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

"The product in general has come very far and it's gotten a lot better over the years."
"The most valuable features are the speed, detail, and visualization."
"The solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."
"It's simple and easy to use."
"The most valuable features of the solution are the prevention methods and the incident alerts."
"Elastic Security actually has a very good cost-benefit ratio compared to other vendors in the market."
"This is one of the best open-source log management and log analyzer tools in the world."
"We chose Elastic Security because we felt it was the most flexible, cost-effective solution to provide the results needed."
"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."
"Security Onion is the most mature solution in the market."
 

Cons

"Continuous upgrades can be quite inconvenient. My security testing team continuously reports vulnerabilities, and we have to fix and update the versions frequently."
"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."
"We'd like to see some more artificial intelligence capabilities."
"The solution could offer better reporting features."
"The interface could be more user friendly because it is sometimes hard to deal with."
"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."
"If you compare this with CrowdStrike or Carbon Black, they can improve."
"I do not have any specific recommendations for improvements in Elastic Security, but I feel that the AI module should get more mature."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
 

Pricing and Cost Advice

"Affordable but with additional costs"
"Compared to other tools, Elastic Security is a cheaper solution."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"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 solution is not expensive and costs around ten dollars a month."
"When compared to other products, the price is average or on the low side."
"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."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
