Final answer:
SIEM license costs are usually based on the volume of data processed and the number of devices generating the logs. Additional factors like users, data stored, and feature requirements might also influence the cost.
Step-by-step explanation:
SIEM (Security Information and Event Management) license costs are typically calculated based on two primary factors: volume of data to be processed, which can be measured in events per second (EPS) or log message volume, and the number of devices or sources generating the security logs. In some cases, vendors may also offer pricing models based on factors such as the number of users, the volume of data stored, or advanced features required by the organization.
Furthermore, licensing models can differ, with some offering perpetual licenses and others providing a subscription-based model. It's crucial for organizations to consider these factors when budgeting for a SIEM solution to ensure they select a licensing model that aligns with their security needs and organizational structure.
