Laurentiu Popescu - PeerSpot reviewer
Cyber Security Lead at Orange
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.

Centralized security toolkit has simplified network traffic analysis and customized threat detection
The biggest advantage I found when using Security Onion was that it has a combined set of tools, which is beneficial, as having one place with multiple tools is advantageous. I have used Elastic Stack for data visualization, last using it maybe a couple of months back. Elastic Stack was helpful for my security operations as it is an open-source tool, allowing me to use multiple tools in one place instead of using them all separately. I have also tried Zeek, but I do not use it multiple times. I did not have enough time to understand if Zeek was effective or not, and I did not see much benefit from it. I find the intrusion detection capabilities of Suricata beneficial. With Suricata, we can write different rules for different signatures, which allows for customized use cases. It was helpful to aggregate all the events and traffic in one place with Security Onion, so it is beneficial.
