Direct effects for Operations**
Increased Alert Volume
The introduction of User-Based Alert Aggregation may lead to an increase in the volume of alerts generated, as alerts will be created per user and per rule, potentially overwhelming security teams if not prepared for the change.

Delayed Incident Response
Without proper preparation, the aggregation of alerts may delay incident response times, as security teams may need to sift through a higher volume of alerts to identify critical issues, impacting overall security posture.
