I worked for a telco client for the security model of Elastic, but my role was unit manager. I don't have a lot of technical expertise, but I decided on the solution for a client, and I was responsible for the delivery.
I worked with the security of the mobile app. I see all the logs in Elastic for SIEM. I monitored the logging and some logs from the machine for a UNIX system with some use cases like the machine's file system.
This solution is deployed on-premise.
We provide this solution to our customers, which are telcos, in the finance industry, and in retail.
I think that it's a good solution for a SIEM.
Elastic doesn't have the features like other competitors in SIEM. For example, Dynatrace as a solution for SIEM has features that Elastic actually don't have.
With Elastic, you have to build the use cases for the specific requirement. Other products have a simple integration and more use cases to integrate out-of-the-box solutions for SIEM. That's the improvement I would like to see.
Other products like Splunk are better than Elastic for a SIEM because there are some use cases already available for a client. Elastic doesn't have this, so the user must build the SIEM solution. I think that Elastic has to increase the features for the SIEM.
It's not very complicated to install Elastic, but I didn't deploy it.
I would rate this solution 7 out of 10.
It's a good solution and I would recommend it, but there are other products that have more features that Elastic doesn't have.
