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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The scalability is good. It can be scaled easily in the production environment."
"The feature that we have found the most valuable is scalability."
"The solution's most valuable features are anomaly detection and connectivity reporting."
"It's very stable and reliable."
"It is very quick to react. I can set it to check anomalies or suspicious behavior every 30 seconds. It is very fast."
"The stability of the solution is good."
"The cost is reasonable. It's not overly pricey."
"I like that it's a SIEM platform. I like that I can sell Elastic Security quickly. Elastic Security has a large community that can support users."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"There is room for improvement in the Kibana dashboard and in the asset management for the program."
"There are connectors to gather logs for Windows PCs and Linux PCs, but if we have to get the logs from Syslog then we have to do it manually, and this should be automated."
"It would be better if Elastic Security had less storage for data. My customers do not like this. Other vendors have local support in different countries, but Elastic Security doesn't. I would like to have Operational Technology (OT) security in the next release."
"The solution's basic setup takes time, and a lot of effort is required from the beginning to make it actually work."
"We are paying dearly for the guy who is working on the ELK Stack. That knowledge is quite rare and hard to come by. For difficulty and availability of resources, I would rate it a five out of 10."
"The training that is offered for Elastic is in need of improvement because there is no depth to it."
"The initial configuration and setup are complicated and not straightforward."
"There isn't really a very good user experience. You need a lot of training."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"We are using the free, open-source version of this solution."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"I can say that the product is cheaply priced."
"The licensing cost of Elastic Security is based on the daily ingestion rate. I can't recall the exact figure, but for 10GB of log action daily, it would cost around $20,000."
"It is easy to deploy, easy to use, and you get everything you need to become operational with it, and have nothing further to pay unless you want the OLED plugin."
"Affordable but with additional costs"
"Its price is fine. Its licensing works on a yearly basis. We have to renew the license every year. I also have a good experience with Darktrace. 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."
"Security Onion is a free solution."
"It is an open-source solution."
"Security Onion is an open-source solution."
