Which external data store can be used for external credential storage?

The correct answer, CyberArk, is recognized as a leading solution for external credential storage due to its focus on security and management of sensitive information, particularly passwords and API keys. CyberArk provides a robust vaulting mechanism that ensures these credentials are securely stored and accessed only by authorized users or services, enabling organizations to adhere to security compliance and risk management protocols effectively.

In contrast, while AWS, Microsoft Azure, and Google Cloud offer various services and functionalities around storage and management of resources, they are primarily cloud service platforms that have broader focuses, such as computing, networking, and application hosting. Although they may have credential management features within their ecosystems, CyberArk is specifically tailored for external credential management and vaulting, providing enhanced security practices and tools designed solely for the protection and management of sensitive credentials.
