Langfuse Cloud security model

The managed service combines a security program, tenant isolation, and customer-controlled data management. Production systems are monitored and reviewed through a documented security process.

Security posture

Regular security reviews, dependency maintenance, encryption in transit and at rest, and controls aligned with SOC 2 and ISO 27001.

Tenant isolation

Product data is scoped to projects. API keys are project-scoped and authenticated requests pass through authorization checks.

Customer controls

Teams can reduce what reaches Langfuse with masking, configure retention, choose a region, and use enterprise identity controls.
