Which AWS service offers managed hardware security modules?

AWS CloudHSM is designed specifically for providing managed hardware security modules (HSMs). This service allows users to generate and use their own encryption keys in a secure environment, maintaining control over the keys and the cryptographic operations performed with them. By handling the complexities associated with the management of HSM infrastructure, AWS CloudHSM enables organizations to meet stringent security and compliance requirements, such as those mandated by regulations like PCI DSS or GDPR.

With CloudHSM, users can leverage isolated, managed HSMs in the AWS cloud, which are beneficial for applications requiring high levels of security for key management. The service is seamlessly integrated with various AWS services, making it suitable for enterprises that need to encrypt sensitive data while maintaining control over their cryptographic keys.

In contrast, while AWS Key Management Service (KMS) also supports key management, it is not specifically focused on hardware security modules, as it operates primarily on a software-based approach to key management. Amazon Macie is a data security and privacy service that uses machine learning to automatically discover, classify, and protect sensitive data, rather than focusing on hardware security. Lastly, Amazon Cognito is primarily used for user authentication and access control, which does not involve managed HSMs either. Therefore
