HashiCorp Vault is a centralized secrets management platform that provides secure storage, access control, and auditing for sensitive data like passwords, API keys, certificates, and encryption keys.
Problems it solves:
Secret sprawl: Eliminates hardcoded secrets in applications and configuration files
Access control: Provides fine-grained policies for who can access what secrets
Audit trail: Maintains detailed logs of all secret access and operations
Secret rotation: Automates credential rotation to reduce exposure risk
Encryption: Provides encryption-as-a-service for data protection
Example use case: Instead of storing database passwords in application config files, applications authenticate to Vault and retrieve credentials dynamically.
