How Vault Secrets Operator (VSO) automates secret management for enterprises on Kubernetes

Vault Secrets Operator (VSO) automates secret lifecycle management by syncing HashiCorp Vault secrets into Kubernetes clusters using Kubernetes-native patterns.

• •Uses Custom Resource Definitions to map Vault secrets to Kubernetes secrets without requiring application code changes
• •Supports two modes: standard mode storing secrets in etcd, and protected secrets mode using CSI drivers for ephemeral in-memory storage in regulated environments
• •Automatically handles secret generation, rotation, revocation, drift remediation, and triggers rolling restarts for credential updates
• •Runs a single cluster instance for efficiency and integrates with Vault events for instant secret updates instead of polling
• •Provides centralized secret management with least-privilege access controls, replacing legacy sidecar injection patterns
