Experience improves security management and simplifies threat protection
I have created automated investigations, and while they work, they operate rather slowly in the Microsoft portal. If I automate something, it takes considerable time; if I do it manually, I can complete it in a quarter of the time. The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation. There are some limitations regarding the scalability of Microsoft Defender XDR with specific licensing. For SMB customers, there is only Microsoft Defender for Business, and if they want more features such as XDR features and automation investigation or incident response, they need to purchase Defender for Endpoint. We are currently using the EDR.
John-Berry - PeerSpot reviewer
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.
