Here’re top AWS encryption servces KMS Vs. CloudHSM. Explained each service for your quick reference.

Managed Vs. Third Party Service
- Managed services are the practice of outsourcing the responsibility for maintaining, and anticipating the need for, a range of processes and functions in order to improve operations and cut expenses.
- It is an alternative to the break/fix or on-demand outsourcing model where the service provider performs on-demand services and bills the customer only for the work done.
2 AWS Encryption Services
- KMS (Key Managed Service & Managed by AWS)
- CloudHSM (Managed by third party not AWS)
AWS kms: Key Managed Service
It’s AWS managed service that makes it easy to create and manage encryption keys to encrypt your data across a wide range of AWS services and in your applications.
As a secure, resilient service, AWS KMS uses FIPS 140-2 validated cryptographic modules, known as a hardware security module (HSM), to protect your master keys.
The Federal Information Processing Standards (FIPS) is responsible for defining security requirements for cryptographic modules.
AWS Key Management Features
- Centralized key management
- Integration with other AWS services
- Audit capabilities
- High availability
- Custom key store
- It supports both Symmetric & Asymmetric encryption
AWS CloudHSM is third party service. It’s validated FIPS 140-2, level-three HSM. The HSM is a computing device that provides a dedicated infrastructure to support cryptographic operations.
CloudHSM supports encryption for your application while running in your own Amazon Virtual Private Cloud (Amazon VPC).
The Amazon Elastic Compute Cloud (Amazon EC2) instances can access the CloudHSM device quickly while isolating them from other networks.
The libraries include PKCS #11, Sun Java JCE (Java Cryptography Extension), and Cryptography API: Next Generation (CNG) providers for Microsoft. By using these libraries, you can perform cryptographic operations on the HSMs.
