Use Cases and Deployment Scope
LogRhythm is a great SIEM with many needed features and competitive pricing. They also offer both on-premises and cloud solutions based on your needs. They have a decent community and support. They offer many needed features, such as UBEA, NDR, and file monitoring. Their web console is well-designed, while I can't say the same for their client console.
