Featured Reviews

Gajewski Marek - PeerSpot reviewer
Provides good anomaly detection and connectivity reporting
We previously used Splunk but switched to Elastic Security because Splunk was more expensive. Feature-wise, both tools are pretty much the same. They have almost the same functions. Elastic Security has a much better AI assistant that allows you to ask questions like a normal person. With Elastic Security, I can also predict the price and how much it will cost. Splunks's pricing depends on how much data we use and the different add-ons I have to add. The pricing is much better with Elastic Security.
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 performance is good and it is faster than IBM QRadar."
"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."
"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 very quick to react. I can set it to check anomalies or suspicious behavior every 30 seconds. It is very fast."
"The most valuable feature is the search function, which allows me to go directly to the target to see the specific line a customer is searching for."
"It's a good platform and the very best in the current market. We looked at the Forester report from December 2022 where it was said to be a leader."
"It is the best open-source product for people working in SO, managing and analyzing logs."
"ELK documentation is very good, so never needed to contact technical support."
"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."
"Security Onion is the most mature solution in the market."
 

Cons

"The price of this product could be improved, especially the additional costs. I would also like to see better-quality graphics."
"The solution's query building is not that intuitive compared to other solutions."
"Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana."
"The tool needs to integrate with legacy servers. Big companies can have legacy servers that may not always be updated."
"I would like more ways to manage permissions and restrict access to certain users."
"The solution could offer better reporting features."
"The solution needs to be more reactive to investigations. We need to be able to detect and prevent any attacks before it can damage our infrastructure. Currently, this solution doesn't offer that."
"We'd like to see some more artificial intelligence capabilities."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"Compared to other products such as Dynatrace, this is one of the cheaper options."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"We use the open-source version, so there is no charge for this solution."
"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."
"The product offers an amazing pricing structure. Price-wise, the product is very competitive."
"When compared to other products, the price is average or on the low side."
"I can say that the product is cheaply priced."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"Security Onion is an open-source solution."
"It is an open-source solution."
"Security Onion is a free solution."
