Beyond HashiCorp Vault: OpenBao and Other Alternatives for Enterprise Secrets Management

For years, HashiCorp Vault has been one of the most widely adopted enterprise secrets management platforms. However, changes to Vault licensing, growing interest in open source governance, and evolving enterprise requirements have led many organizations to evaluate other options.

If you are researching HashiCorp Vault alternatives, the good news is that the ecosystem has matured significantly. Today, enterprises can choose from open source projects, cloud-native services, and SaaS-based platforms that offer robust capabilities for managing sensitive information.

This article explores Vault vs. OpenBao and other notable alternatives, along with the key considerations for selecting a secrets management platform that aligns with your organization's security and compliance goals.

Why Are Organizations Evaluating Alternatives to HashiCorp Vault?

Vault remains a powerful solution, particularly for organizations that require advanced secrets management, encryption services, and identity-based access controls. For most enterprise users deploying Vault internally, HashiCorp's licensing change does not affect day-to-day operations. However, it has introduced procurement, legal, and open source policy considerations that are prompting many teams to reassess their long-term secrets management strategy.

In August 2023, HashiCorp changed Vault from the Mozilla Public License 2.0 (MPL 2.0) to the Business Source License 1.1 (BUSL 1.1). BUSL 1.1 is not an OSI-approved open source license, and its key restriction prevents organizations from offering a competing commercial product or hosted service based on the Vault codebase. That distinction matters most for vendors, service providers, and organizations with formal open source governance requirements, but it has also made some enterprise legal and procurement teams more cautious when evaluating Vault.

IBM acquired HashiCorp, with the transaction closing in February 2025. Vault is currently offered as Vault Community Edition and Vault Enterprise. Vault Community Edition supports self-managed deployment, while Vault Enterprise is available for self-managed deployments and as the basis for HCP Vault Dedicated, HashiCorp's managed Vault service.

Several factors are driving evaluation of alternatives:

• Licensing and open source governance concerns
• Cloud lock-in considerations
• Operational complexity
• Enterprise feature costs
• Multi-cloud and hybrid cloud requirements

Organizations increasingly want flexibility in how they deploy, support, and govern their secrets infrastructure, especially when secrets management is tied to broader compliance, auditability, and long-term digital autonomy.

What to Look For in an Enterprise Secrets Management Platform

Before comparing products, it is important to define core requirements.

Secure Secret Storage

Any enterprise solution should provide encrypted storage for:

• Credentials
• API keys
• Certificates
• Tokens
• Encryption keys

Dynamic Secrets

Dynamic credentials reduce risk by generating short-lived secrets that expire automatically rather than relying on long-lived static credentials. Organizations with strong dynamic secrets requirements should look closely at how each platform handles on-demand credential generation, leasing, renewal, and revocation.

Fine-Grained Access Control

Organizations need policy-based access controls that integrate with identity providers and support least-privilege security models.

Auditability

Strong audit logging is increasingly important for compliance frameworks such as:

• ISO 27001
• SOC 2
• PCI DSS
• HIPAA
• NIS2
• DORA
• Cyber Resilience Act (CRA)

Automation and Integration

Secrets management should integrate with:

• Kubernetes
• CI/CD tooling
• Public cloud platforms
• Infrastructure as Code workflows
• Identity systems

Is OpenBao the Closest Open Source Alternative to Vault?

In short, yes. OpenBao has emerged as one of the most popular alternatives for organizations seeking a fully open source secrets management platform.

OpenBao is the community-driven fork of Vault's MPL 2.0-licensed codebase, with Vault 1.14.x being the last MPL-licensed release series. OpenBao is governed through an open source model and is designed to provide capabilities familiar to Vault users while meeting Open Source Initiative's definition of open source.

Key capabilities include:

• Secure secret storage
• Dynamic secret generation
• Identity-based access controls
• Certificate management
• Audit logging
• Data encryption services
• Secret leasing and revocation

OpenBao also supports dynamic secrets for systems such as databases and Kubernetes environments, allowing organizations to reduce reliance on static credentials.

Why Enterprises Are Interested in OpenBao

OpenBao appeals to organizations that:

• Prefer open governance
• Have open source procurement requirements
• Want to avoid vendor lock-in
• Need self-hosted secrets management
• Have existing Vault expertise

For organizations already operating Vault, OpenBao represents one of the lowest-friction migration paths among open source alternatives, subject to validation of specific feature requirements. Current OpenBao releases maintain a high degree of compatibility with Vault's core API and CLI for commonly used secrets engines and authentication methods, but organizations should validate compatibility against their specific feature set and targeted OpenBao version before migration.

That validation is important because Vault and OpenBao now evolve on independent roadmaps. Certain Vault Enterprise capabilities remain unavailable or may be implemented differently in OpenBao, and feature parity continues to evolve over time. Migration effort depends on the Vault deployment architecture, storage backend, plugins, and enterprise features in use. Teams should validate authentication methods, integrations, automation, operational procedures, and recovery processes before production cutover. 

OpenBao can be a lower-friction option for Vault-familiar teams, but it is not a zero-effort migration.

Other HashiCorp Vault Alternatives to Consider

Infisical

Infisical has gained attention as a developer-friendly secrets management platform focused on simplifying secret synchronization across applications, teams, and environments.

Infisical is available as both a self-hosted open source platform, with its core under the MIT license, and Infisical Cloud, a SaaS offering. Enterprise tier features include SAML SSO, SCIM provisioning, granular role-based access controls, secret versioning with point-in-time recovery, audit logging, approval workflows, and access request management.

Organizations often evaluate Infisical when:

• Developer experience is a priority
• Teams want easier onboarding
• Secret sharing across environments is a major challenge

Infisical maintains SOC 2 Type II certification, though organizations should verify current certification status and scope when evaluating specific compliance requirements. It integrates with tools and platforms such as GitHub Actions, GitLab CI, Jenkins, AWS, GCP, Azure, Kubernetes via External Secrets Operator, and a native Kubernetes operator.

Enterprises with strong dynamic secrets requirements should validate whether Infisical's current capabilities meet their needs in the edition being evaluated. Dynamic secrets are currently available in higher-tier commercial offerings and should be reviewed carefully, especially when compared with Vault and OpenBao, where database dynamic secrets are available in the community edition.

Azure Key Vault

For organizations heavily invested in Microsoft Azure, Azure Key Vault may provide a simpler operational model.

Benefits include:

• Native Azure integrations
• Azure identity management integration through Microsoft Entra ID
• Reduced infrastructure overhead
• Managed service capabilities

The tradeoff is that organizations may increase dependence on a single cloud ecosystem. Azure Key Vault is an Azure service and does not provide a provider-agnostic secrets engine for issuing dynamic credentials across AWS, Google Cloud, and arbitrary third-party systems. Cross-cloud architectures may require additional identity, automation, or integration mechanisms.

Azure Key Vault also differs from Vault-style dynamic secrets. It does not natively provide dynamic database credentials in the same model as the Vault database secrets engine. Key Vault supports automated secret-rotation workflows, but this is different from on-demand credential generation, leasing, and revocation.

For Azure-native workloads, Microsoft partially addresses credential reduction through Azure Managed Identities and Workload Identity for AKS, which can eliminate stored credentials by issuing short-lived tokens through Microsoft Entra ID. However, these are separate identity services rather than Key Vault dynamic-secrets features. They primarily address authentication to Microsoft and Azure resources and should not be treated as a general-purpose, multi-cloud dynamic-secrets engine.

Organizations evaluating Azure Key Vault as a Vault replacement should explicitly assess whether their workloads are entirely Azure-native, where Managed Identities may close part of the gap, or span multiple clouds and on-premises systems, where the absence of general-purpose dynamic secrets generation may remain a significant limitation. Azure Key Vault can serve hybrid environments through Azure Arc and service principals, but Azure connectivity is required, which may not suit air-gapped or strict on-premises environments. Azure Key Vault is available in Standard and Premium tiers, while Azure Managed HSM is a separate dedicated service for higher assurance requirements.

AWS Secrets Manager

AWS Secrets Manager is often a natural choice for organizations operating primarily within AWS.

Common advantages include:

• Tight integration with AWS services
• Managed operations
• Native IAM integration
• Simplified credential rotation

However, organizations pursuing multi-cloud strategies may prefer more platform-agnostic options.

Google Secret Manager

Google Cloud users often adopt Google Secret Manager to centralize credential and key management.

Potential benefits include:

• Native Google Cloud integration
• Centralized secret storage
• Managed scalability

However, as with other cloud-native options, organizations should evaluate portability to avoid potential cloud lock-in.

CyberArk Conjur

CyberArk Conjur focuses on securing machine identities, application credentials, and DevOps workflows.

CyberArk Conjur exists in two forms: Conjur Open Source, which is available on GitHub under an Apache 2.0 license, and CyberArk Secrets Manager, Self-Hosted, the commercially supported offering formerly known as Conjur Secrets Manager Enterprise. These editions differ materially in capabilities and support, so organizations should evaluate the specific edition that aligns with their requirements.

Within the CyberArk Identity Security Platform, Conjur is positioned for machine identity and DevSecOps use cases. This is distinct from CyberArk traditional privileged access management products, including CyberArk Enterprise Password Vault for human privileged accounts and CyberArk Endpoint Privilege Manager for endpoint privilege management.

Organizations often evaluate Conjur when:

• Privileged access management is already a strategic priority
• CyberArk technologies are already deployed
• Strong governance requirements exist

CyberArk provides the Secrets Provider for Kubernetes and a Conjur provider for the External Secrets Operator. CyberArk's Secrets Manager products focus primarily on secrets and non-human identities while integrating with the broader CyberArk Identity Security Platform. CyberArk solutions are commonly evaluated by organizations in regulated industries where governance, auditability, and vendor support are important requirements.

Final Thoughts

The conversation around HashiCorp Vault alternatives is no longer just about secrets management features. For many organizations, it now includes governance models, support strategy, vendor independence, compliance obligations, and long-term operational flexibility.

OpenBao has quickly become one of the most compelling options for enterprises seeking an open source alternative, particularly for teams that value community governance and want to maintain control over their secrets infrastructure. At the same time, cloud-native solutions and developer-focused platforms continue to expand the range of viable choices.

In 2026, the key is to evaluate secrets management as part of a broader security and regulatory strategy. Organizations should consider:

• Compliance requirements
• Deployment preferences
• Existing cloud investments
• Operational maturity
• Migration complexity
• Support requirements

The most successful implementations are those that balance security, operational efficiency, audit readiness, and the realities of enterprise-scale software delivery.

Frequently Asked Questions

What is the best open source alternative to HashiCorp Vault?

OpenBao is currently one of the most widely discussed open source alternatives because it was created as a community-led fork of Vault designed for enterprise secrets management while preserving an OSI-approved open source approach.

Is OpenBao compatible with HashiCorp Vault?

OpenBao was forked from Vault at approximately version 1.14.x. For core functionality including KV v1/v2, PKI, database dynamic secrets, Kubernetes auth, AppRole auth, AWS auth, and GCP auth, OpenBao is broadly API-compatible with Vault. CLI commands and API paths follow the same conventions as Vault OSS for commonly used workflows.

Organizations should still evaluate current feature compatibility and migration requirements based on their specific deployment. A practical migration checklist should include auditing all Vault secrets engines, auth methods, and plugins in use; verifying OpenBao support at the targeted version; testing automation such as Vault Agent, Terraform Vault provider, and Kubernetes Vault injector; confirming that required Vault Enterprise-specific capabilities are available and implemented equivalently; and validating handling of unseal keys, root tokens, storage backends, and recovery procedures based on the chosen migration approach.

Because Vault and OpenBao are independently maintained with separate release cycles, compatibility may diverge in particular areas over time. Teams should validate the specific versions and features being deployed before committing to a migration plan.

Why are organizations looking for HashiCorp Vault alternatives?

Common reasons include licensing preferences, open source governance requirements, cloud strategy considerations, operational complexity, cost management, and the need to align secrets management with compliance and digital sovereignty requirements.

Can cloud secret managers replace Vault?

For some organizations, yes. Enterprises operating primarily within a single cloud provider may find that Azure Key Vault, AWS Secrets Manager, or Google Secret Manager meet their requirements. Others may need broader multi-cloud or hybrid support, stronger portability, or Vault-style dynamic secrets across a wider range of systems.

What features should enterprises prioritize in secrets management?

Key capabilities include secure storage, dynamic secrets, identity-based access controls, audit logging, automation, integrations, compliance support, and a deployment model that aligns with the organization's cloud, hybrid, or on-premises requirements.
