Has improved threat detection with deep log analysis and streamlined investigation workflows

The most useful features I find in Elastic Security are the forensic ones that allow us to carry deeper analysis into the logs for in-depth investigations, and the dashboards, with the reporting dashboard being quite user-friendly. Elastic Security is quite good at identifying threats, as it is part of the deep investigation tool that I mentioned before. Unless we need to look further into a certain log, we can carry out a deeper analysis and forensics on those particular logs. I can assess the impact of Elastic Security's real-time data analysis on our threat response efficiency as working pretty good. We are looking for real-time analysis because we have a continuous inflow of logs from different sources: from our cloud, from Active Directory, from our network. So it works pretty well.

"The biggest challenge has been related to the implementation."

"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."

"They don't provide user authentication and authorisation features (Shield) as a part of their open-source version."

"One limitation of Elastic Security is that it does not have built-in workflows for all tasks. For example, if you need a workflow for compliance, you will need to create a custom workflow."

"It is difficult to anticipate and understand the space utilization, so more clarity there would be great."

"In terms of improvement, there could be more automation in responding to and evaluating detections."

More Elastic Security cons

When we buy Darktrace, we get training free of cost, which is not there in Elastic. We have to pay extra for training. There is certainly room for improvement."

"We are using the free, open-source version of this solution."
