Vault is a secrets management and data protection platform created by HashiCorp, designed to securely store, access, and control sensitive data such as API keys, passwords, certificates, and encryption keys across applications and infrastructure. It centralizes secret distribution through fine-grained access policies and strong authentication, supports encryption-as-a-service via its Transit engine, and can issue dynamic, short-lived credentials for systems like databases and cloud providers to reduce long-term credential exposure. Vault also provides auditing, leasing and renewal of secrets, and multiple storage backends and high-availability configurations for resilient operations, with common deployment patterns including running Vault on Kubernetes for automated scaling and integration with modern platform workflows.
Secrets management is the practice of securely storing, managing, and using sensitive information, such as passwords, API keys, and certificates. This is important because sensitive information is often required for accessing critical systems and services, and if it is not properly protected, it can be vulnerable to being stolen or misused.
There are several reasons why secrets management is crucial:
Vault is a secrets management and encryption platform used to protect sensitive values like API keys, database credentials, tokens, and certificates. It is typically adopted to reduce secret sprawl, enforce consistent access policies, and enable short-lived credentials across cloud and Kubernetes environments.
Vault is a strong fit for platforms that need centralized governance and dynamic credentials across multiple runtimes. It does add operational considerations such as unseal and key management, storage backend selection, and HA design, so it benefits from automation and well-tested runbooks.
Common alternatives include AWS Secrets Manager, Azure Key Vault, Google Secret Manager, and CyberArk Conjur. For product details, see the official HashiCorp Vault documentation.
Our experience with Vault has helped us build practical knowledge, repeatable runbooks, and automation that make it easier for clients to adopt best practices and operate Vault safely at scale.
