SyedAli17 - PeerSpot reviewer
Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) 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

"I can look at events from more than one source across multiple different locations and find patterns or anomalies. The machine learning capabilities are helpful, and I can create rules for notifications to be more proactive rather than responding after something has gone wrong."
"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."
"I use the stack every morning to check the errors and it's just so clear. I don't see any disadvantage to using Logstash."
"Enables monitoring of application performance and the ability to predict behaviors."
"Elastic Security is very customizable, and the dashboards are very easy to build."
"The most valuable feature is the speed, as it responds in a very short time."
"The visualization is very good."
"It's simple and easy to use."
"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"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 solution's query building is not that intuitive compared to other solutions."
"Elastic Security could improve the documentation. It would help if they were more simple and clean."
"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."
"We're using the open-source edition, for now, I think maybe they can allow their OLED plugin to be open source, as at the moment it is commercialised."
"Email notification should be done the same way as Logentries does it."
"There is an area of improvement in the Logs list. The load list may need to be paginated as there are limits."
"The tool should improve its scalability."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
 

Pricing and Cost Advice

"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."
"We are using the free, open-source version of this solution."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"We use the open-source version, so there is no charge for this solution."
"The base product is open-source but if you need advanced security features then you need to pay for the subscription. Elastic Security's price is reasonable in some cases and in other cases it's not."
"The solution is not expensive and costs around ten dollars a month."
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"This is an open-source product, so there are no costs."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
