Featured Reviews

Laurentiu Popescu - PeerSpot reviewer
Chief Product Officer at ClusterPower
Has improved threat detection with deep log analysis and streamlined investigation workflows
The most useful features I find in Elastic Security are the forensic ones that allow us to carry deeper analysis into the logs for in-depth investigations, and the dashboards, with the reporting dashboard being quite user-friendly. Elastic Security is quite good at identifying threats, as it is part of the deep investigation tool that I mentioned before. Unless we need to look further into a certain log, we can carry out a deeper analysis and forensics on those particular logs. I can assess the impact of Elastic Security's real-time data analysis on our threat response efficiency as working pretty good. We are looking for real-time analysis because we have a continuous inflow of logs from different sources: from our cloud, from Active Directory, from our network. So it works pretty well.

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

"This solution helps us because we can find all of the logs in one place."
"The product in general has come very far and it's gotten a lot better over the years."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"The indexes allow you to get your results quickly. The filtering and log passing is the advantage of Logstash."
"I think that it's a good solution for a SIEM."
"Overall, this product does what it is supposed to do, although there is always room for improvement."
"The most valuable thing is that this solution is widely used for work management and research. It's easy to jump into the security use case with the same technology."
"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

"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."
"This solution cannot do predictive maintenance, so we have to build our own modules for doing it."
"Sometimes, the solution isn't the easiest to use."
"One thing they could add is a quick step to enable users who don't have a solid background to build a dashboard and quickly search, without difficulty."
"Installation is a little bit overwhelming, so improvements on the installation site could make it easier."
"The training that is offered for Elastic is in need of improvement because there is no depth to it."
"One thing they could add is a quick step to enable users who don't have a solid background to build a dashboard and quickly search, without difficulty."
"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."
"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

"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."
"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"I can say that the product is cheaply priced."
"We are using the free, open-source version of this solution."
"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."
"There is no charge for using the open-source version."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
