Stand-alone FIM software usually provides ready integrations with those solutions.

On-premises vs Cloud-based Installations: When appropriate for your environment cloud-based FIM solutions offer global reach, simplify implementation, and reduce the need for multiple point product installations and their potentially higher costs.

Platforms: Some FIM products can be installed on and support multiple operating systems, others will only support Windows or Linux/Unix.

Scalability: Depending on the size of your IT infrastructure, FIM can create a large amount of information to be reviewed. For enterprise-scale monitoring, your selection should provide the ability to narrow its focus to essential resources and critical updates.
