HashiCorp Vault is a popular platform for providing cryptographic services centrally, standardizing cryptographic tools, reducing the total cost of ownership, and making auditing easier. By centralizing encryption tools in a self-service platform, developers can lower their cost of ownership, follow best practices, and make auditing more efficient. The solution involves delivering encryption as a service (EaaS), where security architects manage centralized policy-driven cryptographic services that enforce corporate governance and security standards. This approach enables developers to focus on writing domain code without worrying about cryptography, reduces the risk of exposure for cryptographic keys, and simplifies key management and maintenance. Additionally, it makes modern cryptography available to legacy platforms and runtimes, reducing the cost of maintaining cryptographic standards in the enterprise.
