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.

Quotes from Members

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

Pros

"The most valuable feature of Elastic Security is that you can install agents, and they are not separately licensed."
"Elastic is straightforward, easy to integrate, and highly customizable."
"The most valuable feature is the ability to collect authentication information from service providers."
"It's not very complicated to install Elastic."
"The performance is good and it is faster than IBM QRadar."
"Its flexibility is most valuable. We can have a number of scenarios, and we can get logs from anything. If we know how to use Logstash, we can tweak it in many ways. This makes the logging search on Elastic very easy."
"It is scalable."
"The most valuable features of the solution are the prevention methods and the incident alerts."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"Its documentation should be a bit better. I have to spend at least a couple of hours to find the solution for a simple thing. When we buy Elastic, training is not included for free with Elastic. We have to pay extra for the training. They should include training in the price."
"It could use maybe a little more on the Linux side."
"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 problem with ELK is it's difficult to administer. When you have a problem, it can be very, very difficult to rebuild indexes."
"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."
"In terms of what could be improved with Elastic, in some use cases, especially on the advanced level, they are not ready made, so you'll have to write some scripts."
"There should be a simulation environment to check whether my Elastic implementation is functioning perfectly fine. Other solutions have their own Android and iOS applications that I can install on my mobile so that I am continuously connected to the SIEM."
"The solution could also use better dashboards. They need to be more graphical, more matrix-like."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"The price is reasonable. It probably costs the same as ArcSight and LogRhythm SIEM. FortiSIEM might cost less than Elastic Security. There are no hidden or additional costs."
"Affordable but with additional costs"
"We are using the free, open-source version of this solution."
"The product offers an amazing pricing structure. Price-wise, the product is very competitive."
"I can say that the product is cheaply priced."
"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."
"Compared to other tools, Elastic Security is a cheaper solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
