The advantage of on premise credential management systems is that they provide more control over the system configuration and customization. On premise credential management systems are the systems that store and manage the credentials, such as usernames, passwords, tokens, or certificates, of the users or the devices within an organization’s own network or infrastructure. On premise credential management systems can offer more flexibility and security for the organization, as they can tailor the system to their specific needs and requirements, and they can enforce their own policies and standards for the credential management.
A. Improved credential interoperability is not an advantage of on premise credential management systems, but rather an advantage of cloud-based credential management systems. Cloud-based credential management systems are the systems that store and manage the credentials of the users or the devices on a third-party cloud service provider’s network or infrastructure. Cloud-based credential management systems can offer more interoperability and scalability for the organization, as they can support different types of credentials and devices, and they can adjust to the changing demand and workload of the credential management.
C. Lower infrastructure capital costs is not an advantage of on premise credential management systems, but rather an advantage of cloud-based credential management systems. Cloud-based credential management systems can reduce the infrastructure capital costs for the organization, as they do not require the organization to purchase, install, or maintain their own hardware or software for the credential management. Instead, the organization can pay a subscription fee or a usage fee to the cloud service provider for the credential management service.
D. Reduced administrative overhead is not an advantage of on premise credential management systems, but rather an advantage of cloud-based credential management systems. Cloud-based credential management systems can reduce the administrative overhead for the organization, as they do not require the organization to perform the tasks or the functions related to the credential management, such as backup, recovery, patching, or updating. Instead, the cloud service provider can handle these tasks or functions for the organization, as part of the credential management service.
