Each secret stored with Vault uses a unique encryption key and is cryptographically isolated based on user-provided context. Envelope encryption enhances security by encrypting data with a data encryption key (DEK), which is then encrypted with a key encryption key (KEK). This approach ensures sensitive data remains protected while allowing secure key management and access control.

The Enterprise Key Management features of Vault centralize control over encryption keys used for customer data in multi-tenant architectures. It streamlines key lifecycle management, access policies, and auditability while integrating seamlessly with your existing applications. Key segmentation by organization, user, or any provided context ensures cryptographic keys are isolated, reducing risk and enforcing access control at boundaries that make sense for your business.

With Vault you can provide keys either from your own environment or directly linked to your customers’ cloud environments. BYOK gives you full control over encryption keys while integrating seamlessly with your own security tooling such as cloud SIEMs. It ensures your keys stay protected in your custody while enabling secure access for encryption operations, perfect for compliance-driven workloads. BYOK integration is available for many popular key management services, including Amazon Web Service KMS, Google Cloud Compute KMS, Azure Key Vault, and HashiCorp Vault.

Sensitive data in a B2B application is often linked to specific organization. This can be shared secrets, API keys, OAuth credentials, or even data generated by your application. Vault protects this information and easily links each secret with the organization it belongs to in order to provide full cryptographic separation from other organizations within your application.

User data such as Personally Identifiable Information (PII) or Protected Health Information (PHI) is highly sensitive and can have strict regulatory requirements including strong encryption, access controls, and data minimization. The risk for mishandling this data is very high – both financially and reputationally. Vault lets you store this data using unique encryption keys without needing to manage the complex lifecycle of key hierarchies.

With short-lived dynamic workloads in the cloud, static credentials represent a huge security risk. Secrets can get spread out across many services, making rotation difficult and the change of a leak high. Vault can encrypt and store application data such as API keys, database credentials, and PKI certificates in a centralized service and provide them to your application at runtime.
