The SOC center monitors, hunts, and notifies us of threats around the clock
I know they are working to resolve this issue, but Netsurion is currently unable to retrieve logs from S3 buckets. We use WP Engine for a lot of web hosting as well as AWS, and both of these platforms use S3 buckets. I would like Netsurion to be able to pull logs from Linux devices. We have some of that capability, and I believe they can do it. However, the way it works with Amazon is strange and glitchy. Therefore, working something out with Amazon would be great. Netsurion's SOC can be a bit too aggressive at times. We have asked them to adjust their playbook because I am tired of being notified about the same issue multiple times a day. I am aware of the issue, and it is not a cause for concern. Let's only take action on this issue if we see an actual problem.

Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.
