizations-security
Hugging Face implements an automated security scanning pipeline that scans all repos and commits. Currently, there are three major components of the pipeline:
trufflehog filesystem commandIn the event a malicious file is detected, the scans will place a notice on the repo allowing users to see that they may potentially be interacting with a malicious repository. You can see an example of a (fake) malicious repository here: https://huggingface.co/mcpotato/42-eicar-street/tree/main.
For any verified secret detected, the pipeline will send an email notifying the owner so that they can invalidate and refresh the secret.
Verified secrets are the ones that have been confirmed to work for authentication against their respective providers. Note, however, that unverified secrets are not necessarily harmless or invalid: verification can fail due to technical reasons, such as in the case of down time from the provider.

In addition to the security features available to all users, Hugging Face offers advanced security controls for Enterprise users. These additional controls allow enterprises to build a security configuration that is most effective for them.
Single sign-on (SSO) allows a user to access multiple applications with one set of credentials. Enterprises have widely moved to SSO as it allows their employees to access a variety of corporate software using identities that are managed centrally by their IT team. Hugging Face Enterprise supports SSO with both the SAML 2.0 and OpenID Connect (OIDC) protocols, and supports any compliant provider such as Okta, OneLign, Azure AD, etc. Additionally, SSO users can be configured to be dynamically assigned access control roles based on data provided by your identity provider. You can learn more about SSO here: https://huggingface.co/docs/hub/en/security-sso
In addition to the base organizational access controls, Enterprises can define and manage groups of repositories as Resource Groups. This allows you to segment your resources by team or purpose, such as "Research", "Engineering", "Production" so that the compromise of one segment can not affect others. You can learn more about Resource Groups here: https://huggingface.co/docs/hub/en/security-resource-groups
✨New✨ Enterprise users can now manage which tokens can access their organization and resources. Organization owners can enforce the usage of fine-grained tokens and require administrator approval for each token. Administrators can review and revoke each token that has access to their repositories at any time.

Enterprise users have access to data residency controls, which allow them to define where repositories (models, datasets, spaces) are stored. This allows for regulatory and legal compliance, while also improving download and upload performance by bringing the data closer to your users. We currently support US and EU regions, with Asia-Pacific coming soon. We call this feature "Storage Regions". You can learn more about Data Residency here: https://huggingface.co/docs/hub/en/storage-regions
Enterprise users have access to audit logs that allow organization admins to review changes to repositories, settings and billing. The audit logs contain the username, location, IP, and action taken and can be downloaded as a JSON file which can be used in your own security tooling. You can learn more about Audit Logs here: https://huggingface.co/docs/hub/en/audit-logs
Hugging Face is SOC2 Type 2 certified and GDPR compliant. We offer Business Associate Addendums for GDPR data processing agreements to Enterprise Plan users. You can learn more about our Compliance efforts here: https://huggingface.co/docs/hub/en/security
Hugging Face offers custom agreements and development of features and tools for Enterprise accounts which are established via Statement of Work (SoW) and Service Level Agreements (SLA). You can reach out directly to sales to discuss your options at https://huggingface.co/contact/sales.
