SyedAli17 - PeerSpot reviewer
Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Cons

"It's a little bit of a learning curve to understand the logic of searching for things and trying to find what you're looking for in Elastic Security."
"Elastic Security can be a bit difficult to use if a person only has experience in SMBs with tools like Zoho. The product can also be difficult for those who have never dealt with query language."
