How Hugging Face Scaled Secrets Management for AI Infrastructure

Hugging Face, a leading AI platform, has witnessed exponential growth, with over 4 million developers utilizing its model hub. As the platform expanded, so did the complexity of managing sensitive configuration data—secrets. The challenge was to ensure security while maintaining developer efficiency across a multi-cloud infrastructure spanning AWS, Azure, and GCP.

To tackle this, Hugging Face explored various secret management solutions, ultimately selecting Infisical over alternatives like HashiCorp Vault. This article details their transition, integration, and the security and efficiency improvements that followed.

Migration to Infisical: A Strategic Shift

Hugging Face faced several key challenges in secrets management:

Secret sprawl due to inconsistent handling across environments.
Complex permission management requiring robust RBAC integrated with Okta SSO.
Local development inefficiencies, where traditional .env files posed security risks.
Manual secret rotation, which became a burden after a security incident exposed credentials.

Infisical emerged as the ideal solution due to its developer-friendly interface, multi-cloud abstraction, and tight security controls. The migration process involved rearchitecting secret management workflows to enhance efficiency and security.

Kubernetes Integration

Kubernetes is central to Hugging Face’s infrastructure. Infisical’s Kubernetes Operator automated secrets management by:

1. Monitoring and syncing secrets from Infisical.

2. Updating Kubernetes secrets automatically when changes occur.

3. Triggering container reloads when secrets are modified.

Despite automation capabilities, Hugging Face engineers opted for manual redeployments in high-traffic scenarios (handling over 10 million requests per minute) to maintain control over deployments.

Enhancing Local Development

Infisical’s CLI replaced .env files, injecting secrets directly into development environments. This eliminated security risks while aligning local configurations with production standards. Developers benefited from a streamlined onboarding process with minimal friction.

Security and Access Control

Infisical integrated seamlessly with Okta-based RBAC, ensuring:

– Automatic permission mapping from Okta groups.

Restricted access based on developer roles (frontend, backend, admin).

– Secure credential sharing among ML/AI researchers.

Centralized auditing and automated secret rotation further strengthened security, addressing concerns raised by past incidents.

CI/CD & Infrastructure Integration

To enhance security in the CI/CD pipeline, Hugging Face embedded Infisical into GitHub Actions using OIDC authentication and Terraform integration. This ensured:

– Secure deployments via self-hosted GitHub runners.

– Consistent secrets management across cloud environments.

A seamless experience from local development to production deployment.

Key Outcomes & Insights

Migrating to Infisical delivered significant benefits:

✅ Faster developer onboarding with self-serve workflows.

✅ Automated auditing & fine-grained RBAC, reducing security risks.
✅ Standardized secret management across Kubernetes, CI/CD, and cloud environments.

✅ Improved security posture, enabling proactive incident response.

As Adrien Carreira, Head of Infrastructure at Hugging Face, stated:

“Infisical provided all the functionality and security settings we needed to boost our security posture and save engineering time. Whether you’re working locally, running Kubernetes clusters in production, or operating secrets within CI/CD pipelines, Infisical has a seamless prebuilt workflow.”

What Undercode Says:

Hugging Face’s approach highlights an engineering-first strategy for secrets management, balancing security and operational efficiency. Let’s analyze key takeaways:

1. Choosing the Right Tool Matters

While HashiCorp Vault is a well-known solution, it introduces operational complexity. Infisical’s lightweight nature and developer-friendly interface made it a better fit. This reflects a broader trend—engineering teams prioritize usability alongside security.

2. Automation vs. Control: Finding the Balance

Infisical’s Kubernetes Operator automates secret updates, yet Hugging Face engineers preferred manual redeployments in critical production workloads. This demonstrates a mature DevOps strategy, where teams selectively automate to minimize disruptions.

3. The End of `.env` Files?

Local development often relies on .env files, which pose security risks. By injecting secrets dynamically via CLI, Hugging Face eliminated outdated practices, ensuring secure and standardized configurations. This approach is likely to become industry standard.

4. Zero-Trust Security in Secrets Management

Integrating with Okta’s RBAC framework enabled least-privilege access control. The lesson? Zero-trust security models are crucial for protecting sensitive data in AI-driven organizations.

5. CI/CD Security Must Be a Priority

Infisical’s integration with GitHub Actions and Terraform reflects a growing trend—secrets management is now a core part of DevOps workflows. Organizations failing to embed security into CI/CD risk credential leaks and compliance failures.

6. Cloud-Agnostic Approaches Are the Future

Hugging Face operates across AWS, Azure, and GCP. Infisical’s multi-cloud compatibility ensured consistent security policies, reinforcing the shift toward cloud-agnostic infrastructures.

7. The Cost of Poor Secret Management

A previous security incident involving leaked credentials underscored the high stakes of mismanaged secrets. Organizations must proactively address security risks rather than react to breaches.

Infisical vs. HashiCorp Vault: A Case Study in Simplicity
HashiCorp Vault offers robust security but comes with a steep learning curve. Infisical’s intuitive design and developer focus made it a better choice for Hugging Face. Teams should weigh usability vs. complexity when choosing security solutions.

9. The Future of Secrets Management

With AI adoption skyrocketing, infrastructure security must evolve. Hugging Face’s success with Infisical signals a paradigm shift—from legacy secrets management to developer-centric, automated solutions.

10. Practical Takeaway: Make Security the Easy Path

As the case study illustrates, when secure workflows are frictionless, teams naturally adopt them. The key to strong security? Making the secure path the easiest path.

Fact Checker Results

✅ Infisical is gaining traction—Hugging Face is not the only major AI company adopting it.
✅ Secrets mismanagement is a major security risk—past breaches confirm the necessity of proactive security.
✅ AI infrastructure demands new security paradigms—traditional secrets management tools struggle to keep up.
