Cloud-native SaaS platform for unified secrets management and machine identity security
Discover top open-source software, updated regularly with real-world adoption signals.

Secure secrets management with encryption and access control
Vault provides unified secrets management with encrypted storage, dynamic credential generation, data encryption, automated leasing, and comprehensive audit logging for modern infrastructure.

Vault is a secrets management tool designed to control access to sensitive data such as API keys, passwords, certificates, and database credentials. It provides a unified interface for managing secrets across diverse platforms while maintaining strict access controls and detailed audit trails.
Vault encrypts data before writing to persistent storage, ensuring raw storage access alone cannot compromise secrets. It generates dynamic, short-lived credentials on-demand for systems like AWS and SQL databases, automatically revoking them when leases expire. The platform also functions as an encryption-as-a-service layer, allowing teams to encrypt and decrypt data without storing it, enabling developers to leverage enterprise-grade encryption without building custom solutions.
Designed for security teams, platform engineers, and DevOps practitioners managing secrets at scale, Vault supports multiple storage backends including disk and Consul. The leasing and renewal system provides time-bound access to secrets, while built-in revocation capabilities enable rapid response to security incidents by revoking individual secrets or entire trees of credentials. Comprehensive documentation, tutorials, and certification programs support both new users and experienced practitioners.
When teams consider Hashicorp Vault, these hosted platforms usually appear on the same shortlist.

Cloud-native SaaS platform for unified secrets management and machine identity security

Managed service for securely storing, retrieving, and rotating application secrets (credentials, API keys, etc.)

Cloud service for secure storage and management of cryptographic keys, secrets, and certificates
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Dynamic Database Credentials
Applications request time-bound database credentials from Vault, which automatically generates and revokes them, eliminating static credential sprawl and reducing breach impact.
Cloud Provider Access Management
Services obtain short-lived AWS or Azure credentials on-demand, ensuring credentials expire automatically and reducing the risk of leaked long-term access keys.
Encryption-as-a-Service
Development teams encrypt sensitive data before storing it in databases without implementing custom encryption, while security teams maintain centralized control over encryption policies.
Certificate Management
Automated certificate generation and renewal for microservices eliminates manual certificate handling and ensures consistent PKI practices across infrastructure.
Vault manages API keys, passwords, certificates, database credentials, cloud provider access keys, and arbitrary key-value pairs. It supports both static secrets and dynamically generated credentials for integrated systems.
Vault encrypts all data before writing to persistent storage backends. Even with direct access to the storage layer, secrets remain protected without Vault's encryption keys.
Dynamic secrets are credentials generated on-demand with automatic expiration. They reduce risk by eliminating long-lived credentials, providing time-bound access, and enabling automatic revocation when leases expire.
Yes, Vault provides HTTP APIs and client libraries for multiple programming languages. Applications can request secrets programmatically, and the vault-examples repository demonstrates integration patterns.
Vault supports multiple storage backends including local disk, Consul, and other systems. The choice of backend affects availability, scalability, and operational characteristics of your deployment.
