AWS CloudHSM
AWS CloudHSM provides dedicated hardware security modules for storing cryptographic keys. It handles key generation, storage, and management within your own VPC, ensuring you retain full control over the hardware. This setup is essential for meeting strict regulatory compliance requirements without sharing infrastructure with other tenants.
It fits teams needing isolated, FIPS 140-2 Level 3 validated environments for sensitive data protection. The main trade-off is the lack of a free tier; you pay strictly on a pay-as-you-go basis, which adds cost for smaller projects or those just testing the waters.
