Azure Key Vault vs HashiCorp Vault comparison

Microsoft Azure Key Vault is a cloud-based data security and storage service that allows users to keep their secrets safe from bad actors.

Benefits of Microsoft Azure Key Vault

Some of the benefits of using Microsoft Azure Key Vault include:

• Secure your secrets in a single central location, enabling you to control how your information is disseminated.

• Keep your data away from bad actors. Application administrators can store their application’s security information away from the actual application. Microsoft Azure Key Vault reduces the chance that a bad actor will be able to leak an application’s secrets. Because the data is not stored in the code of the application, hackers will be unable to steal the security information.

• Retrieve your information securely. When the information is needed, the application can securely retrieve it by using a uniform resource identifier (URI) to connect to Microsoft Azure Key Vault.

• Securely store your digital keys and secrets. Microsoft Azure Key Vault stores data behind layers of security protocol. No one can access the information stored in a Microsoft Azure Key Vault without first obtaining the necessary authentication and authorization. The authentication process allows the system to figure out who is trying to access the vault in question. This process is performed by Azure’s Active Directory. After the person or entity is authenticated, Microsoft Azure Key Vault then assigns them a level of authorization. This determines what sort of actions they will be able to perform.

• Choose from two different authorization options. The level of a user’s authorization can be either role-based or dictated by a policy that the administrator sets. Azure’s role-based access control (Azure RBAC) enables users to both manage and access stored data. A key vault access policy limits users to data access.

• Secure your data in the way that best fits your needs. Your data can be protected by either industry-standard algorithm software or hardware security modules (HSMs). Your data is even safe from Microsoft, as the vaults are designed so that not even Microsoft can get in and access the information.

• Easily monitor who accesses your vault(s). Microsoft Azure Key Vault enables administrators to keep a close eye on their secrets. Users can activate a vault-logging feature that will track every piece of information. It will record who accessed the vault, when they accessed it, and other pertinent details.

• Choose how you want to store your logs. Users can store logs in multiple ways. These logs can be archived, sent to the Azure monitor logs area, or streamed to an events hub. The logs can be secured to prevent unauthorized viewing and deleted when they are no longer needed.

Reviews from Real Users

Microsoft Azure Key Vault stands out among their competitors for a number of reasons. Two major ones are the overall robustness of the solution and its ability to protect and manage many different digital asset types. The many features that the solution offers allows users to tailor their experience to meet their specific needs. Its flexibility enables users to accomplish a wide variety of security and identity management related tasks. It empowers users to secure a wide array of assets. Users can keep many different types of secrets away from bad actors.

A cloud architect at a marketing services firm writes, “All its features are really valuable. It's really well thought-out. It's a complete turnkey solution that has all the concerns taken care of, such as access control and management. You can use it in infrastructure as code to create key vaults, APIs, PowerShells, CLIs, even Terraform. You can also use it in different services across the board. If you have app services, or virtual machines, Kubernetes, or Databricks, they can all use Key Vault effectively. In my opinion, in a DevSecOps, DevOps, or even in a modern Azure implementation, you have to use Azure Key Vault to make sure you're addressing security and identity management concerns. By "identity" I mean usernames, passwords, cryptography, etcetera. It's a full-blown solution and it supports most breeds of key management: how you store keys and certify.”

Roger L., the managing director of Cybersecurity Architecture at Peloton Systems, says, “The most valuable aspect of the product is its ability to keep our admin password accounts for keys and a lot of our high-value assets. It can manage those types of assets. So far, the product does a great job of managing keys.”

HashiCorp Vault is a cloud-agnostic solution used for security and secret management. Its valuable features include integration with other HashiCorp tools, token sharing, open source nature, cloud agnosticism, and on-the-fly encryption management. 

The solution provides encryption of data at rest, in use, in transit, on the fly, and linked with applications. It is free to use, and the interface is simple to navigate. HashiCorp Vault has helped organizations with its multiple authentication methods and RESTful API.

HashiCorp Vault Features

• Data encryption: The solution is capable of encrypting and decrypting data, and will not store it. Organizations’ security personnel define their own encryption protocols; developers can store the encrypted data where they choose and are not obligated to design specific encryption processes.
  
  
• Robust secrets: For systems such as AWS or SQL databases, Vault is able to generate secrets automatically. HashiCorp Vault is able to generate AWS keypairs with all the appropriate permissions when necessary, and when the approved time expires, will nullify them.
  
  
• Secure secret storage: Any type of value or key secrets can be stored in the Vault. The Vault automatically encrypts the desired secrets before recording them into persistent storage, keeping them safe and secure. Users can record data using HCP Vault’s Consul service or disk, or choose from other options.
  
  
• Nullification: Vault is able to nullify single secrets or all secrets from a particular group or specific user. This process is integral in securing systems in the event of an attack or inappropriate access.

“The greatest benefit of HashiCorp is its ability to manage encryption on the fly. It provides encryption of data at rest, in use, in transit, on the fly, and linked with applications, which was really attractive. The lifecycle of a key is so easy to manage in terms of rotating, revoking, and issuing. They have different auth methods, and I tried all different auth methods. It is seamless.”- Project Manager at a comms service provider.

“The most valuable feature of HashiCorp Vault is that it's an open source solution. Second, it's cloud-agnostic, so it's very easy to maintain and control, which is why we prefer HashiCorp. “ - Mohamed A., Lead DevOps Engineer at Etisalat.
