Key Takeaways
- Azure Key Vault is a strong choice for teams fully committed to Azure that want a managed service with no infrastructure to run, but it doesn’t extend past Azure and offers limited dynamic secrets.
- HashiCorp Vault is the cloud-agnostic option with deeper dynamic-secrets support, but it’s self-hosted by default, requires cluster and upgrade maintenance, and moved off open source to a Business Source License in 2023.
- Both tools solve secrets storage well; neither solves multi-cloud governance or removes the operational cost of running or licensing the platform itself.
- Akeyless is a fully managed SaaS platform that works across Azure, AWS, GCP, and on-prem from one control plane, and it connects to an existing Azure Key Vault or HashiCorp Vault deployment instead of requiring a full migration.
- Cimpress replaced HashiCorp Vault with Akeyless and cut total cost of ownership by 70%, citing Akeyless’s platform approach and service quality as the reason.
Quick Answer: Should You Choose Azure Key Vault or HashiCorp Vault?
Azure Key Vault fits teams that are all-in on Azure and want zero infrastructure to manage, at the cost of being locked to one cloud with limited dynamic-secrets support. HashiCorp Vault fits teams that need multi-cloud flexibility and advanced secrets engines and are willing to run the infrastructure themselves, under a license that’s no longer fully open source. Teams that want multi-cloud coverage without either tradeoff are increasingly looking at fully managed alternatives like Akeyless, which can also govern secrets that stay inside an existing Azure Key Vault or Vault deployment.
- Azure Key Vault: managed, Azure-only, limited dynamic secrets, pay-per-operation pricing.
- HashiCorp Vault: self-hosted (or HCP-managed), multi-cloud, deep dynamic-secrets support but operationally heavy, BSL-licensed since 2023.
- Akeyless: fully managed SaaS, multi-cloud from day one, zero-knowledge encryption, connects to existing Vault or Key Vault deployments instead of requiring rip-and-replace.

Someone comparing Azure Key Vault and HashiCorp Vault picks between two different tradeoffs. Azure Key Vault offers a fully managed, single-cloud service. HashiCorp Vault offers a self-hosted, multi-cloud tool with deeper dynamic-secrets support. The right pick depends on how committed the organization already is to Azure, and how much infrastructure it’s willing to run.
Both tools solve secrets storage well. Neither one solves the tradeoff that comes with picking it. Azure Key Vault ties a team to a single cloud. HashiCorp Vault hands a team its own infrastructure to run and maintain. Neither tradeoff disappears once a team picks a side, and it matters more than most feature comparisons suggest.
This piece compares Azure Key Vault vs HashiCorp Vault across features, architecture, pricing, and licensing. It also covers a third option: Akeyless, a fully managed platform that runs across every major cloud from one control plane. Akeyless also connects to an existing Azure Key Vault or HashiCorp Vault deployment, so adopting it doesn’t require a full migration.
What Is Azure Key Vault?
Azure Key Vault is Microsoft’s fully managed secrets, key, and certificate store. It’s built to work natively inside the Azure ecosystem, with no infrastructure for the customer to run. It stores three types of objects: cryptographic keys, secrets such as passwords and connection strings, and TLS certificates purchased from a public certificate authority. Secrets are capped at 2510 KB each (Microsoft, Azure Key Vault).
The service ships in two tiers. The Standard tier protects keys in software. The Premium tier backs keys with a hardware security module, the stronger option for regulated workloads. Both tiers bill per 10,000 operations against keys, secrets, and certificates, with a separate monthly fee for each HSM-protected key (Microsoft, Key Vault pricing).
Access runs through Microsoft Entra ID (formerly Azure Active Directory) and role-based access control. Key Vault permissions follow the same identity system already governing the rest of an Azure subscription. The Entra ID integration is Key Vault’s biggest strength for a team already standardized on Azure, and its biggest limit for a team that isn’t.
What Is HashiCorp Vault?
HashiCorp Vault is a self-hosted (or HCP-managed) secrets and encryption platform built for multi-cloud and on-prem environments. Dynamic secrets and a broad plugin ecosystem are its core strengths. Vault centers on three components: secrets engines, authentication methods, and policies (HashiCorp, Vault). IBM completed its acquisition of HashiCorp in February 2025, for roughly $6.4 billion, which is why Vault’s current pricing is now published under a joint IBM/HashiCorp page.
Secrets engines cover static key-value storage and encryption-as-a-service through Vault’s transit engine. They also generate dynamic secrets: temporary database and cloud credentials created on demand. Authentication methods verify humans and machines before granting a token, and policies scope exactly what that token can reach.
Teams run Vault two ways: self-hosted (Vault Enterprise, on the team’s own infrastructure) or as HCP Vault Dedicated, HashiCorp’s managed offering. Both options require standing up separate clusters per region for disaster recovery and performance replication, which is where Vault’s operational cost tends to show up (IBM/HashiCorp pricing). A lighter, fully-SaaS tier called HCP Vault Secrets existed for a time but has since been retired: it stopped accepting new customers in mid-2025 and is being wound down for remaining customers, with HashiCorp steering everyone toward HCP Vault Dedicated instead.
Licensing changed in August 2023. HashiCorp moved Vault from the Mozilla Public License 2.0 to the Business Source License, ending its run as a fully open-source project. End users can still copy, modify, and self-host the code for both commercial and non-commercial use. The one restriction: a vendor can’t build a competing commercial offering on top of it (HashiCorp’s own announcement).
Azure Key Vault vs HashiCorp Vault: Features and Architecture Compared
| Category | Azure Key Vault | HashiCorp Vault |
| Secrets storage | Keys, secrets, and certificates; secrets capped at 2510 KB | Key-value secrets, certificates, and encryption-as-a-service |
| Dynamic secrets | Limited; mainly static keys and secrets | Native, with database, cloud, and PKI engines that issue temporary credentials |
| Access control | Microsoft Entra ID and role-based access control, inherited from the Azure subscription | Path-based policies tied to Vault’s own authentication methods |
| Deployment | Fully managed by Microsoft; no infrastructure to run | Self-hosted (Vault Enterprise) or HashiCorp-managed (HCP Vault Dedicated); clusters required per region for HA |
| Cloud reach | Azure only | Any cloud or on-prem environment |
| Audit and compliance | Logs stream to Azure Monitor; compliance inherited from the Azure subscription | Detailed audit logging built in; compliance posture depends on how the cluster is deployed and secured |
Azure Key Vault and HashiCorp Vault solve different problems well. Azure Key Vault wins on simplicity for a single-cloud team: no clusters, no patching, and access control that’s already familiar to anyone using Azure. HashiCorp Vault wins on reach and depth: it works anywhere, and its dynamic secrets engine covers far more systems than Key Vault’s static model. The tradeoff is architectural, not a matter of one tool having more features than the other.
Azure Key Vault vs HashiCorp Vault: Pricing and Licensing Compared
Azure Key Vault and HashiCorp Vault price and license access to their platforms in fundamentally different ways. The difference often matters more to a buyer than any single feature comparison. Azure Key Vault uses a consumption model: Microsoft bills per 10,000 operations, plus a separate per-key fee for HSM-backed keys. There’s no flat monthly rate, so cost scales directly with usage (Microsoft, Key Vault pricing).
HashiCorp Vault prices differently depending on how a team deploys it. IBM’s HCP Vault Dedicated costs $72.92 per client per month. Hourly cluster fees add on top, ranging from $0.62 for an extra-small development cluster to $9.41 for a large cluster. Vault Radar, HashiCorp’s separate secret-sprawl scanner, costs $7 per active user per month (IBM/HashiCorp pricing).
Self-hosted Vault Enterprise works differently. A team pays for its own hardware and licensing instead of HashiCorp’s managed fees. Every region also needs its own cluster for disaster recovery and performance replication.
The Business Source License shift changes what a team can do with Vault, not what it costs to run it. Vault Community Edition stays free to self-host. The enterprise features Vault needs for production useThe enterprise features that make Vault viable at scale (HSM support, disaster recovery, advanced access controls) sit behind the paid tiers, regardless of license type.
The Tradeoff Neither Tool Solves
Azure Key Vault locks a team into a single cloud. HashiCorp Vault locks a team into managing its own infrastructure. Switching from one to the other just trades one constraint for another. A team that outgrows Azure Key Vault because it’s expanding to AWS or GCP doesn’t get relief from HashiCorp Vault. It gets a different problem: standing up and maintaining clusters, replication, and upgrades across every region it operates in.
Neither vendor advertises a zero-knowledge encryption model on its own product pages. Both are conventional custodial architectures, where the platform itself can reach the underlying keys under the right conditions (Microsoft’s and HashiCorp’s own documentation). Neither vendor treats the custodial model as a flaw to fix. It’s a structural feature of how both were built, and it’s worth knowing before committing to either one.
Where Akeyless Fits as a Managed Alternative to Both
The Challenge
A multi-cloud organization either accepts Azure Key Vault’s single-cloud ceiling or takes on HashiCorp Vault’s self-hosted maintenance burden. Neither tool offers a managed path across more than one cloud.
The Approach
Akeyless runs as a fully managed SaaS platform across AWS, Azure, GCP, and on-prem environments from one control plane.
Akeyless protects secrets with Distributed Fragments Cryptography, a zero-knowledge encryption model. The model splits keys into fragments, so no single party, including Akeyless itself, can reconstruct one alone (Akeyless, Secrets Management).
Akeyless also connects natively to an existing Azure Key Vault or HashiCorp Vault through Multi-Vault Governance, priced per Key Vault and per Vault instance (Akeyless, pricing units). Adopting Akeyless this way doesn’t require ripping out either tool first.
The Outcome
The connector-first approach gives a team two paths, not one forced migration. Cimpress took the full-replacement path, moving off HashiCorp Vault entirely.
Daniel Fabbo, Senior Manager of Information Security at Cimpress, described the decision directly: “Akeyless’ platform approach, superb technology and service excellence made it easy for us to decide to rip and replace Hashi Vault” (Akeyless, HashiCorp Vault Alternative).
Cimpress cut total cost of ownership by 70% and raised platform adoption 270% compared to its previous provider (Akeyless, Cimpress case study). A team that isn’t ready to fully migrate off Azure Key Vault can take the second path instead. It connects Akeyless to the existing deployment and governs those secrets alongside everything else on one platform.
How Do You Choose Between Azure Key Vault, HashiCorp Vault, and Akeyless?
The right choice depends on how many clouds the organization actually runs in and how much infrastructure it wants to own. It doesn’t depend on which tool has the longer feature list. A single-cloud team fully committed to Azure, with no near-term multi-cloud plans, is the best fit for Azure Key Vault’s zero-infrastructure model.
A multi-cloud team with in-house platform engineering capacity and an appetite for running its own clusters is the best fit for Vault. It gets Vault’s depth and flexibility in exchange for that operational investment.
A multi-cloud team without that appetite is the clearest fit for Akeyless. The same goes for a team already invested in Azure Key Vault or HashiCorp Vault that isn’t ready to migrate. Its native connectors mean adoption doesn’t require a rebuild before governance improves.
FAQs
Does Akeyless Require Replacing an Existing Azure Key Vault or HashiCorp Vault Deployment?
No. Akeyless’s Multi-Vault Governance connectors sync and manage secrets stored in an existing Azure Key Vault or HashiCorp Vault instance directly (Akeyless, pricing units). They don’t require a migration first. A team can adopt Akeyless as a governance layer over what it already runs, then decide later whether to migrate fully. Cimpress later migrated fully off HashiCorp Vault this way.
Is HashiCorp Vault Still Open Source?
Not fully. HashiCorp moved Vault from the Mozilla Public License 2.0 to the Business Source License in August 2023. Vault Community Edition remains free to self-host and modify for both commercial and non-commercial use. The license only restricts one thing: building a competing commercial product on top of it (HashiCorp’s own announcement).
Can Azure Key Vault Be Used Wwith AWS or Google Cloud Workloads?
Not natively. Azure Key Vault is built to work inside the Azure ecosystem, with access control tied to Microsoft Entra ID. A workload running in AWS or GCP would need custom integration work to reach it, which is the exact single-cloud ceiling this piece covers.
How Does Zero-Knowledge Encryption Differ Ffrom How Azure Key Vault or HashiCorp Vault Protect Secrets?
Azure Key Vault and HashiCorp Vault both use conventional custodial architectures. The platforms themselves hold or can reach the encryption keys under the right conditions. Zero-knowledge encryption splits a key into fragments across separate locations, so no single party, including the vendor, can reconstruct the complete key alone. Akeyless uses this model through Distributed Fragments Cryptography; neither Azure Key Vault nor HashiCorp Vault advertises an equivalent architecture on its own product pages.
Does Moving to a SaaS Platform Mean Losing Access to HashiCorp Vault’s Plugin Ecosystem?
Not if the migration happens through a connector instead of a full rebuild. Akeyless’s HashiCorp Vault connector governs secrets that stay inside an existing Vault deployment. A team can keep using Vault’s engines and plugins while adding centralized policy and audit on top. A full migration, like Cimpress’s, replaces Vault’s engines with Akeyless’s own equivalents instead.
What Happens to Azure Key Vault or HashiCorp Vault Access Policies During a Migration to Akeyless?
Existing access policies stay in place until a team explicitly changes them. Akeyless’s connectors read from the existing vault without altering its configuration. A full migration works differently: it involves rebuilding access policies under Akeyless’s own role-based access model rather than inheriting them automatically.
