What is Azure Key Vault
Azure Key Vault is a Microsoft Azure service for centrally storing and controlling access to application secrets, encryption keys, and certificates. It is used by cloud and hybrid teams to reduce secret sprawl across code, configuration files, and deployment pipelines, and to support cryptographic operations backed by software or HSM-protected keys. The service integrates with Azure identity and access controls and provides APIs and SDKs for application and DevOps automation.
Deep Azure identity integration
Azure Key Vault integrates tightly with Microsoft Entra ID (Azure AD) for authentication and authorization. It supports role-based access control and policy-based permissions to separate duties across teams and environments. This reduces the need for application-managed credential stores when workloads already rely on Azure identity.
Supports keys, secrets, certificates
The service manages three common confidential asset types in one platform: secrets, cryptographic keys, and X.509 certificates. It supports key operations (such as signing and encryption) without exposing private key material to applications when using managed key operations. This breadth can simplify architectures compared with deploying separate tools for each asset type.
Automation and audit capabilities
Azure Key Vault provides REST APIs, SDKs, and integrations used in CI/CD and infrastructure-as-code workflows. It emits diagnostic logs that can be routed to Azure Monitor/Log Analytics for auditing and operational monitoring. These capabilities help teams standardize secret retrieval and track access patterns for compliance and incident response.
Azure-centric operational model
Key Vault is designed primarily for Azure-hosted workloads and Azure governance patterns. Multi-cloud or non-Azure-first environments may need additional tooling to standardize secret distribution and policy across platforms. This can increase operational complexity when compared with solutions built for heterogeneous environments.
Certificate lifecycle depth varies
While Key Vault can store and renew certificates (including via supported issuers and integrations), it is not a full certificate lifecycle management system for all enterprise PKI workflows. Advanced CLM needs—such as broad CA/PKI interoperability, complex approval processes, or large-scale discovery across diverse infrastructure—may require complementary tooling. Organizations with extensive internal PKI may find gaps relative to dedicated CLM platforms.
Service limits and cost factors
Throughput, API rate limits, and per-operation costs can become material for high-frequency secret retrieval or cryptographic operations. Some scenarios require careful caching, retry handling, and architecture choices to avoid latency and throttling impacts. HSM-backed options and logging/monitoring can also add cost and configuration overhead.
Plan & Pricing
| Plan | Price | Key features & notes |
|---|---|---|
| Standard (Vault) | $0.03 per 10,000 operations | Software-protected keys; secrets and most certificate/key operations billed per operation. Certificate renewal requests: $3.00 per renewal. (Operations = each authenticated REST API call). |
| Premium (Vault) | $0.30 per 10,000 operations (operations); HSM-protected keys incur additional per-key monthly charges (see HSM row) | Supports HSM-protected keys in addition to software-protected keys; operations billed per 10,000 calls as above; HSM keys incur per-key monthly fees and per-operation fees. |
| HSM-protected keys (Premium) | First 250 keys: $5.00 per key/month; 251–1,500 keys: $2.50 per key/month; 1,501–4,000 keys: $0.90 per key/month; 4,001+ keys: $0.40 per key/month; plus operations charged per 10,000 operations (see vault rows) | Only actively used HSM-protected keys (used in prior 30 days) are charged; each version of a key counts as a separate key for billing. |
| Managed HSM pools (Managed HSM) | Hourly usage fee per HSM pool — Standard B1: $3.20 per hour | Managed HSM is billed at an hourly pool rate (per HSM pool); key rotation and other Managed HSM features may have separate pricing/notes (see docs). |
