Enhances our security incident investigation but not good for correlation

Investigation is good when you know what you want to search for in Logger. The most difficult part is parsing the logs and configuring the parsers. For investigation, it's good. For correlation, it's not good. We use Sentinel, and Sentinel has pre-built use cases that are much easier to configure. So, it enhances our security incident investigation. We have inbound integration, but configuring the parsers is sometimes very difficult. We only have two use cases where we have a correlation set up. We send the information to Check Point to block IP addresses when we see a lot of blocks from the same source. We have a trigger. So, Logger automatically blocks these IP addresses. We could have Logger put them on a blacklist. So, it offers the ease of integration.

Cons

"I think the ArcSight team should try to simplify legacy products for the customers, because that product is not easy to use or to work with. It needs more more competency or appeal to use. We hope Micro Focus is trying to resolve this."
